Chip card contg. chip module embedded in card having at least two metallisation areas

摘要

Card for use as telephone card, bank card etc. mounts a chip module (2) with a structured metallisation forming contact area in /- 2 areas (20*. 20**), such that the outer, visible layer is of different metals and/or metal alloys with different light reflection and absorption characteristics. Also claimed is a method of mfg. a chip card from a plastic substrate on which a basis metallisation, pref. of laminated Cu, is applied by electrodeposition, the different areas being formed with the aid of selective blanking off.
