Abstract
An IC card used for identifying an individual, has a key pad on the surface, a memory for storing a program and data, and a planar microphone and speaker. Speech corresponding to data or a command is converted into signals by a microphone. These signals can be supplied to an output terminal of the IC card under control of the IC card. Alternatively, the IC card can store or analyze the speech and generate a corresponding command or data. As the number of functions of the IC card is increased, the number of commands must also be increased. By inputting commands or data by voice instead of dedicated function keys, the number of necessary keys is reduced and convenience is enhanced.
