<p><P>PROBLEM TO BE SOLVED: To provide a terminal device which enables an information sender to send information only to another user's terminal existing in a specific region specified by the information sender. <P>SOLUTION: The terminal device 10 is provided with an information management DB 22 which stores an ID specifiable uniquely and imparted to information in advance and a potential value showing whether preset information is transferred in association with each other, and stores. A communication control part 24 receives from another terminal device, information, and an ID and potential value both corresponding to the information, and an information management part 23 registers the information, the ID, and the potential value into the information management DB 22. Then, the information management part 23 reads the potential value corresponding to the information from the information management device DB 22 and, when the potential value exceeds the predetermined threshold, the information, the ID corresponding to the information, and a value obtained by subtracting a first subtraction value from the read potential value are transferred to the other terminal device connected by radio. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
