What is the formation of the QR code in the end?

The two-dimensional code access control is based on the Internet as the technology. Through the Internet and cloud computing technology, the data flow and information management of the personnel flow and movement track in the access control system are realized.

The two-dimensional code adopted by the two-dimensional code access control system is used as the media for personal identification. Each user is assigned a specially encrypted two-dimensional code in the management system. The user can scan the two-dimensional code by using the two-dimensional code access control card reader. You can open the corresponding access control. The user can also share the visitor aging QR code through the social software to the visitor, and the visitor can independently scan the QR code to open the door. Virtual replacement of traditional access cards with mobile communication tools is both environmentally friendly and safe.

The QR code access control system is a new access control solution. From the beginning of the development of the QR code access control products, it is not difficult to find that the QR code is easy to be copied due to the static generated QR code. It is possible to open the door directly, and it is impossible to make a real real name system and open door record query, which has become a bottleneck in the development of early two-dimensional code, so its security is also criticized. The two-dimensional code access control has been continuously improved and optimized. At this time, a dynamic type of two-dimensional code access control has emerged to solve this security problem, which is safer than static in terms of security.

The user experience is the source of its development. There are many types of community in China. For some communities with good property management, if each building is equipped with two-dimensional code access control, not only can it be managed in a unified manner, but also the data of each building can be centralized. Said, not only can go out without access control card, just need a mobile phone to return to their home, it is very convenient.

Two-dimensional code access control in the current market, there are 86 boxes of two-dimensional code access control devices, there are also external two-dimensional code access control, but 86 boxes of such devices need to be excavated or to be opened, manufacturers not only do not need to make major modifications, Can be replaced with two-dimensional code access control, so the external two-dimensional code access control is relatively more convenient, micro-transformation. It is also convenient for the engineering company to save the project cost, and also facilitate the replacement of the later products, and also facilitate the maintenance of the project.

Nowadays, in the development of two-dimensional code access control, it can not only use the two-dimensional code to swipe the card, but also can increase the coil through its own characteristics, so that it can recognize the identification function such as the IC card, which is beneficial to keep the original card of the user usable. Add QR code to identify the door open, if you add a high-end access controller, you can achieve network management operations.

The application prospects of future QR code access control are also expanding. We have seen that in the high-end office buildings have begun to realize the two-dimensional code entry, the subway two-dimensional code gates continue to show the application prospects of two-dimensional code access control. This proves that its user experience is beginning to become popular.
