Abstract

In various embodiments, a smart card module is provided. The smart card module may include an electronic circuit in or on a carrier, a smart card module contact layer, which is coupled to the electronic circuit and provides a plurality of smart card module contacts, a mirror layer on the smart card module contact layer, said mirror layer at least partly covering the smart card module contacts, and an optically translucent, electrically conductive oxide layer, which covers the mirror layer. The optically translucent, electrically conductive oxide layer includes a plurality of regions of different layer thicknesses for providing different color components.
