Development history of access control system

The entry and exit access control system, as its name suggests, is a system that controls the entrance and exit passages. It is based on traditional door locks. Traditional mechanical door locks are simply mechanical devices. No matter how rational the design of the structure is and how strong the material is, people can always open it by various means. The management of keys in many access routes (such as offices, hotel rooms) is cumbersome, and keys and personnel must be replaced with keys and lost keys. In order to solve these problems, there are electronic magnetic card locks and electronic code locks. The emergence of these two kinds of locks has improved people's degree of management of entrance and exit passages to a certain extent, and has made channel management into the electronic age, but with these two With the continuous application of electronic locks, their own defects are gradually exposed. The problem with magnetic card locks is that information is easily copied, wear between cards and card readers is large, the failure rate is high, and the safety factor is low. The problem with password locks is that passwords are easily leaked and cannot be checked. The safety factor is very low. At the same time, since most of the products in this period were assembled with the reading part (password input) and the control part and installed outside the door, it was easy for people to open the lock outdoors. The access control system of this period still remained in the early immature stage, so the access control system at that time was often called an electronic lock, and its application was not extensive.

In recent years, with the development of proximity card technology and biometrics technology, the access control system has undergone a leap-forward development, and it has entered a mature period. There are induction card access control systems, fingerprint access control systems, iris access control systems, and facial recognition access control systems. Disordered keyboard access control systems and other technical systems, which have their own specialties in terms of security, convenience, manageability, and so on, and the application areas of access control systems are becoming wider and wider.
