Abstract
Cards, labels and the like containing embedded microcircuits or other elements are fabricated in a continuous process by introducing microcircuits between ribbons of extruded material, pressing the ribbons into adhesion with each other while in a plastic state thereby to make a continuous composite sheet containing the microcircuits, cooling the composite sheet to solidify the extrudate material, and cutting out cards from the composite sheet, each card containing a microcircuit. The microcircuits may be introduced between the extruded ribbons on a continuous carrier sheet which may also serve as a printed circuit substrate for the microcircuits. Alternatively, the microcircuits are inserted as discrete units between the extruded ribbons by a suitable robotic device.
