Mobile phone access control products have been introduced in China. In recent years, the mobile phone access control industry has entered a stage of rapid development. The two-dimensional code access control system is the most popular way to open the door in mobile phone access. It has the function of replacing the card, and has unique visitor access function and high safety factor. It is widely used in office buildings, living quarters, joint office, gymnasium, etc. . In the past, it was more troublesome to bring a card. Now the mobile phone is basically a must-have for everyone. It is convenient and not easy to forget to use the mobile phone to sweep the door.
First, the introduction of two-dimensional code access control system
1. Access management, effectively preventing foreign casual people from entering the normal office order;
2. Permission control, which can conveniently and flexibly arrange the personnel's authority and door opening time for each access control, and strictly control the activity area and time of the personnel;
3. Real-time monitoring, monitoring personnel access and exit, greatly improving safety and management level;
4. Enhance the corporate image, which can reflect the company's management level and achieve corporate brand promotion;
5. The transformation of the media, relying on mobile phones as access control, away from the traditional bunch of keys and cards;
6. Realize "Internet +", which can realize the integration of online and offline access control operations.
7. It won't be lost like a traditional access card, forgot to bring it, suddenly you can't find it and forget it.
Second, the two-dimensional code access control system features
1. Dimensional Scanning Card Reader: Scans and recognizes the content of the QR code through optical principle, and integrates the IC or ID card reader to identify the built-in encryption card number of the sensor card through the principle of RF sensing.
2, dimension code: high-density coding, large information capacity (1850 letters, 2710 digits, 1108 bytes, 500 Chinese characters) is several times higher than the ordinary barcode information, and the coding range is wide (picture, sound, text, signature, Fingerprint), super fault-tolerant function (perforation, lossless, 50% of damaged area can still recover information), high decoding reliability (bit error rate does not exceed one ten-thousandth of a million)
3. Forbidden controller: store sensor card authority and card record, and centrally process all card reader upload signals, coordinate with computer communication and other data storage, and cooperate with the intelligent processing center of management software.
4, electric lock: electric actuator.
5. Management software: centrally manage and monitor all units through the computer, and perform corresponding clock, authorization, and statistical management.
6, open the door button: go out can be set to press the button to go out.
7. Power supply: Provides power supply for the execution structure of the system operating power supply and electric lock.
Third, the realization of two-dimensional code access control
Each time the user uses it, just click on the APP or the applet to automatically display a 10-minute valid QR code, and then use this code to brush the code on the read head instead of the card. The QR code is dynamically generated, and it is not the same every time. It is not easy to copy. Even if the copy is time-limited, the security is extremely high.
When a guest visits, the user opens the QR code access control, sets the effective time and number of the QR code, and clicks to generate the QR code, which will refresh a QR code. After the user presses the QR code image, the user can select Send it to the guest's mobile phone with tools such as WeChat and QQ. It can also be sent to guests using a screen shot.
