1, the structure of the two-dimensional code access control system

How to open the QR code access control needs to know the architecture and composition of the QR code access control. The main hardware is: QR code card reader, access controller, software system, door magnetic lock, exit button, power supply, switch, power cord and so on. There is also a two-dimensional code access control integrated with the two-dimensional code reader and the access control controller, that is, an all-in-one machine, which can directly interface with the background system, and the Seberus YT05 can be used as a reference.

In fact, many people are now familiar with the two-dimensional code access control, because it is similar to Alipay's QR code or Weixin's QR code. Just swipe the area where you want to go in and out with a QR code to the door recognition terminal, and you can successfully open the door. It is very convenient to use, and there is no error, and the personal information of the visitor or the entrant can be accurately grasped.

3, the advantages of two-dimensional code access control

Now more and more places have been replaced with scanning code access control systems, mainly because this scanning code system can bring greater convenience to everyone. Especially for the community, it will become safer after using this kind of access control. Because each owner scans the code through his own small program or the QR code on the mobile app, it can break the embarrassing situation of forgetting to bring or losing. After that, even if a friend comes to be a guest, the owner can directly enter a QR code to enter, which can save a lot of drawbacks, and can also reduce unnecessary troubles.

For major office buildings or office areas, the benefits of using this code-based access control are even greater.

Easy to use and easy to maintain.

Nowadays, this kind of two-dimensional code access is not only appearing in some big cities, but more and more second- and third-tier cities are also in common use. I believe that in the future, not only high-end residential areas or office areas, even those ordinary communities will use this scan code access control.
