IC card, terminal device and service management server

An IC card applicable to a point system, which issues merit points each having a value same as money depending on use of the IC card to purchase a product or service, comprising:

• an input/output interface for exchanging data through connection with a terminal;
• a memory for storing a plurality of application programs, an accumulated merit point value and other data;
• and
• a processor for executing the application programs,
• wherein the memory stores, as one of the application programs, a game application including:
• a first routine of preparing in the memory a game pattern to be used to judge a result of a game when the game is played by a user, said game pattern being prepared when the IC card is coupled with one of a plurality of shop terminals in association with the point system via the input/output interface to the memory;
• a second routine of displaying a game screen corresponding to the game pattern on a display of a user terminal which is independent from the shop terminals and coupled with the IC card via the input/output interface,
• a third routine of receiving user input data from the user terminal via the input/output interface, judging the result of a game corresponding to the game screen by evaluating the user input data based on the game pattern stored in the memory, and accumulating a game point value issued depending on the result of the game in the memory, and
• a fourth routine of invalidating the game pattern having been played by the user, and recording log data with respect to the game pattern which has been played,
• wherein the first routine always prepares a new game pattern different from that indicated by the log data.
