Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an entering/leaving management system capable of suppressing an owner of a recording medium in which identification information is stored from entering an entering restriction area by tailgating, and preventing the owner of the recording medium who has entered the entering restriction area by tailgating from being confined therein.SOLUTION: In a processor 52 of a data center 50, an entering history updating part 52a leaves the history of entering with an authentication code (identification information) read by a card reader 10, and deletes the history of entering on the basis of the fact that the authentication code has been read by a card reader 20, and a tailgating entering frequency counting part 52b counts frequency (tailgating entering frequency) when the authentication code has been read by the card reader 20 in a state that the history of entering with the authentication code it not left, and a tailgating entering frequency determination part 52c determines whether or not the tailgating entering frequency has reached an upper limit frequency, and an invalidation processing part 52e invalidates the authentication code after an electric lock 4 is unlocked as long as the tailgating entering frequency has reached the upper limit frequency.
