Why do smart communities use QR code access control?
In the era of data and information, it is destined to create a "Internet +" life, and more and more smart communities are beginning to apply QR code access control to actual projects. It solves the problem of difficulty in managing access control personnel and accessibility of visitors, and allows smart community properties to better manage the security of access control, and also improves user convenience and experience. Then we analyze the security and experience of the QR code access control. Why does the smart community choose the QR code for access control?
1. Security analysis from two-dimensional code access control
Two-dimensional code access control is a new section in the field of access control. The prototype of the development is to use static mobile devices to produce static two-dimensional code to open the door. However, from the perspective of security, the user finds that the static two-dimensional code is easy to be copied. If you take a screenshot or take a photo, you can open the door directly, and after the static QR code is shared, you can't find who the sharer is. You can't do real real-name system opening and back-door recording management. This is also the development of QR code access control. The problem is that because of its weak security performance, it cannot be promoted, and the QR code access control is constantly upgraded. Therefore, in order to improve security, the development of dynamic two-dimensional code access control has been started, and the security has been greatly improved.
The dynamic two-dimensional code access control generates an encrypted dynamic two-dimensional code by hand ji number/card number+time. After the two-dimensional code reader reads the dynamic two-dimensional code, the information is transmitted to the controller, and the controller analyzes whether the information is legal. And decrypt, decrypt the information to the relay, the relay controls the door lock to open the door. If the information is not legal, the controller will return the information to the card reader, displaying the red indicator light, and some models do not prompt or open the door.
2. User experience analysis from two-dimensional code access control
The needs of users are the first driving force for product development. There are various types of domestic communities. In order to provide users with a high-end experience, many smart communities have installed two-dimensional code access control, and considering the special characteristics of the crowd, most of the community personnel There are young people, old people, children, so the QR code can not only use the QR code to open the door, but also use the old card, student card, password to open the door, (that is, IC card, CPU card, identity zheng, etc.) Sexuality or convenience, the experience of QR code access control is good.
3. Analysis of the installation aspect of the two-dimensional code access control
The Sebres QR code can be supported by an external plug-in type, and can be mounted on a glass door, wall, etc. The appearance is 115*75*22mm small and exquisite, easy to install, and the two-dimensional code access control of the Seberus YT05 series is read. The card unit is integrated with the controller and is easy to install, eliminating the need to install an additional access controller.
4. Analysis from the aspect of cost performance
Sebrus QR code access control two-dimensional code, IC card, CPU card, NFC, password keyboard, etc., a number of functions, can save procurement costs, and a lot of experience.
