The utility model discloses an access control system, which belongs to the technical field of intelligent community management, and comprises an NFC radio frequency circuit, a microprocessor and an eID authentication decoding chip. The NFC radio frequency circuit is used for reading NFC equipment of a user so as to acquire NFC data of the user. And the eID authentication decoding chip is used fordecoding the NFC data of the user to obtain eID information of the user. The microprocessor is used for comparing the eID information of the user with user database information and sending a control electric signal to the electronic lock when the user database information contains the eID information of the user, and the electronic lock responds to the control electric signal to be unlocked. The eID information of the user is obtained from the NFC equipment of the user, the user information is verified according to the eID information so as to carry out on-off control on the electronic lock, and due to the fact that t
