The working principle of QR code access control system

In recent years, with the popularization of mobile payment and the rapid development of Internet information technology, QR code access control systems have become one of the mainstreams in the access control security industry. This is mainly due to the fact that AI intelligence is now bringing people a good experience in all aspects. The QR code access control also brings a very good intelligent access experience. The higher the living standards of people, the greater the need for QR code access control. So what is the working principle of the QR code access Control System? How to achieve mobile phone code scanning access?

The working principle of the QR code access control system:

The QR code access control uses the very mature access control system technology on the market, combined with the function of the QR code in the smartphone Weixin app, without collecting fingerprints and other biological features. It is a very mature technology currently on the market, with a relatively high safety factor. Two-dimensional code access control uses other live code technology like payment, which encodes the user's personal information, usage rights, time, etc., and also performs layered encryption operations on the basis of live code technology to generate dynamic two-dimensional codes , The time system is automatically updated, that is to say, a QR code can only be used once or more than the time, the QR code must be refreshed before it can be used, to avoid the security risks caused by malicious screenshot QR code opening the door.

The working principle of the two-dimensional code access control system has another special place is the light environment that comes with the two-dimensional code. No matter whether the external light is strong or weak, black or bright, it will not affect it. As long as the phone has power, it can scan the code. Moreover, when scanning QR codes, the access control system has a very fast operation speed, and can complete the scanning and opening operations in a few seconds. Solve the trouble of modern people with access cards or keys.

Features of Cyberus dynamic QR code access control:

1. The Weixin applet generates a new dynamic QR code every 5 seconds;

2. The QR code can be shared with visitors via weixin one-click screenshot;

3. The shared QR code is valid in a short time, and the effective time can be customized;

4. The QR code opening permission can be set flexibly through the access control software: which mobile phone and which time period can open which door;

5. There will also be records and inquiries when the QR code is opened!

6. OLED display (can display time, QR code attributes, etc.).

7. Automatic time adjustment of the reading head.

8. The sharing code can be customized.

9. The legal signal of the controller can be returned (the Card icon turns green, and the legal card is displayed on the screen).

10. Support remote upgrade.

Seeing this, you must have a clear understanding of the working principle of the QR code access control system. Two-dimensional code access control is a new type of door lock, but it is a product obtained after in-depth research from multiple angles of safety and convenience. There may be some shortcomings, but its value is undeniable.
