NETWORK KEY CONTROL SYSTEM AND KEY CONTROL SERVER

PROBLEM TO BE SOLVED: To provide a rationalized key control operation system and an upgraded key application service system and improve safety against the illicit application of keys. SOLUTION: A key control system 1 is provided to control and keep keys used for various facilities including conference rooms, etc. This key control system 1 is connected with users' terminals such as those of a control server 4, a reception terminal 5, a personal computer 6, a portable telephone 7, etc. via a network 3. The control server 4 receives users' appointments with key applications or their changes via users' terminals such as reception terminals 5, personal computers 6 or portable telephones 7, etc. When a user borrows a key, the control server 4 releases the key control section in the key controller 1 from lock and lends the appointed key to the appointed user. When the key lending comes to an end, the control server 4 registers the end of key lending in the condition control section. It also sends a user having borrowed a key e-mail for confirming that he/she has borrowed the key from the mail control section. COPYRIGHT: (C)2005,JPO&NCIPI
