The invention relates to a data carrier card and to a method for producing a data carrier card, in particular a chip card or magnetic stripe card. The data carrier card according to the invention comprises a card body (1, 101, 201, 301, 401) comprising one or several foils, whereby the foil (2) or at least one of the foils (2, 3, 4) is a coextruded foil (2) comprising 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 comprising a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the surface of the card body.

L'invention concerne une carte de stockage de données ainsi qu'un procédé de fabrication d'une carte de stockage de données, en particulier d'une carte à puce ou à piste magnétique. La carte de stockage de données selon l'invention comprend un corps (1, 101, 201, 301, 401) constitué d'une ou de plusieurs feuilles, la feuille (2) ou au moins une des feuilles (2, 3, 4) étant une feuille coextrudée (2) comportant au moins deux zones à propriétés de matériau différentes. L'utilisation de feuilles coextrudées permet de réaliser dans le corps de la carte, d'une manière simple, des zones différentes se distinguant par la nature de leur matériau. En particulier, l'invention permet de réaliser, par exemple, une carte de stockage de données comportant un corps constitué d'une alternance de bandes et/ou de bandes à fenêtres opaques et transmettant la lumière et/ou de fenêtres incorporées dans la surface du corps de la carte.
