ABSTRACT:
A card or badge is used for controlling access to facilities or facility areas which include remote card readers which are interconnected with a central card data processor. When access is requested at a remote location, a user inserts his card or badge into the remote terminal and the remote terminal sends data identifying the person to the central processor which, in turn, sends a command to the remote terminal to grant or deny access. When a card or badge is inserted into the system and no response is received within a predetermined time period, the remote terminal, on the assumption that communication line failure has occurred between the remote terminal and the central processor, reads a set of data from the user's card or badge to grant or deny facility access to the user on a secondary selection basis.
