Abstract

PURPOSE: To prevent oxidation, corrosion and wear to eliminate malfunction or leak current by putting polarization filter that transmits only light with specified wavelength onto light receiving surface of a solar cell and by burying in the card by using a non-contact type I/O device like photo-coupler. CONSTITUTION: Interior of a card proper 1 made of synthetic resin, etc., has incorporated IC 2, to which an input part 3 and output part 4 have been connected through wiring 11 and 12 , respectively. Besides, capacitors or electrodes put on the input part 3 and the output part 4 have been coated with synthetic resin material composing the card so as not to be exposed directly on the surface of the card proper 1. Accordingly, input signal can be given to IC 2 within the card by bringing an electrode close to the input part 3 with an external unit to apply electric field, whereas output signal can be read by bringing a sensor to detect a change of electric field close to the output part 4. Further, the IC 2 is driven with source voltage supplied from power supplying part 5 like battery.
