PROBLEM TO BE SOLVED: To provide a game interlocking point system for executing a game on an IC card, which can be used together with a simple point system, where games are not carried out, and doesn't require a large change of a terminal in a shop and can limit the number of times which user can execute game in accordance with proceeds. SOLUTION: Point data managed by a point application are divided into two classification of 'pints before game execution' and 'points after game execution'. When points are given in the shop, they are added to points before game execution. Points before game execute are reduced by to execute a game, and points obtained by the game are added to points after execution. Consequently, it is unnecessary to change the terminal for the shop, even a user who doesn' t execute a game can normally exchange obtained points. The system operation side can prevent infinite circulation of points obtained by games by limiting the number of times of user's game execution. |
