Abstract

A card-like electronic apparatus includes a plurality of external contacts and input terminals. The apparatus further includes a memory for storing application data, a designating unit for designating the application as stored in the memory, and a display unit for displaying the designated application data. When a power control key provided on the side of a card apparatus is in an on state, the application can be changed to another application by the designating unit. The applications as designated are successively displayed by the display unit. Through this display, the application to be used at any given time can be specified.
