The every other embodiment obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1 and Fig. 2, the embodiments of the present invention, it is a kind of can fingerprint recognition and dynamic two-dimension code electronic card
Piece 1, including shell 10, main control unit 20, RFID antenna 30, Bluetooth antenna 40, attendance module.
Main control unit 20 connects power supply unit, is set in shell 10, RFID antenna 30, Bluetooth antenna 40 and main control unit
20 are connected, and the display unit 50 for showing dynamic two-dimension code, display unit 50 and 20 phase of main control unit are arranged on shell 10
Connection.
Main control unit 20 connects two-dimensional code generation module by SPI interface.
In practice, can also highly integrated two-dimensional code generation module in main control unit 20.
Electronic card 1 is integrated with attendance module, is short distance attendance module respectively：NFC module and/or remote work attendance mould
Block：2.4G module.
Display unit 50 is set to the first half of shell 10, is arranged in the lower half of shell 10 and is connected with main control unit 20
For starting the activation member that dynamic two-dimension code is shown, such as：Fingerprint identification module 60.
Display unit 50 includes LCD display, and LCD display two-dimensional code display usually shows that screen will not be lit, directly
Start to user and just can be lit simultaneously two-dimensional code display pattern when fingerprint identification module 60 carries out fingerprint recognition.
The product type of two-dimensional code generation module can be：STM3280C51；
20 main element of main control unit is master chip, and the product type used can be for：nrf52832；
The product type of fingerprint identification module 60 can be：AS608 optical fingerprint identification modules；
The optical fingerprint identification module has 360 degree rotation identification function, provides USB, UART (RS232) and SPI etc. and connects
Mouth mode.
The above chip or module are common chip or module and have auxiliary circuit, therefore operation principle and process are not
It repeats again.
In practice, attendance module and main control unit 20 can be integrated on one piece of circuit board, can also be collected by height
At two-dimensional code generation module in main control unit 20, Quick Response Code generating algorithm can also concentrate on running on master chip.Quick Response Code
Generating algorithm also can all concentrate on master chip running, at this point, the chip of ARM Cotext-M4 can be used in master chip, dominant frequency is
64MHz。
The generally rectangular configuration of shell 10.
Wherein, the RFID antenna 30 in Fig. 2, Bluetooth antenna 40, attendance module, power supply module and fingerprint identification module 60
Main control unit 20 is connected in the form of SPI interface.
User fingerprints can be directed into private client such as the acquisition of fingerprint logging apparatus in the memory of main control unit 20, two dimension
Code generation module and the ID of user are bindings.
The operation principle of this product is：Fingerprint identification module 60 is pressed, main control unit 20 has recognized the identity of user, to
Two-dimensional code generation module sends out the instruction of in-time generatin Quick Response Code, and two-dimensional code generation module generates Quick Response Code after dynamic two-dimension code
It is sent to display unit 50 by SPI interface and is shown evidence for payment to realize user or other vouchers.It can pass through
Campus informatization management platform sets the timeliness of the instant Quick Response Code, such as：5 seconds, if more than 5 seconds, the two of the in-time generatin
Code failure is tieed up, Quick Response Code is usurped to be effectively prevented by other people and causes unnecessary loss.
The working frequency of the attendance module is：13.56MHz, 2.4G,
User carries the electronic card 1 with 2.4G modules, when by way of attendance region, the attendance with 2.4G card reader
The machine-readable information for taking the card to send out, and campus informatization management platform is reported to carry out business processing, realize remote work attendance.
Wherein, 2.4G attendances module can be 2.4G single-frequency RFID modules.
Electronic card 1 has the bluetooth module being connected with main control unit 20, and bluetooth is utilized with mobile phone interaction, realizes electricity
Subcard piece is bound with system of account, and bluetooth is also to use extensive smart mobile phone standard configuration.
Conditional electronic card limits it due to the use of interactive mode and is promoted in wide range of areas.Since electronic card is most normal
It cannot be networked at any time with consumption scene, cause conditional electronic card that can only be traded data interaction using particular device.Once
It is detached from campus environment, these conditional electronic cards can not just use in the scene that no particular device is supported.
Fig. 3, Fig. 4 are please referred to, Fig. 3 is conditional electronic card transaction mode one, and part transaction data can be stored in traditional
Student, which takes, in raw card A, when transaction snaps into equipment for customizing bankcard consumption, and swiping card equipment B carries out transaction data exchange with card, then again
Data check is interacted with background server C, transaction, otherwise Fail Transaction are completed after being identified through.
Fig. 4 is conditional electronic card transaction mode two, and transaction data will not be stored in card, and student takes tradition to learn when transaction
The unique information that raw card A blocks to equipment for customizing bankcard consumption, swiping card equipment B acquisitions, then interacts with background server C again
Transaction data verifies, and transaction, otherwise Fail Transaction are completed after being identified through.
The goal of the invention of novel dynamic two-dimension code electronic card is exactly to solve the constraint of traditional student card.
1. usage scenario is more rich；
2. consuming details of use to be easier to grasp；
3. integrated mature technology consumer is more easily adapted to conform to.
Novel dynamic two-dimension code electronic card key technology feature is：
It not only supports attendance mode, also supports dynamic two-dimension code mode, adapted to the Quick Response Code of maximum consumption scene in this way
Barcode scanning consumes scene, has been also compatible with most Old style campus consumption habits；
Using MFA (Multi-Factor Authentication) token based on time uniqueness, account is increased in this way
Family safety；
With identification traditional highest weight is substituted with management IAM (Identity and Access Management) is accessed
Limit account, such advanced level user can set sub- account permission, limitation hold the consumption number of times of student, the single amount of money, total amount,
Classification etc. is consumed, as shown in Figure 5.
The smart mobile phone of bluetooth is supported to bind account.
Fig. 2 describes entire hardware frame, selects the main control chip of high integration, in this way periphery only need Bluetooth antenna,
RFID antenna, LCD and battery.
Implement the technical program can fingerprint recognition and dynamic two-dimension code electronic card, there is technique effect below：
The deficiency that middle dynamic two-dimension code does not enter into campus usage scenario is different from the prior art, the utility model can refer to
Line identifies and the electronic card of dynamic two-dimension code is realized using attendance module and is steadily compatible with existing campus use habit, increases newly simultaneously
Dynamic two-dimension code come adapt to School usage scenario (including barcode scanning consumption, trade confirmation, interaction confirm etc.).
The above is only the preferred embodiment of the utility model only, other being not intended to limit the utility model make
With case, any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention should all include
It is within the protection scope of the utility model.
