ABSTRACT:
An entering/leaving control system for a user who is carrying a wireless medium which stores at least collating information and has a wireless communication function. The entering/leaving control system includes a receiving unit provided near a gate for entering/leaving a specified place. The receiving unit receives the collating information transmitted from the wireless medium. A collating unit collates the collating information received by the receiving unit with preset collating information. An intention detecting unit detects a specified place entering/leaving intention of a user who is carrying the wireless medium. A judging unit judges entering/leaving authorization to enter or leave the specified place based on the output of a collation intention detecting unit and the result of the collating unit. A control unit controls the opening/closing of the gate based on the output of the judging unit.
