An intelligent card has a calculation function and a card holder collation function, and is formed to have the same size as that of a credit card. With the collation function, numeral data input from a key input section of the card is collated with identification data prestored in an internal integrated memory circuit. A so-called IC card itself is relatively expensive. However, the intelligent card of this invention additionally has a calculation function, and the IC card function can be provided inexpensively.
