A smart card having a support element, at least one electrically conductive contact-making element in a surface area of the support element, and at least one electrical circuit, which is on and/or in the support element and is coupled to the at least one electrically conductive contact-making element. Microstructures and/or nanostructures are incorporated in the at least one electrically conductive contact-making element, of such a size that the microstructures and/or nanostructures absorb electromagnetic radiation at at least one wavelength.
