The registered authorised users can obtain their own authority by logging in the WeChat app/app with account and password, generate the QR code belonging to their own access authority, and then pass through the dynamic QR code machine by swiping the code. The dynamic QR code is generated in relation to time, and the code generated every second is different, preventing the use of copying and screenshots, etc. The information of the QR code is encrypted, and the algorithm uses AES128, preventing it from being cracked.The RFID access card can be used to realise the function of opening the door by the user's local swipe through the remote sending user/local addition of the user.
