Abstract
A method enables loading/unloading of a plurality of types of games as part of an application program, typically, a game application program installed on a smart card system with a high ability to store information for which highly-reliable security is achievable, extending the range of use of the card. Of a Program to run on the card, the processing parts that can be executed in common are packaged as modules and game definitions described in scripts are loaded/unloaded into/from the card as required from a terminal operating with the card. In the program, a script interpreter that interprets and executes scripts, a controller that controls the loading/unloading of scripts, a controller that performs the management of point data and rights to play a game are provided, whereby dynamic loading/unloading of types of games is possible and one application can offer a plurality of types of games that can be selectively executed.
