detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1 and FIG. 2 , an embodiment of the present invention, an attendance student card 1 having a dynamic two-dimensional code includes a housing 10 , a main control unit 20 , an RFID antenna 30 , a Bluetooth antenna 40 , and an attendance module.

The main control unit 20 is connected to the power supply unit. The power supply unit is disposed in the casing 10. The RFID antenna 30 and the Bluetooth antenna 40 are connected to the main control unit 20, and the display unit 50 for displaying the dynamic two-dimensional code is disposed on the casing 10. Unit 50 is coupled to main control unit 20.

The main control unit 20 connects the two-dimensional code generation module and the display unit 50 through an SPI interface.

It is also possible to highly integrate the two-dimensional code generation module in the main control unit 20.

The attendance student card 1 integrates the attendance module, which is a close-up attendance module: NFC module and/or long-distance attendance module: 2.4G module.

The product model of the QR code generation module can be: STM3280C51;

The product model of the 2.4G module can be: AS01-ML01DP5;

The product model of the NFC module can be: nrf52832;

The product model of the main control unit 20 can be: nrf52832.

The above chips are commonly used chips and have auxiliary circuits, so the working principle and process will not be described again.

The display unit 50 is disposed in the upper half of the housing 10. In the lower half of the housing 10, a starting component, such as a button 60, for activating the display of the dynamic two-dimensional code connected to the main control unit 20 is provided. The LCD displays the two-dimensional code, and the usual display screen is not illuminated until it is pressed and the two-dimensional code pattern is displayed.

The display unit 50 includes an LCD display.

The housing 10 has a rectangular structure as a whole.

The LCD display unit has a rectangular structure.

The RFID antenna 30, the Bluetooth antenna 40, the attendance module, the power supply module, and the button 60 in FIG. 2 are all connected to the main control unit 20 in the form of an SPI interface.

The working principle of the product is: the ID of the two-dimensional code generation module is bound to the ID of the user (such as a student). When the button 60 is pressed, the main control unit 20 receives the information and sends an instant QR code to the two-dimensional code generation module. After the two-dimensional code generating module generates the dynamic two-dimensional code, the two-dimensional code is sent to the display unit 50 through the SPI interface for display to implement the user's payment certificate or other credentials. The timeliness of the instant QR code can be set through the campus information management platform, for example: 5 seconds, if it exceeds 5 seconds, the instant generated QR code is invalid, thereby effectively preventing the use of the QR code by others. Loss.

The working frequency of the attendance module is: 13.56MHz, 2.4G,

The user carries the attendance student card 1 with the 2.4G module. When passing the attendance area, the attendance machine with the 2.4G card reader reads the information sent by the card and reports it to the campus information management platform for business processing to realize long-distance attendance. .

Among them, the 2.4G time attendance module can be a 2.4G single frequency RFID module.

The attendance student card 1 has a Bluetooth module connected to the main control unit 20, and utilizes Bluetooth to interact with the mobile phone to realize the binding of the attendance student card to the account system. Bluetooth is also a standard configuration of a widely used smartphone.

Traditional attendance student cards have limited their use in a wider range of areas due to the use of interactive methods. Because the most common consumption scenarios of the attendance student card can not be connected at any time, the traditional attendance student card can only use the specific device for transaction data interaction. Once out of the campus environment, these traditional time attendance student cards cannot be used without a specific device support.

Please refer to Figure 3 and Figure 4. Figure 3 shows the traditional attendance student card transaction method. Part of the transaction data will be stored in the traditional student card A. During the transaction, the student takes the card to the custom device to swipe the card, and the card-swapping device B and the card carry out the transaction data. Interchange, and then interact with the background server C to verify the data, confirm the completion of the transaction after the pass, otherwise the transaction fails.

Figure 4 is the traditional attendance student card transaction method 2, the transaction data will not be stored in the card, the student takes the traditional student card A to the custom device to swipe the card during the transaction, the card device B obtains the unique information of the card, and then with the background server C The transaction data is verified and the transaction is completed after confirmation, otherwise the transaction fails.

The purpose of the new dynamic QR code attendance student card is to solve the constraints of the traditional student card.

1. The usage scene is more abundant;

2. Consumer usage details are easier to master;

3. Integrating mature technology consumers are more likely to adapt.

The key technical features of the new dynamic QR code attendance student card are:

It not only supports the attendance mode, but also supports the dynamic QR code mode, which adapts to the consumption scene of the QR code of the largest consumption scene, and is compatible with most traditional campus consumption habits;

Adopting a time-uniquemable MFA (Multi-Factor Authentication) token, which increases account security;

Replace the traditional highest-rights account with IAM (Identity and Access Management), so that advanced users can set sub-account permissions, limit the number of credit card users, single amount, total amount, consumption category, etc. Figure 5 shows.

Bluetooth-enabled smartphones bind accounts.

Figure 2 depicts the entire hardware framework, using a highly integrated master chip, so that the periphery only requires a Bluetooth antenna, RFID antenna, LCD and battery.

The two-dimensional code generation algorithm can also be concentrated on the main chip, the main chip uses ARM Cotext-M4, the main frequency is 64MHz.

The above is only the preferred embodiment of the present invention, and is not intended to limit the other use cases of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are It should be included in the scope of protection of the present invention.
