Abstract
An IC card system for a game machine using an IC card includes a game token input device for inputting a game token onto the IC card based on the amount of money deposited. The IC card system also includes a game device that decreases the number of game tokens stored on the IC card when the IC card is used with the game device. The IC system also includes a totaling device that determines the number of tokens inputted by the game token input device and the number of tokens used by the game devices, at a particular location.
