Why is the QR code access control system widely used?

Now when you enter some communities, you will find that many communities will use the QR code access control system, and in some large factories, they may also use this system to manage the safety of the factory and the access of employees. Many people feel very puzzled. What are the advantages of this access control system? Why can it be widely used? Here is the reason for telling you!
First, scalability
For the two-dimensional code access control system, its compatibility and expandability are very important in the process of use, because for the community and the factory, they not only need to use this access control system, but also need to use the burglar alarm. System, building automation system, in addition to the need to use a full set of monitoring systems, etc., in order to be able to play a greater role, then this system needs to be combined, and for this access control system, Its scalability is sufficient, and the basic needs of various systems can be combined and used together with other systems!
QR code accessibility scalability
Second, high security
The reason why there are many communities and factories now, the management of personnel access is very strict, because if there are some idle people and other easy access to the community or the factory, then it is very likely that there will be theft or other insecurities. In this case, it is a serious threat to people's lives and work, and through the QR code access control system can improve its security, after opening the door, the QR code will be invalid, and later want to open the door again. A new QR code will be generated, so you can achieve higher security!
It can be seen that the two-dimensional code access control system does have many advantages, so he can get a wide range of applications, then in this case, you must definitely think deeply and see if you need to use this file. System, for the management of the factory or community, if necessary, it must be adopted in time!
