Residents must take the "access card" of the community gate, the "key" of the unit building gate and the "key" of their own gate when they go out. Whenever you forget your keychain, you must ask to help your family; Or when there are visitors, they need to register in the property office and confirm their identity, and then use the "access card" to enter the community... These are the disadvantages of the traditional community access control. With the development of Internet technology, many community access control has been achieved through the embedded QR code scanner module combined with access control device, and the deep integration of Internet plus property terminal has been achieved.
In fact, in many places with strict identity verification, such as community entrances and exits, property districts, office buildings, administrative halls, etc., access control is required through various QR codes. When the designated access control app is opened on the mobile phone, a specific QR code (variable) is generated, which is aimed at the "QR code scanner" of the all-in-one access control machine. After scanning the code, the data of the QR code is read, and the user can enter smoothly after successful identity verification. One person one code (variable QR Code: it can only be used within a limited time, and it will be invalid when it is used up). If it is a visitor, it needs to apply for the authorized "temporary visitor QR code" before it can pass the verification.
Specifically, this kind of access control method is to judge the identity of the entry personnel through the embedded mobile phone QR code reader, to avoid the entry of irrelevant personnel, and to record the event accurately and effectively. In the application of this industry, Shenzhen Rakinda Technology provides a variety of embedded QR code scanner module, embedded QR code reader, QR code embedded scanner, etc. to meet the needs of community access control applications.
