The main surface of the card base has a recess (12). The leading end of the substrate is wrapped around the base and onto the underside. An integrated circuit chip (24) is set into the recess and a cover element (26) is bonded to enclose it. The contact surfaces are spaced to each other and are formed on both sides of the substrate. ADVANTAGE - Simple construction with contact surfaces.de608621ChipkarteEmbedded integrated circuit chip smart card, e.g. for bank, identification card - has formed plastic base with recess into which chip is fitted in, and metal coated flexible substrate formed upon base.patent1996-19637739
