Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1 and Fig. 2, the embodiments of the present invention, it is a kind of can barcode scanning payment electronic card 1, including shell
10, main control unit 20, Bluetooth antenna 40, security module.
Security module includes all kinds of symmetrically or non-symmetrically enciphering and deciphering algorithm modules and secure data access space.
Main control unit 20 connects power supply unit, is set in shell 10, Bluetooth antenna 40 is connected with main control unit 20, shell
Display unit 50 for showing dynamic payment code is set on body 10, and display unit 50 is connected with main control unit 20.
Main control unit 20 connects two dimensional code (or bar code) generation module, display unit by SPI interface.
It can also be with highly integrated two-dimensional code generation module in main control unit 20.
The product type of two-dimensional code generation module can are as follows: STM3280C51;
The product type of security module can are as follows: ASO1-ML01DP5;
The product type that main control unit 20 uses can are as follows: nrf52832.
The above chip is common chip and has auxiliary circuit, therefore working principle and process repeat no more.
Display unit 50 is set to the upper 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 payment code is shown, such as: a button in button 60.LCD two-dimensional code display (or bar shaped
Code), usually show that screen will not be lit, just can be lit simultaneously two-dimensional code display (or bar shaped when pressing using button 60
Code) pattern.
As shown in Fig. 2, the modules such as power supply unit, Bluetooth antenna 40, security module, display unit 50 and button 60 pass through
SPI interface is connected with main control unit 20.
Display unit 50 includes LCD display.
The generally rectangular configuration of shell 10.
LCD display is rectangular configuration.
The working principle of this product are as follows: the ID of two dimensional code (or bar code) generation module and card be binding, press by
Button, main control unit 20 have received information, and the instruction for generating payment data is issued to security module, and security module generates payment data
Transfer data to main control unit immediately afterwards, main control unit issues in-time generatin two dimension to two dimensional code (or bar code) generation module
The instruction of code (or bar code), two dimensional code (or bar code) generation module in-time generatin dynamic payment code are simultaneously transferred to master control list
Member, main control unit sends display unit 50 by SPI interface for two dimensional code (or bar code) and shows, after user's barcode scanning,
Using payment data as the evidence for payment of user or other vouchers after service platform decryption.
Different buttons is pressed, different payment datas is extracted, generates different two dimensional codes (or bar code), businessman's barcode scanning
Afterwards, service platform decrypts the evidence for payment of two dimensional code (or bar code) information as user.
The timeliness of the instant two dimensional code (or bar code) can be set by service platform, such as: 5 seconds, if more than 5
Second, two dimensional code (or bar code) failure of the in-time generatin usurps two dimensional code (or bar code) by other people to be effectively prevented
Cause unnecessary loss.
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.Bluetooth is also using extensive smart phone standard configuration.
Conditional electronic card is promoted due to using interactive mode to limit it 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 carry out transaction data interaction using particular device.Once
It is detached from campus environment, these conditional electronic cards are not just available in the scene that no particular device is supported.
The goal of the invention of novel dynamic payment code electronic card is exactly the constraint in order to solve conditional electronic card.
1. usage scenario is richer;
2. consuming details of use to be easier to grasp;
3. integrated mature technology consumer is more easily adapted to conform to.
Novel dynamic payment code electronic card key technology feature is:
It supports dynamic payment code mode, has adapted to the two dimensional code barcode scanning consumption scene of maximum consumption scene in this way, be 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;
The smart phone of bluetooth is supported to bind account.
The following figure describes entire hardware frame, selects the main control chip of high integration, in this way periphery only need security module,
Bluetooth antenna, LCD and battery.
Payment code generating algorithm can also concentrate on running on master chip.
Implement the electronic card with dynamic payment code of the technical program, there is technical effect below:
The deficiency that middle dynamic payment code does not enter into campus usage scenario is different from the prior art, the utility model has
The electronic card of multiple dynamic payment codes has multiple dynamic payment code generating algorithms to adapt to the usage scenario (packet of School
Include barcode scanning consumption 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.
