As a new modern security management system, access control system integrates automatic identification technology and computer control information management measures, involving electronics, machinery, optics, computer technology, communication technology, biotechnology and many other technologies. With the development of automatic identification technology, UHF RFID access control management system has become the main part of security system, which is widely used in many fields, such as industrial automation, commercial automation, transportation control and management. Access control system based on RFID technology is the development direction of access control system construction in the future.

The personnel access control and attendance management system integrates UHF RFID technology, image recognition technology, network technology, video capture technology and other technologies to realize the integration of enterprise employee access control and attendance management and digital management. The system has the function of intelligent photo comparison. The system captures and stores the images of personnel swiping cards through image acquisition equipment and compares them with the system database photos, The successful elimination of the phenomenon of employee swiping card provides the most reliable data support for the enterprise's reasonable attendance management, and maximizes the enterprise's access safety supervision.

UHF RFID access control management system is composed of access control machine (integrated with reader and controller), identification card, computer and electromagnetic lock. Generally, there are two forms of access control system. One is that when employees pass through the access control system, they only need to point their cards (UHF RFID electronic tags) at the infrared rays of the access control machine, and the door will open automatically. The other is UHF RFID UHF remote access control management system. Through the installation of UHF reader and UHF electronic tag worn by employees, the door opening and closing, and the reading of ID card can be fully intelligent and automatic in the whole process of passing, without workers' operation, saving time. The cost of the second kind of UHF RFID access control management system is high, and the choice of these two forms depends on the specific needs of enterprises.
