As one kind of access control product s , the access control ler plays an important role in the workplace, family and self-service bank. The machine integrates the card reader and the controller into one, and the installation and operation are simple and cost saving, which has won the favor of many merchants and users. There is no doubt about the technology and safety of technology. Biometrics such as fingerprint recognition, face recognition, iris recognition and vein recognition are gradually approaching people. 1. Key technologies of access contro ller From the understanding of the mainstream access control manufacturers, the main technolog ies of access controller include communication way, identification method, the recognition speed, storage capacity, record keeping time, working voltage, working current, output current. In this way, the progress of communication methods and recognition methods represents the development of access controller . 2. Biometr
