Abstract
Abstract Premium point services offered by different retailers require each user to possess a plurality of cards for dealing with different applications. An electronic pocketbook system made of a display device and an IC card is provided to store diverse kinds of application information such as amount information and point information into a single IC card. Portions of the application information to be displayed are stored in a predetermined format into a predetermined area inside the IC card. This allows the same program of the display device to display various kinds of application information successively using a common program, and without having to an application specific program.
