1. The card reader uses dynamic QR code (valid time and usage times can be set) to prevent others from copying and stealing
2. It adopts international standard Wiegan 26/34 output, and can be directly connected to Wiegan interface access controller
3. After the user's mobile phone starts the WeChat applet, an ID card number (8 digits) will be automatically generated. The QR code for door opening generated by the user's WeChat applet is time effective
If the number of times is limited and encrypted, the card reader has no output and beep prompt after the QR code timeout or the number of times is exceeded
4. For the same WeChat applet, the ID card number output by the card reader will not change with the change of the QR code, but only once in the access control software (the ID number will not change)
5. It can identify QR code, IC card, mobile phone NFC, and other authentication methods
6. The two-dimension code reader adopts hard recognition, without networking, WIFI and data flow card. The mobile phone network is not required after the success of the applet,
The whole system does not depend on the network
