A standardized access card is formed of a single or a pair of bonded sheets of 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.

A method of producing cards adapted to provide access to a system for processing electrical signals, comprising: providing a plurality of sheets, each having at least one cavity and being of a predetermined surface area and thickness and having associated contact positions adjacent said cavity, providing a plurality of integrated circuit assemblies each including a substrate having a surface area and a thickness substantially smaller than said predetermined surface area and thickness of said sheets and carrying at least one circuit device and an associated array of conductors, inserting each of said integrated circuit assemblies into a corresponding one of said cavities, and attaching the conductors of each of said assemblies to associated contact positions on the corresponding one of said sheets to thereby form said card for processing electrical signals.
