Multi-user management access control system

The invention discloses a realization idea and a method of an access control system under a condition that multiple users have the same identity authority limit. The realization idea of the access control system mainly comprises an idea of combining IC (Integrated Circuit) card authentication and code authentication, a multi-user code verification method and a mechanism for configuring functions of a multi-user identity verification starting system. Through utilizing process methods, problems on safety, convenience and practicability in real life are solved. When an IC card is lost, the temporary safety of the system can be ensured, large influence on the users is avoided, and the lives of the users are greatly convenient. The multi-user management access control system disclosed by the invention is suitable for environments of dormitories, houses and the like, and has excellent application prospect.
