ABSTRACT:
An IC card has a preregistered password and a display section which displays numerals and a cursor. An operator enters a password by moving the cursor to the desired numeral and presses a key. Fewer keys are thus required to enter passwords and the surface area of the card can be utilized more efficiently than if use is made of the usual set of ten number keys.
