| 摘要 | The invention relates to a data storage card and to a method for the manufacture of a data storage card, particularly of a chip or magnetic strip card. The inventive storage card comprises a card body (1, 101, 201, 301, 401) comprising one or more films, wherein the film (2) or at least one of the films (2, 3, 4) is a coextruded film (2) comprising at least two regions with different material properties. The use of coextruded films makes it a simple matter to form various regions in the card body which differ from one another in terms of the nature of the materials. In particular, it is possible to form a data storage card with a card body comprising a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the face of the card body, for example. | ||||||
