<P>PROBLEM TO BE SOLVED: To provide an information storage control system capable of effectively reducing communication traffic in acquiring attribute information corresponding to a radio identifier, from a database through a communication network, and to provide an information storage method. <P>SOLUTION: A radio identifier detecting means 201 of the information storage control system 100 detects the radio identifier transmitted from a radio tag 10 given to an object, and a detected radio identifier storage means 82 stores the detected radio identifier. A detection duration measuring means 310 measures the detection duration of the radio identifier based on the history of the stored radio identifier. An attribute information acquiring means 73 acquires attribute information corresponding to the detected radio identifier, and an attribute information cache control means 320 controls the storage operation of attribute information to an attribute information cache means 71 based on the detection duration. <P>COPYRIGHT: (C)2007,JPO&INPIT |
