A data carrier card and a method for producing a data carrier card, in particular a chip card or magnetic stripe card. The data carrier card has a card body having one or several foils, where the foil or at least one of the foils is a coextruded foil having at least two areas with different material properties. The use of coextruded foils makes it possible to form in a simple manner different areas in the card body which differ from each other in material quality. In particular, it is possible to form for example a data carrier card with a card body having a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the surface of the card body.
