<p><P>PROBLEM TO BE SOLVED: To provide an entry/exit management system and an entry/exit management method which have high precision. <P>SOLUTION: The entry/exit management system includes antennas for receiving a signal from a radio IC tag, a receiver for transmitting the signal of the radio IC tag received by the antennas, and a server for storing the signal of the radio IC tag transmitted by the receiver, into a transaction database. The number of antennas installed in places which more radio IC tags enter/exit from per time period is larger than that installed in places which less radio IC tags enter/exit from per time period. Furthermore, the server stores entry/exit of a person corresponding to a radio IC tag, into the transaction database in response to detection of the signal of the radio IC tag in at least two places. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
