Basic definition of access card The original intelligent access control system consists of a host, a card reader and an electronic lock (computers and communication converters are added when networking). The card reader is a contactless card reader. Only when the cardholder quickly swings the card near the card reader (5- 15cm) can the card reader sense the card and guide the information (card number) in the card to the host.

The host computer examines the illegality of the card before deciding whether to close the door.
