Abstract

A method for producing a portable data carrier by means of a continuous production method, in particular a roll-to-roll method, includes the step of processing at least one foil in the form of roll goods. The unrolled foil is coated with an adhesive at least partially on at least one side. Subsequently, the foil is scored along at least one fold edge on at least one side of the foil. The foil is then folded along the scored fold edge in exact register and bonded. For this purpose the foil is folded in the direction of the side that is coated with adhesive, wherein the side coated with adhesive is arranged on the opposite side of the foil which has at least one scored fold edge, along which the folding is effected. Finally, data carriers are punched out in exact register from the at least one folded and bonded foil.
