QR code access control unlocking principle

With the popularization of QR code access control applications, residential areas, office buildings and other places now need to be identified by access control to enter and exit. During the evolution of access control equipment, the most we have come into contact with are mechanical locks or stand-alone access control, face And fingerprint access control also appears in our lives from time to time, as an emerging access control-QR code access control has also attracted more and more attention. How is QR code access control used? I believe that many users are still not clear.

Composition structure of QR code access control

To understand how the QR code opens the door, you must understand what is needed to install the QR code access control. After understanding the basic framework of the QR code access control, you can replace or install the QR code according to the actual situation of the user. Access control, which can save the installation cost to a certain extent. The QR code access control system consists of QR code reader, access controller, software system, Weixin applet (APP), door magnetic lock, exit button, power supply, switch and power cord. In order to facilitate the docking, some two-dimensional code readers and access control controllers are integrated together, and a two-dimensional code access control integrated machine designed for docking with third-party software platforms has been developed. The specific framework is as follows:

How to open the QR code access control?

QR code access control can be changed in different ways due to its high expansibility. The paper QR code and electronic QR code can be opened at any time. Today, we will follow the Sebros QR code access control system Take YT05 as an example to explain:

Whether it is in a community or an office building, it will involve the access rights of fixed and visitor personnel. Members who live on the floor need to register their identities at the management office first, and use the mobile phone | number as the identity wei ID card to authorize Mobile phone|number is registered in the weixin applet "scan code access control", the applet will generate a dynamic two-dimensional code, fixed members only need to rely on the door code to enter and exit; and for temporary visitors' access problems, First of all, we must confirm the identity of the visitor, clarify the person responsible for the visitor, and share the temporary door-opening code with fixed members to enter and exit, which not only ensures the floor safety, but also greatly improves the efficiency of the visitor. The specific use of the applet can be found by searching for "scanning code access control", or contacting the customer service staff of Sebreros.

Advantages brought by QR code access control

Now more and more places have been replaced by QR code access control, mainly because this scanning system can bring greater convenience to everyone. Especially for the community, after using this access control will become more secure. Because every owner uses his own Weixin applet or the QR code on the mobile app to scan the code, he can break through such embarrassing situations as forgetting or losing. Afterwards, even if a friend comes to be a guest, the owner can directly send a two-dimensional code to enter, which can save a lot of disadvantages and reduce unnecessary troubles.

For major office buildings or office areas, the benefits of using this code scanning access control are even more. First of all, the staff can know the number of access control through the app terminal, so as to avoid the peak period. At the same time scan code access control is simple to install. It is easy to use and easy to maintain.

Now this kind of QR code access control is not only found in some big cities, but also more and more second and third tier cities are also commonly used. I believe that in the future, not only high-end residential areas or office areas, even those ordinary residential areas will also use this code scanning access control.
