ABSTRACT:
A credit card type small thin rectangular IC card has a battery and an IC comprising a CPU, a ROM and a RAM mounted on a flexible printed circuit and bonded within an insulative plastic material. The printed circuit of the card has a plurality of electrode terminals exposed in a parallel array along at least one edge of the card which are adapted to engage contacts of a mating socket. The printed circuit terminals are manufactured by coating copper, nickel and gold over polyamide resin and squeeze finishing the leading edge. The mating socket comprises a general U-shaped frame having a U-shaped channel adapted to receive the IC card and having internal recessed contacts adapted to engage the terminals of the IC card. The contacts extend from an exterior surface of the frame for interconnection with the circuits of a mating device. Downwardly projecting portions thereof are bent at least twice in the portion penetrating the bottom of the frame.
