Abstract: The invention relates to a fingerprint recognition module comprising a substrate consisting of a material that is electrically insulating at least on its upper side and at least partially thermally insulating. Said substrate receives a composite of structured thin films on its surface, which directly forms a measuring field on the surface of the substrate for measuring a fingerprint. Said composite consists of an array of resistive, temperature-dependent elements, and contains strip conductors which connect the resistive, temperature-dependent elements to at least one connection field located on the substrate, outside the measuring field, and form part of the composite of structured thin films.
