Today, QR code access control often appears in office buildings, gyms, communities, etc., and is widely used. Many people have realized the real convenience and speed. It only takes two seconds to open the door. It breaks the disadvantages of traditional access control. However, many people have some doubts about the security of the QR code access control. In fact, it is mainly because many people do not understand the principle of the QR code intelligent access control system.
1.The principle of two-dimensional code intelligent access control system
Installing a QR code smart access control does not mean that the traditional access control is to be removed directly. It is completely possible to embed a QR code access control card reader on a traditional gate machine, and then it can integrate the QR code automatic identification and data transmission performance, and then based on the Internet technology and QR code automatic identification technology, to ensure and upgrade Real-time data transmission and instruction transmission of the property management system and mobile phone QR code access control system.
The complete set of two-dimensional code access control system includes software and hardware. The software of Cyberbos two-dimensional code access control system includes applets, computer background software, and the hardware includes two-dimensional code readers and access control boards. Anyone who has contacted the QR code knows that the QR code is generated by software. The specific technology is a program instruction written by a development technician. It will not be described here in detail. The workflow is shown below:
The owner only needs to download an app terminal on the mobile phone, and then perform real-name authentication to obtain the access right of the mobile phone two-dimensional code access control. Therefore, the principle of mobile phone two-dimensional code access control is relatively simple, but it is safe and convenient.
2. Where is mobile QR code access control applicable?
At present, mobile phone QR code access control is constantly popular. Except for office areas, office buildings and residential areas that we are familiar with, it can be used in many places at the same time. For example, communities, campuses, hospitals, tourist attractions, hotels, banks, factories, machinery rooms, scientific research institutions, etc. can be used. Because the two-dimensional code access control technology is very advanced, it contains microcomputer automatic identification technology and modern security management measures, which also involves many new technologies such as machinery, optical computers, communications, electronics and so on. Therefore, although the principle of two-dimensional code access control is relatively simple, it can well solve entrance and exit security management.
The use of two-dimensional code intelligent access control has far exceeded the management of doorways and keys, and with the continuous updating of technology, it will gradually develop into a very complete access management system. This is in line with the trend of the times, and is also a product of technological advancement. I believe that the use of QR code access control will become as popular as the use of mobile phone to scan and pay.
