Detailed Description

To make the objects, technical solutions and advantages of one or more embodiments of the present disclosure more apparent, the technical solutions of one or more embodiments of the present disclosure will be described in detail and completely with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present specification, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of one or more embodiments of the present specification.

The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.

In the prior art, a scheme for realizing an unmanned operation mode of shops by using a technical means to carry out intelligent automatic processing has appeared. Such as an unmanned vending machine, an unmanned convenience store, etc. However, when the above-mentioned unattended operation mode of the shop is implemented, a large amount of special equipment is often required to be deployed at the shop, and the implementation cost is high, so that the method is not suitable for the situation that a shop manager needs to leave the shop temporarily and conduct unattended operation of the shop in a short period. And at present, when a customer purchases at an unmanned shop, remote communication with a shop manager often cannot be carried out, so that the shopping experience of the customer is influenced.

In order to solve the defects in the prior art, the scheme provides the following embodiments:

fig. 1 is a flowchart illustrating an instant messaging method according to an embodiment of the present disclosure. From a procedural perspective, the executing subject of the process may be a payment device deployed at the target store, or an application hosted at the payment device. As shown in fig. 1, the process may include the following steps:

step 102: acquiring a trigger operation of a first user on an instant messaging control at the payment device.

In embodiments of the present description, the destination store is typically provided with a payment device for collecting payment to the customer using the payment device. That is, the payment device may be a device that is usually set at a target store, and is not a device that is intentionally added to implement the instant messaging method in the embodiment of the present specification.

Wherein the target store is typically a store having a physical place of business. The target store can sell real objects, for example, the target store can be a shop or supermarket selling real objects such as daily necessities and food; alternatively, the target store may also sell services, for example, the target store may be a car wash that sells self-service car washes, a nail shop that sells self-service nail care, and the like. Typically, customers have the ability to do shopping, consumption, payment, etc. on their own at the target store.

In the embodiments of the present description, the payment device may have a plurality of operation modes. For example, when a shop manager leaves a target shop and needs to achieve unmanned operation of the target shop, the out-of-store operation mode of the payment device may be selected, and at this time, an instant messaging control may be displayed at a display interface of the payment device, so that when a first user performs self-service shopping at the target shop, the instant messaging control may be triggered to communicate with the shop manager (e.g., a second user). The implementation manner of the triggering operation of the instant messaging control by the first user may be various, for example, a click operation, a long-time press operation, a mouse hovering operation, and the like for the instant messaging control are not specifically limited.

In practical application, when the payment equipment is in an off-store operation mode, the instant messaging control can be directly displayed in a display interface; or, after the first user is identified to carry out the target shop, the instant messaging control can be displayed; alternatively, the instant messaging control may be presented after the first user triggers the payment device, which is not limited in particular.

In practical application, when a shop manager is located in a target shop and operates the target shop manually, a common operation mode of the payment device can be selected, and at the moment, the display interface of the payment device can not display the instant messaging control, so that troubles caused by the fact that the first user triggers the instant messaging control by mistake are avoided.

Step 104: in response to the triggering operation, a registered account of a second user bound with the payment device is determined.

In this embodiment, the registered account of the second user is usually pre-bound at the payment device, so that the registered account is used as an account for answering instant messaging. Specifically, a single registered account may be bound at the payment device; alternatively, multiple registered accounts may be bound to the payment device, and the multiple registered accounts may be accounts of the same second user or accounts of different second users, which is not limited in particular.

If a plurality of registered accounts bound with the payment device exist, the shop manager can preset the use priority of each registered account, and sequentially try to establish instant messaging connection with each registered account from high to low according to the use priority until the instant messaging connection with any registered account is established successfully, so that the establishment success probability of the instant messaging connection is favorably improved. Or, each registered account bound with the payment device and the corresponding identification information of the second user may be displayed to the first user, so that the first user may select any registered account to establish the instant messaging connection according to actual requirements.

In practical applications, since the payment device generally needs to establish a binding relationship with a collection account of a shop manager (e.g., a payment account of a second user), after the customer is collected with the payment device, funds at the account of the customer can be transferred to the collection account. Based on the method, the collection account bound with the payment device can also be used as the registered account of the second user bound with the payment device, and the method is beneficial to simplifying the setting operation of the shop manager on the payment device.

In this embodiment of the present specification, the payment device may locally store account identification information of the registered account of the second user bound thereto, so that in step 104, the account information of the registered account of the second user bound to the payment device may be extracted from the information locally stored in the payment device. Alternatively, the account information of the registered account of the second user bound to the payment device may be stored in the server, so that the payment device may also obtain the account information of the registered account of the second user bound to the server from the server when step 104 is executed. This is not particularly limited.

Step 106: establishing instant communication connection between the payment device and a target device logged with the registered account; and the instant messaging connection is used for enabling the first user to carry out instant messaging with the second user.

In this embodiment of the present specification, an application to which a registered account of the second user bound to the payment device belongs may be referred to as a target application. The target application program is required to be carried at the target device of the second user, and the registered account is logged in at the target application program, so that instant communication connection is established with the payment device based on the target application program at the target device, the second user can remotely guide the first user to carry out self-service shopping and settlement, and unmanned operation of a target shop is achieved. In practical applications, the type of the target application program may be various, for example, an instant messaging application, a payment application, or other types of applications, and the like, which is not particularly limited.

In the method in fig. 1, after a first user triggers an instant messaging control at a payment device deployed at a target store, the payment device may determine a registered account of a second user bound to the first user, and establish an instant messaging connection between the payment device and the target device logged in with the registered account, so that the first user and the second user can perform instant messaging based on the instant messaging connection. According to the scheme, the convenience of communication between the customer (namely, the first user) and the shop manager can be improved under the condition that the shop manager (namely, the second user) leaves the target shop, and due to the fact that instant communication is conducted by existing payment equipment at the target shop, other equipment does not need to be newly added, self-service shopping and payment can be achieved by the first user under the guidance of the second user, unmanned operation of the shop is achieved, and the improvement cost of the shop in unmanned operation is reduced.

Based on the process in fig. 1, some specific embodiments of the process are also provided in the examples of this specification, which are described below.

In this embodiment of the specification, in order to facilitate the second user to remotely monitor the operation condition of the target store, the payment device may further send a prompt message to the second user after recognizing that the first user enters the target store.

Specifically, the scheme in fig. 1 may further include:

if the first user is detected to enter the target store, user prompt information is generated; the user prompt information is used for prompting the second user that the first user enters the target store.

And sending the user prompt information to the target equipment logged with the registered account.

In this embodiment of the specification, the payment device is usually a networked device, and therefore, the user prompt message may be sent to the target device logged in with the registered account of the second user bound to the target device through the internet, so that the second user may timely know that the first user enters the target store.

Specifically, the payment device may send the user prompt information to a server device of a target application (i.e., an application to which a registered account of a second user bound to the payment device belongs), so that the server device is used to forward the user prompt information to the target device logged in with the registered account of the second user.

In practical application, the payment device may locally store the account information of the registered account of the second user, so that the payment device may further send the account information of the registered account of the second user to the server device, so that the server device can know the receiving account of the user prompt information.

In practical applications, a video monitoring device is usually disposed at a target store to collect a monitoring video of the target store in real time. Based on this, after looking up the user prompt information, the second user may also need to view the monitoring video at the target store, and at this time, the second user may view the monitoring video from the monitoring application corresponding to the video monitoring device.

Or, the second user can directly view the monitoring video from the target application program based on the payment device at the target store, so as to avoid inconvenience caused by the fact that the second user needs to execute application jump operation when viewing the monitoring video and the user prompt information.

Specifically, the payment device at the target store may be in wired connection or wireless connection with the video monitoring device, so that the payment device may obtain the monitoring video collected by the video monitoring device, and may actively send the monitoring video to the target device logged in with the registered account of the second user bound to the monitoring video. Or after receiving a monitoring video sending instruction generated by the second user by using the registered account, sending the monitoring video to the target device logged in with the registered account, so that the second user can view the monitoring video of the target shop from the target device.

In the embodiment of the specification, prompt information can be broadcasted to the first user by using the payment device, so that the first user can know that the target shop is in an unmanned operation state at present, and can know that instant messaging can be performed between the payment device and the second user, and self-service shopping and settlement can be performed.

Based on this, the method in fig. 1 may further include:

if the first user is detected to enter the target store, voice prompt information is broadcasted; the voice prompt message may be used to prompt the first user to utilize the payment device to conduct instant messaging with the second user.

In an embodiment of the present specification, the voice prompt message may further prompt that a shop manager of the target shop is not located in the target shop currently, and the target shop is in an unattended operation mode, so that the first user can know a business mode of the target shop conveniently.

In the embodiment of the specification, the first user is prompted in a voice broadcasting mode, so that the prompt information touch rate is better, and the first user does not need to assist in executing other operations, thereby being beneficial to improving the experience of the first user. In practical applications, the text content corresponding to the voice prompt message may be displayed in the form of text, graphics, and the like on the display screen of the payment device, which is not limited specifically.

In this embodiment of the present description, since the payment device generally needs to perform the operation of sending and broadcasting the related prompt information after detecting that the first user enters the target store, a detection scheme for an event that the first user enters the target store is further provided in this embodiment of the present description.

Specifically, the method in fig. 1, detecting that the first user enters the target store, may specifically include:

receiving user entrance information sent by user detection equipment at the target shop; the user access information is used for reflecting that the first user accesses the target store.

In this embodiment, a target store is generally provided with a user detection device having a user entry behavior detection function, for example, a video monitoring device, a guest greeting device, and the like. Thus, wired connection or wireless connection between the user detection device and the payment device can be established, so that the user detection device can send user entrance information to the payment device after detecting that the first user enters the target shop. Based on this, if the payment device receives the user progress information, it may indicate that the first user is detected to enter the target store.

For ease of understanding, the principle of the user detection device detecting the first user entering the target store is explained herein.

At present, video monitoring equipment generally has human body detection and tracking capabilities, and therefore, the video monitoring equipment with a monitoring area as an internal area or an inlet area of a target shop can be used for detecting the behavior of a first user entering the target shop based on the human body detection and tracking capabilities of the video monitoring equipment.

The greeting device may generally refer to a device that broadcasts greeting information (e.g., welcome information, etc.) upon recognizing that a user enters a target store. At present, the guest-greeting device is usually provided with a sensing device such as a thermal infrared sensor or a light resistor, and when a user passes through the guest-greeting device, the sensing device at the guest-greeting device is triggered, so that a behavior that the first user enters a target store is detected.

In practical application, if the payment device is equipped with the image collector, the payment device may also be used to collect an image of the target store by itself, and analyze the collected image to detect a behavior of the first user entering the target store. However, since the image collector mounted on the payment device is generally suitable for collecting images within a small range, there may be a case where a user entering a target store is missed.

In the embodiment of the present specification, an implementation manner of establishing an instant messaging connection between a payment device and a target device logged in with a registered account of a second user is also provided. Specifically, the method comprises the following steps:

the payment device may send a call creation request to the first server.

Receiving call unique identification information fed back by the first server in response to the call creation request.

Sending the unique call identification information to the target equipment logged in with the registered account; the target device is used for establishing instant communication connection with the payment device by using the call unique identification information.

In the embodiment of the present specification, the first server is generally a server providing an instant messaging service. The first server can create a virtual call room, and send the information to be transmitted at each device/account joined in the same call room to other devices/accounts in the call room, thereby realizing instant messaging between different devices/accounts.

Specifically, after receiving a call creation request sent by the payment device, the first server may create a virtual call room, and feed back unique room identification information of the call room as call unique identification information to the payment device, where the payment device has added the call room corresponding to the call unique identification information. The payment device further needs to send the call unique identification information to the target device logged in with the registered account of the second user, so that the target device joins the call room where the payment device is located at the first server by using the call unique identification information, and thus an instant communication connection between the two is established. Subsequently, instant communication between the payment device and the target device can be realized based on the first server.

In practical applications, the service provider of the first server may provide a Software Development Kit (SDK) for implementing an instant messaging function to the user, and the payment device and the target device generally need to be loaded with the SDK to establish an instant messaging connection therebetween based on the first server.

In an embodiment of this specification, the sending the unique call identification information to the target device logged in with the registered account may specifically include:

sending instant messaging connection information carrying the unique call identification information and the account information of the registered account to a second server; and the second server is used for sending an instant messaging connection request carrying the unique call identification information to the target equipment logged in with the registered account according to the instant messaging connection information.

In this embodiment, the second server is generally a server device of a target application (i.e., an application to which a registered account of the second user bound to the payment device belongs), for example, if the registered account of the second user is a payment account registered by the second user at the payment application, the second server may be the server device of the payment application. Therefore, the instant communication connection request carrying the unique call identification information can be sent to the target equipment logged in with the registered account by using the second server. In practical applications, the first server and the second server may be the same server or different servers, and the service providers to which the first server and the second server belong may be the same or different, which is not limited specifically.

In the embodiments of the present specification, the type of the instant communication connection established between the payment device and the target device may be various. For example, when the payment device is a face-brushing payment device, the instant communication connection may include, because the payment device typically has video capture capabilities: the video call connection is connected with the voice call.

Correspondingly, step 106: establishing an instant messaging connection between the payment device and a target device logged in with the registered account may specifically include:

establishing a video call connection between the payment device and a target device logged in with the registered account; or,

and establishing voice call connection between the payment device and the target device logged in with the registered account.

In this embodiment of the present description, if there are multiple types of instant messaging connections that can be established between the payment device and the target device, the payment device may display multiple instant messaging controls that correspond to the multiple types of instant messaging connections one to one, so that the first user may trigger the specified instant messaging control according to actual needs, and thus establish an instant messaging connection of a type corresponding to the specified instant messaging control with the target device, which is beneficial to improving the experience of the first user.

In practical application, if the payment device does not have the video acquisition capability but has the voice acquisition capability, the payment device can only establish voice call connection with the target device, and at the moment, a single instant messaging control is displayed at the payment device, so that trouble brought to the first user is avoided.

Or, if the payment device does not have the video acquisition capability but has the voice acquisition capability, a video call connection between the payment device and the target device may also be established, and only at this time, the payment device may send the video data of the first user, which is acquired by the video monitoring device at the target store, to the target device, or the payment device may not send the video data related to the first user to the target device, so that the second user may not obtain the image data of the first user, but the first user may receive the video data of the second user from the payment device, which is beneficial to improving the experience of the first user.

In the embodiment of the specification, when the second user performs instant messaging with the first user, the second user can guide the first user to perform self-service shopping and settlement, so that unmanned operation of a target shop is realized. Thus, the first user may also need to perform a payment operation with the payment device to pay for the specified goods that the first user needs to purchase from the target store.

Based on this, step 106: after the instant communication connection between the payment device and the target device logged in with the registered account is established, the method may further include:

acquiring a payment operation executed by the first user aiming at the payment device; the payment operation is used for paying for the specified goods at the target store.

And generating payment order information of the first user in response to the payment operation.

In this embodiment of the present specification, the specific goods at the target store may be a physical article, or may be a non-physical service (for example, a self-service car washing service, etc.) that the first user may enjoy at the target store, and this is not particularly limited.

In this embodiment, if the first user needs to pay for a specific commodity at the target store, the payment device generally needs to determine an amount (i.e., an amount to be paid) that needs to be paid for the specific commodity purchased by the first user. In practical applications, the payment device may obtain the amount to be paid in various ways.

Specifically, before the obtaining of the payment operation performed by the first user with respect to the payment device, the method may further include:

acquiring the amount to be paid sent by a cash register in communication connection with the payment device; the amount to be paid is generated according to an operation performed by the first user on the cash register device; or,

acquiring an amount to be paid input by the first user at the payment device; or,

acquiring the amount to be paid sent by the second user based on the target device logged with the registered account;

the obtaining of the payment operation executed by the first user for the payment device specifically includes:

and acquiring the operation of the first user for paying the amount to be paid, which is executed by the payment device.

In the embodiment of the present specification, if a cash register device connected to a payment device is disposed at a target store, the cash register device may be used to determine the amount of money to be paid for a specific commodity in a manner of scanning a barcode of the specific commodity. The cash register device can also send the determined amount to be paid to the payment device, so that the first user can pay the amount to be paid by using the payment device conveniently.

Or, the payment device itself may have a capability of enabling the first user to manually input the amount to be paid, for example, the payment device may be provided with a keyboard, so that the first user may manually input the amount to be paid by operating the keyboard, and thus the payment device may obtain the amount to be paid, thereby facilitating the first user to pay the amount to be paid by using the payment device.

Or the second user can input the amount to be paid by using the registered account bound with the payment device, and the amount to be paid is forwarded to the payment device through the server device of the application to which the registered account belongs, so that the payment device can acquire the amount to be paid, which is beneficial to simplifying the operation of the first user and guaranteeing the authenticity and the accuracy of the amount to be paid.

In practical application, if the payment device is a face-brushing payment device, the operation performed by the first user for the payment device to pay the amount to be paid may be a face-brushing payment operation, or an operation of presenting a payment code to the payment device to pay, which is not particularly limited.

In the embodiment of the specification, functions of instant messaging, voice prompt broadcasting, user prompt information sending, payment amount acquisition from the target device and the like realized on the basis of the payment device can be realized by updating a software installation package of the payment device deployed at the target store without purchasing and newly adding other payment devices again, so that the transformation cost of the target store when the target store is operated without people can be reduced.

Based on the same idea as the scheme shown in fig. 1, the embodiment of the present specification further provides another instant messaging method. Fig. 2 is a flowchart of another instant messaging method provided in an embodiment of the present disclosure. The execution subject of the process may be a target device logged in a registered account of a second user bound to a payment device, wherein the payment device is deployed at a target store; alternatively, the execution subject of the flow may be an application program registered with the registered account. As shown in fig. 2, the process may include:

step 202: receiving an instant messaging connection request of the payment device; the instant messaging connection request is generated in response to a triggering operation of a first user for an instant messaging control at the payment device.

In this embodiment of the present specification, after performing the triggering operation mentioned in step 102 in fig. 1 for the instant messaging control at the payment device, the first user may cause the execution subject in the scheme in fig. 2 to receive an instant messaging connection request in response to the triggering operation.

Step 204: and acquiring a connection instruction aiming at the instant communication connection request.

In this embodiment of the specification, the target device is usually loaded with an application (i.e., a target application) to which a registered account of the second user bound to the payment device belongs, so that after the instant messaging connection request is obtained, the instant messaging connection request can be displayed at the target application. If the second user agrees to establish the instant messaging connection with the payment device, the target application program can be operated to enable the target device to obtain a connection instruction for the instant messaging connection request.

If the second user does not agree to establish the instant messaging connection with the payment device, the target application program can be operated to enable the target device to obtain a connection prohibition instruction aiming at the instant messaging connection request, so that the response of the instant messaging connection request is terminated; or, no operation may be executed on the target application program, so that the target device terminates the response of the instant messaging connection request when determining that the duration of acquiring the instant messaging connection request reaches a specified duration and a connection instruction for the instant messaging connection request is not acquired; the target device and the payment device are prevented from establishing instant communication connection, and therefore the communication willingness of the second user is guaranteed.

Step 206: establishing an instant communication connection between the target device and the payment device in response to the connection instruction; and the instant messaging connection is used for enabling the first user to carry out instant messaging with the second user.

In this embodiment of the present description, the step 206 establishes the instant messaging connection between the target device and the payment device, and the technical principles adopted by the step 206 to establish the instant messaging connection between the target device and the payment device mentioned in the step 106 in fig. 1 may be the same, and are not described herein again.

After the instant communication connection between the target device and the payment device is established, the second user and the first user can carry out instant communication based on the instant communication connection, so that the second user can remotely guide the first user to carry out self-service shopping and settlement, and unmanned operation of a target shop is realized.

In the method in fig. 2, after triggering an instant messaging control at a payment device deployed at a target store, a target device, which has logged in a registered account of a second user bound to the payment device, of a first user may receive an instant messaging connection request, and if the target device obtains a connection instruction for the instant messaging connection request, an instant messaging connection between the payment device and the target device may be established, so that the first user and the second user may perform instant messaging based on the instant messaging connection. According to the scheme, the convenience of communication between the customer (namely the first user) and the shop manager can be improved under the condition that the shop manager (namely the second user) leaves the target shop, and due to the fact that instant communication is conducted by existing payment equipment at the target shop, unmanned operation of the shop can be achieved without newly adding other equipment, and the improvement cost of the shop in the unmanned operation mode is reduced.

Based on the method in fig. 2, some specific embodiments of the method are also provided in the examples of this specification, which are described below.

In the embodiment of the present specification, step 202: receiving an instant messaging connection request of a payment device may specifically include:

receiving the instant messaging connection request sent by a second server; the instant messaging connection request carries call unique identification information, and the call unique identification information is generated by the first server in response to the call establishment request of the payment device.

Correspondingly, step 206: establishing an instant messaging connection between the target device and the payment device may specifically include:

and the target device establishes instant communication connection with the payment device by using the unique call identification information.

In this embodiment of the present specification, the payment device may include a face-brushing payment device; the registered account may be a payment account of the second user at a payment application; the second server may be a server device of the payment application. And the first server may be a server providing an instant messaging service. In practical applications, the first server and the second server may be the same or different, and both may belong to the same service provider or different service providers, which is not limited specifically.

In practical applications, the payment device may request the first server to create a virtual call room, and cause the first server to feed back unique room identification information corresponding to the call room as call unique identification information, so as to send the call unique identification information to the target device. The payment application at the target device logged into the registered account of the second user may then send the call unique identification information to the first server to join the call room in which the payment device is located. Subsequently, the first server can transmit the information to be transmitted of the payment device and the target device which join the same call room, so that the second user can perform instant communication with the first user at the payment device based on the payment application.

In this embodiment of the present description, when the payment device is a face-brushing payment device, there are various types of instant messaging connections that can be established between the target device and the payment device. Based on this, the target device establishes an instant messaging connection with the payment device by using the unique call identification information, which may specifically include:

the target device establishes video call connection with the payment device by using the call unique identification information; or,

and the target device establishes voice call connection with the payment device by using the call unique identification information.

In this embodiment of the present specification, the second user may further set, by using the target device, an amount to be paid at the payment device according to a communication situation with the first user, so that the first user pays the amount to be paid at the payment device.

Based on this, step 206: after the instant communication connection between the target device and the payment device is established, the method may further include:

acquiring the amount to be paid, which is input by the second user and corresponds to the first user; the amount to be paid is an amount due for a specified commodity purchased by the first user from the target store.

And sending the amount to be paid to the payment equipment.

In this embodiment of the description, the second user may input the amount to be paid at a target application program (that is, an application program to which a registered account of the second user bound to the payment device belongs) carried at the target device, and send the amount to be paid to the payment device through the server device of the target application program, so that the first user pays the amount to be paid at the payment device, and the operation convenience in self-service shopping and payment of the first user is improved.

In this embodiment, after the first user enters the target store, the second user may have a need to know the event. Based on this, the method in fig. 2 may further include:

acquiring user prompt information; the user prompt information is generated by the payment device after the first user is detected to enter the target store, and the user prompt information is used for prompting the second user that the first user enters the target store.

And displaying the user prompt information.

In this embodiment, the target application (i.e., the application to which the registered account of the second user bound to the payment device belongs) may be utilized to obtain and display the user prompt information. Subsequently, the second user can also view the monitoring video at the target shop based on the target application program, so that the second user can remotely monitor the running condition of the target shop.

In the embodiment of the description, functions such as instant messaging, user prompt information display, and to-be-paid amount setting, which are realized based on a target application program, can be realized by updating a software installation package of the target application program, and a second user does not need to buy a new mobile terminal device again or add a new mobile terminal device, so that the transformation cost of the target store when the target store is operated without people is reduced.

As shown in fig. 3, the instant communication process may involve the first user, the payment device, the target device, the second user, etc. executing the principal. Wherein the registered account of the second user bound with the payment device is logged on at the target device.

In the instant messaging stage, a first user can enter a target shop, and payment equipment deployed at the target shop can receive user entering information sent by user detection equipment at the target shop; and broadcasting voice prompt information, wherein the voice prompt information is used for prompting the first user to utilize the payment device to carry out instant messaging with the second user and the second user leaves a target shop. The payment device may further generate user prompt information for prompting the second user that the first user enters the target store, and send the user prompt information to the target device logged in with the registered account of the second user bound to the payment device. Correspondingly, the target device may obtain and display the user prompt information so that the second user can refer to the user prompt information.

The first user may also trigger for an instant messaging control at the payment device so that the payment device may obtain a trigger operation for the instant messaging control at the payment device. In response to the triggering operation, the payment device may determine a registered account of the second user bound to the payment device, and send a call creation request to the first server; receiving unique call identification information fed back by a first server; and sending an instant messaging connection request carrying the unique call identification information to the target equipment logged in with the registered account based on the second server.

The target device may receive and display the instant communication connection request of the payment device, and the second user may perform a connection operation for the instant communication connection request, so that the target device obtains a connection instruction for the instant communication connection request. The target device can also establish instant messaging connection with the payment device based on the unique call identification information carried in the instant messaging connection request, so that the first user and the second user can carry out instant messaging.

In the payment phase, the first user may perform a payment operation for a payment device to pay for a specified good at the target store based on the instant messaging content with the second user. And the payment equipment responds to the payment operation, and then generates payment order information of the first user, so that the first user can finish self-service shopping and payment at the target shop, and an unmanned operation mode of the target shop is realized.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, as for the apparatuses shown in fig. 6 and 7, since they are substantially similar to the method embodiments, the description is simple, and the relevant points can be referred to the partial description of the method embodiments.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital character system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium that stores computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and embedded microcontrollers, examples of which include, but are not limited to, the following microcontrollers: the ARC625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be conceived to be both a software module implementing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
