Why can the access control button open the door, but can't swipe the card, and the system shows that the verification failed?

(1) The operator sets the access control as a rest day (all cards cannot be opened on rest days).

(2) The operator initializes the entrance guard or the controller executes the initialization command for other reasons.

(3) The current card reader is faulty.

(4) The controller and card reader can't work normally due to insufficient power supply (check whether the mains supply has been cut off and whether UPS works).

(5) There is something wrong with the electric control lock, which can't work normally.

All the above situations will lead to the failure of verification. Solution: Contact the information center for maintenance in time.
