<P>PROBLEM TO BE SOLVED: To carry out a stamp rally by using a communication device such as a cellular phone and an on-board terminal equipped with a GPS function or the like for constructing a stamp rally system greatly improved in convenience in comparison with a conventional one. <P>SOLUTION: This stamp rally system automatically makes a request for issue of a stamp when a terminal such as the cellular phone 208 and the on-board terminal carrying a GPS function 0201 and the like for detecting its own positional information determines that the terminal itself is within a stamp area. In this way, the positional information is specified very easily and accurately in comparison with a conventional system. When an entry for the stamp rally is made previously, the stamp can be issued since the terminal itself automatically requests issue of the stamp when the terminal enters the stamp area even if an entrant cannot operate the portable terminal he/she is at the wheel. <P>COPYRIGHT: (C)2007,JPO&INPIT |
