发明名称 CHIP CARD WITH A CONTACT ZONE AND METHOD OF PRODUCING SUCH A CHIP CARD
摘要 <p>A chip card has a contact zone on which an electrically conductive lacquer applied. The electrically conductive lacquer is based on an intrinsically conductive plastic material. Pigments are added to the electrically conductive lacquer. In an alternative embodiment an electrically nonconductive lacquer is applied to the contact zone. Conductive particles are disposed in the electrically nonconductive lacquer. The electrically conductive lacquer forms a covering for the conductive particles. A method of lacquering a contact zone and a method of producing a chip card are also provided.</p>
