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 that there is a card and guide the information (card number) in the card to the host. The host examines the illegality of the card before deciding whether to close the door.
As long as it is within the valid credit card category, all processes can realize the access control management function. The card reader is installed on the side wall of the door, which does not affect other work, and can be monitored with the computer in real time through the communication adapter (RS485) (all doors can be opened/closed through the computer, and the status of all doors can be viewed in real time).

It is necessary to add more cards to the owners from time to time to meet the needs of property management, such as access cards, production cards, access cards, parking cards and membership cards. It not only increases the management cost, but also increases the difficulty for each owner to manage everyone's cards, and sometimes even "more cards are harmful", so it is gradually eliminated.
