Abstract

Abstract A key input unit, a display unit and a solar cell are arranged on one surface of a card-like electronic calculator. This surface serves as an electronic calculator. The outer shape of the card-like electronic calculator is the same as that of a credit card. Furthermore, a magnetic stripe portion on which predetermined data is recorded, and embossed portions for displaying information are formed on the other surface of the calculator. Therefore, the calculator also serves as a credit card.
