The card reader reads the card identification number and instantly sends it to the access control field panel. The access control field panel verifies the card's validity and allows the user to enter or exit the door.

Besides entry/exit, the access field panel also transmits the valid access transaction record to the server computer to store that information securely.

If the card used by the user is duplicate or has expired, the access control field panel will reject the entry of the user. Access control can store transaction records of all invalid access attempts. The transaction record stores the name of the cardholder trying to enter the premises. Also, it stores information about the reason for rejecting the entry.
