Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The existing SIM card 400 swiping and flipping is mainly realized by active commands of the SIM card 400. In the NFC non-access channel interaction process of the POS terminal 200 and the SIM card 400, since the SIM card 400 cannot obtain an available proactive command Handler active command handle in the non-access channel mode, and can only obtain an available active command handle in a non-real-time STK STATUS event, the active command is called to implement a card swiping and screen flipping, which may cause a problem of delayed screen flipping, and directly affect the card swiping experience of the user.
As shown in fig. 1, fig. 1 is a flowchart illustrating steps of a conventional SIM card swiping and screen flipping method, including steps S110 to S130:
step S110, the POS terminal 200 sends an APDU command to the SIM card 400 through the SWP protocol;
step S120, the SIM card 400 receives the APDU command from the POS terminal 200, calls an active command and sends the active command to the intelligent terminal 500 system;
step S130, the intelligent terminal 500 system performs a pop-up prompt after receiving the active command.
Specifically, in the conventional SIM card swiping and screen flipping method, the POS terminal 200 makes NFC non-contact touch with the smart terminal 500, such as a mobile phone, and interacts with the SIM card 400 through an APDU instruction. The interactive instruction is directly sent to the SIM card 400 for processing through the SWP protocol without passing through any third party APP. When processing the APDU command, the SIM card 400 invokes an active command to notify the mobile phone system to perform a pop prompt, where the active command illustratively includes DisplayText, launchBrowser, and the like.
In order to overcome the non-real-time defect of card swiping and screen flipping through an active command of the SIM card 400, the SIM card swiping and screen flipping method, the SIM card swiping and screen flipping system and the storage medium are provided, so that the intelligent terminal can timely and stably display necessary screen flipping display interaction confirmation information or interaction result information during card swiping interaction, and the card swiping experience of a user is improved.
For ease of understanding, the following provides an explanation of terminology:
APDU application protocol data unit (application protocol data Unit). Protocol data unit PDU (protocol data unit) refers to a unit of data transferred between peer layers. The PDU of the physical layer of the protocol data unit (protocol data unit) is a data bit (bit), the PDU of the data link layer is a data frame (frame), the PDU of the network layer is a data packet (packet), the PDU of the transport layer is a data segment (segment), and the PDU of other higher layers is data (data). APDUs are commonly used for data interactive use of IC cards and business development of IC cards.
Referring to fig. 2, fig. 2 is a first flowchart of a SIM card swiping and screen flipping method provided by the embodiment of the invention, applied to a POS terminal 200, and including steps S210 to S220:
step S210, sending the information unit instruction to the target service module 300.
Specifically, the information unit instruction may be an APDU instruction, and when the smart terminal performs NFC non-contact interaction with the POS, the POS terminal 200 sends the APDU instruction to the target service module 300.
Step S220, receiving the information unit response instruction from the target service module 300, and performing service processing based on the target information in the information unit response instruction, wherein the service processing includes credit withdrawal.
Specifically, the information unit responds to the APDU command, and the POS terminal 200 performs a service process based on target information in the APDU command. Illustratively, the POS terminal 200 requests payment, and the POS terminal 200 performs the transaction amount teller through the instruction including the transaction-related information returned by the target service module 300.
Referring to fig. 3, fig. 3 is a second flowchart of a SIM card swiping and screen flipping method provided by the embodiment of the invention, which is applied to a target service module 300, and includes steps S310 to S330:
step S310 receives the information unit command sent by the POS terminal 200, and sends the information unit command to the SIM card 400.
Step S320, receiving the information unit response instruction from the SIM card 400, and sending the information unit response instruction to the POS terminal 200.
Specifically, the received information unit instruction sent by the POS terminal 200 is sent to the SIM card 400 through a machine-card channel interface, such as OpenMobile API, telephony Manager, OMAPI, or bluetooth channel technology, to forward the instruction to the SIM card 400 for processing, and return the response data of the SIM card 400 to the POS terminal 200.
And step S330, acquiring the transaction information in the information unit response instruction, determining the transaction state according to the keyword in the transaction information, and calling a transaction interface corresponding to the transaction state to perform screen flipping.
Specifically, the target service module 300 is responsible for monitoring an interaction instruction and response data between the POS terminal 200 and the SIM card 400, determining transaction information such as a response status word, a terminal identifier, transaction time, transaction amount, wallet balance, and the like in the interaction instruction through a service logic preset by the target determination service module 300, and determining a transaction status according to a keyword in the transaction information. And calling a related API provided by the intelligent terminal system in real time according to the monitoring result to perform screen popup notification of the service information for the user. It is noted that the target service module 300 is also responsible for handling other extended matters including, but not limited to, logging, transaction history, asynchronous network notification, different versions of SIM card 400 application compatibility handling, and the like. In order to ensure the card swiping experience of the user, other extension modules should be executed as fast as possible, and asynchronous concurrent execution should be adopted for time-consuming operations. Furthermore, the target service module 300 may adopt host-based card emulation, which is a smart card emulation technology based on software and without providing a Secure Element SE (Secure Element), and most of the current mainstream Android mobile phone systems support the HCE technology. The HCE technology on the Android system is realized through system services, the service using method has the great advantage that the service using method can be operated in the background all the time without a user interface, and developers can realize the HCE service only by rewriting the service base class related method provided by the system and carrying out corresponding installation configuration.
Referring to fig. 4, fig. 4 is a third flowchart of a SIM card swiping and screen flipping method provided by the embodiment of the invention, which is applied to a SIM card 400, and includes steps S410 to S420:
step S410, responding to the information unit instruction sent by the target service module 300 to obtain transaction information;
step S420, based on the transaction information, sending an information unit response instruction to the target service module 300, where the information unit response instruction includes the transaction information.
Referring to fig. 5, fig. 5 is a fourth flowchart illustrating that the SIM card swiping and screen flicking system provided in the embodiment of the present invention in fig. 5 executes a method for swiping a SIM card and screen flicking, where the method is applied to the SIM card swiping and screen flicking system 100, and includes steps S510-S520:
step S510, the POS terminal 200 sends an information unit instruction to the target service module 300;
step S520, the target service module 300 receives the information unit instruction sent by the POS terminal 200, and sends the information unit instruction to the SIM card 400;
step S530, the SIM card 400 responds to the information unit command sent from the target service module 300 to obtain the transaction information;
step S540, the SIM card 400 sends an information unit response instruction to the target service module 300 based on the transaction information, wherein the information unit response instruction includes the transaction information;
step S550, the target service module 300 receives the information unit response instruction from the SIM card 400, and sends the information unit response instruction to the POS terminal 200;
step S560, the target service module 300 acquires the transaction information in the information unit response instruction, determines the transaction state according to the keyword in the transaction information, and calls a transaction interface corresponding to the transaction state to perform screen flipping;
in step S570, the POS terminal 200 receives the information unit response instruction from the target service module 300, and performs a service process based on the target information in the information unit response instruction, where the service process includes credit withdrawal.
Specific examples are provided below:
in the conventional pop-up method, the POS terminal 200 directly sends the APDU command to the SIM card 400 for processing, the SIM card 400 completes the command processing and responds to data, and there may be multiple APDU command interactions during the command processing, and the SIM card 400 cannot directly invoke the active command to pop up the screen during the command processing, so the SIM card 400 needs to save the relevant state during the command processing, wait for the system STATUS event to obtain the available active command handle, and then invoke the relevant active command. The mobile phone system cannot ensure real-time triggering of the STATUS event, so that screen popup confirmation or prompt cannot be presented in time, and the problem of screen popup delay occurs.
After improvement, in the interaction process between the POS terminal 200 and the SIM card 400, the system of the smart terminal does not send the APDU instruction directly to the SIM card 400 for processing, but the client APP implements HCE service and receives the APDU instruction, and the HCE service instruction forwarding module forwards the instruction to the SIM card 400 for processing through the set-card channel interface. Through the processing, the HCE service instruction monitoring module can monitor and analyze the interaction information and the interaction result of the instruction in real time, and the related API of the mobile phone system is called to feed back the user in real time, so that the card swiping experience of the user is improved. The target service module 300 is established to forward and monitor the status of the information unit command. The intelligent terminal realizes the target service module 300 and the POS terminal 200 does not need to be changed, in the specific embodiment, the target service module 300 does not realize the non-connected application logic of the SIM card 400, and only forwards the information unit instruction to the non-connected application of the SIM card 400; the target service module 300 forwards the information unit instruction to the SIM card 400 through a machine-card channel, wherein the machine-card channel technology includes, but is not limited to, openMobile API, telephony Manager, OMAPI, or bluetooth channel technology; the target service module 300 monitors the instruction interaction information of the information unit and calls the intelligent terminal system service to realize screen flipping; the monitored instruction interaction information includes, but is not limited to, a response status word, and APDU transaction message key fields, such as: transaction time, transaction amount, wallet balance, etc. Further, another embodiment is provided below: the smart terminal 500 may simulate logic functions and pop-screen functions of all non-connected applications of the SIM card 400 using the target service module 300. But this is done at the expense of abandoning the multi-application capabilities of SIM card 400 and the established good machine-card non-compatibility.
Referring to fig. 5, fig. 5 is a fourth flowchart illustrating that the SIM card swiping and screen popping system provided in the embodiment of the invention in fig. 5 executes a SIM card swiping and screen popping method, and the SIM card swiping and screen popping system 100 is applied, and includes:
the POS terminal 200 for transmitting the information unit command to the target service module 300; receiving an information unit response instruction from the target service module 300, and performing service processing based on target information in the information unit response instruction, wherein the service processing comprises credit withdrawal;
the target service module 300 is configured to receive an information unit instruction sent by the POS terminal 200, and send the information unit instruction to the SIM card 400; receiving an information unit response instruction from the SIM card 400 and transmitting the information unit response instruction to the POS terminal 200; the information acquisition unit responds to the transaction information in the instruction, determines a transaction state according to a keyword in the transaction information, and calls a transaction interface corresponding to the transaction state to perform screen flipping;
the SIM card 400 is configured to respond to the information unit instruction sent by the target service module 300 to obtain transaction information; based on the transaction information, an information unit response instruction is sent to the target service module 300, wherein the information unit response instruction includes the transaction information.
It is noted that the target service module 300 and the SIM card 400 are both located in the smart terminal 500, and the smart terminal 500 may be a mobile phone, for example. After the bank card and the NFC technology are combined together, the card swiping interaction between the POS terminal 200 and the smart terminal 500 is realized, and in an actual application scenario, the target service module 300 and the SIM card 400 located in the smart terminal 500 will interact with the POS terminal only by performing a non-contact transaction between the smart terminal 500 and the POS terminal 200.
