Background
At present, an access control technology based on a coded lock is widely adopted by enterprises, in the access control technology based on the coded lock, a password of the coded lock is written into a Radio Frequency Identification (RFID) card, and when a user brings the RFID card close to an induction area of the coded lock, the RFID card actively sends password data to the coded lock, so that the coded lock is unlocked. In the above access control scheme, the user needs to carry a dedicated RFID card (also referred to as a "door card") because the user needs to unlock the combination lock only by using the dedicated RFID card.
Among the existing access control systems, the most common access control systems all adopt card swiping access control systems. Compared with a fingerprint iris palm type biological identification access control system, the card swiping access control system has the advantages of low cost, convenience in management and the like; compared with a password access control system, the password access control system has the advantages of convenience in management, difficulty in leakage and the like.
