PROBLEM TO BE SOLVED: To provide a system for management of room entry/exit allowing another authentication medium to be easily used while maintaining security without requiring time and labor even when an authentication medium is lost.SOLUTION: When a non-contact key 6b is lost, a system for management of room entry/exit invalidates collectively all non-contact keys 6a to 6c belonging to a group to which the lost non-contact key 6a is given and makes a door control device 3, which controls operation of an automatic door 1A and an electric lock 2B, disable opening of a doorway of an entrance hall 1 by the invalidated non-contact keys 6a to 6c. The system for management of room entry/exit is equipped with a management server 9A which makes the non-contact keys 6a, 6b valid from the invalid state when a No. 101 room reader 5 reads identification codes of the non-contact key 6a, 6c authorized to enter the No. 101 room 2 in advance among identification codes 6a to 6c belonging to the invalidated group. |
