ABSTRACT:
A chip card comprises a chip card body, a chip, and a connector. The connector has a metal contact which is electrically connected to the chip for communicating electrical signals. The metal contact includes a main layer which is free of etched information elements, and a coating layer which has information elements etched therein. In one improvement, the information elements are laser-etched. In another improvement, the information elements are also marked on the chip card body and are stored in the chip. The present invention advantageously helps protect against the fraudulent interchanging of the chip card micromodule, including the chip and the connector.
