AbstractA standardized access card is formed of a single or a pair of bonded sheets f material including a cavity within which is disposed an integrated circuit assembly for processing electrical signals arranged within the card. The thickness of the assembly is relatively smaller than the thickness of the card and terminal areas of the assembly are accessible through cut-outs in the card which may be open or plugged with conductive material. The card may be formed in a continuous process from a plurality of strips of material which separately provide the card material, the integrated circuit assembly and a cover for the device of the circuit assembly.
