Chip card used as e.g. phone card or identity card, has an electrical conducting contact element arranged in contact micro-structures or nanostructures, with applications for communications and identification cards

摘要

Chip card comprises a support element (201), at least one electrical conducting element (202) in contact with a part of the surface of the support element and at least one electric circuit (203) on and/or in the support element and connected to the conducting element. It is arranged in the conducting element in contact with some micro-structures and/or nanostructures with a dimension such that the micro-structures and/or nanostructures absorb electromagnetic radiation of at least one wavelength. Independent claims are also included for : (a) production of this chip card; (b) an electrical conducting element arranged in some micro- structures and/or nanostructures.
