The advantages of two-dimensional code access control
First, very convenient
For many people commuting by subway, when they are on the subway, most people will not buy tickets, but will choose to swipe their cards or brush their mobile phones. Now it is more advantageous to brush the mobile phone because Everyone will bring a mobile phone when they go out, but they don’t necessarily remember to bring the card, so if they have a mobile phone, they can easily enter the station. Even if they forget to bring the card, it doesn’t matter. The code-based access control system does provide great convenience for people. At the same time, it can also improve the operational efficiency of the subway. After all, the time spent in the station is relatively short!
Second, high security
Whether it is a residential subway station or a variety of offices, if you need to set up a certain access control system, you may have to use the card to enter these occasions, but if your IC card is lost, it will be picked up by others. When you don't have access to the door, others can easily enter these occasions, so there will be certain security risks, but the QR code access control system uses the form of dynamic QR code, so the QR code Information will not be stolen by others, and there will be no lost situation and more security!
It can be seen that the characteristics and advantages of the two-dimensional code access control system can indeed better meet the needs of people, and can provide protection for people's travel and safety.
