Abstract
An access control system for controlling access to an enclosed area, the access control system comprising a radio-frequency communication module configured to receive a card identification signal, a mode module configured to determine an operational mode of the access control system, the operational modes including a standalone mode and a network mode, a communication module configured to authenticate the card identification signal by transmitting the card identification signal to an access control server when the access control system is determined to be operating in the network mode, a local authentication module configured to authenticate the card identification signal against entries of one or more internal tables stored in the access control system when the access control system is determined to be operating in the standalone mode, and a local input/output module configured to send a signal to unlock a door at an entrance to the enclosed area when the card identification signal has been successfully authenticated.
