Data cards of the type used as bank, credit, telephone or insurance cards are produced in a continuous sequential process. The cards have embedded IC circuits with inductive communication coils that are located at specific positions. The process involves feeding strip material over rollers with location holes (25) defining positions of the cards on the carrier. Subsequent processes have the electronic modules (3) transferred from foil into a prepared aperture (33) formed on the card. Further operations include the winding of planar coils at the locations on the card. Protective resin material is overlaid in other stations (61,63,65).
