Time backgroud
Traditional access control is the use of IC / ID card or password as the access control verification, some older communities are using this type of access control, this type of access control has a number of shortcomings, the following are the shortcomings of traditional access control:
1. Security is not strong:
If the password is used to open the door, there will be a problem that the password is sneaked, resulting in password leakage. This type of problem will occur when the password is used to open the door. When the IC/ID card is used to open the door, the access card is easily copied. The problem is that when the street shop spends a dozen dollars, a copy of the access card comes out, and the copied access card is generally the same as the usual access card, and the access control can be opened normally.
2. Insufficient convenience:
If you haven’t experienced the forgotten access control card, you will not be able to talk about it when you come back. Although this sentence is a bit exaggerated, it tells the pain points experienced by many people. When I go out and forget the access control card, many people have experienced it. This shows that the access control card is used to open the door and the convenience is poor. Although the access control of the password is convenient, it is convenient to sacrifice the security, and it is not worth the candle.
3. No guest system:
When there is a visitor, whether it is the access control of the access control card or the access control of the password, the visitor does not do very well. The interview with the intercom can also open the door to the visitor at home, some older access control. Without the intercom function, you need to go downstairs to open the door for the visitor, which is very troublesome.
solution
In building a smart community, residents have higher requirements for living experience, and traditional access control cannot be met. In recent years, QR codes have been applied to different levels in various industries, and the access control industry is no exception. Two-dimensional code access control came into being. Can the two-dimensional code access meet the requirements of building a smart community? Can the two-dimensional code accessibility solve the shortcomings of traditional access control? Let's take a look.
Safety
The Sebrus QR code access control uses a dynamic two-dimensional code. The two-dimensional code changes with time. It does not have the security problem of being leaked or copied like the traditional access control. The QR code is even screened or Photographing is useless, the QR code will change all the time, and the security is greatly improved compared with the traditional access control.
2. Convenient
Modern people go out, you can forget to bring your wallet access card, etc., but you will never forget to bring your mobile phone. Weixin is also an app that must be installed by modern people. The Seberus QR code can be used with the Weixin small program. You don't need to install APP. It will not occupy the storage space of the mobile phone, which is convenient and quick.
3. Visitors
The two-dimensional code access control is much better than the traditional access control in the visitor field. The Seberus QR code access can directly generate the two-dimensional code with the number of times and time directly in the Weixin applet, and then the two-dimensional code generated by the resident will be generated. For visitors, visitors can go through the QR code directly, without requiring the residents to open the door. Moreover, if the generated QR code is used more than the set number of times or time, it will automatically fail, and there is no need to worry about the security problem of leakage.
