KEY CARD OPERATED SECURITY AND ACCOUNTABILITY SYSTEM

摘要

A logic controlled security and accountability system. An area to be secured is locked by an electrically actuated lock. A coded program card is inserted into the lock control apparatus and programs it to respond only to a predetermined code. When an authorized person desires access, he inserts into the lock control apparatus a key card coded with that predetermined code to cause an actuating signal to be applied to the lock. The program and key cards can be made of an inexpensive material and coded individually for each successive guest, and so if the system is installed in a hotel, for example, no loss is experienced and security is not jeopardized should a guest fail to return his key card when he checks out. Additionally, in a hotel or similar facility utilizing the system in conjunction with a computerized billing system, once a guest has inserted his program card into the lock control apparatus associated with his room, his key card can be used in shops within the hotel to charge purchases to the account of his room.
