Abstract
An identity card, especially a credit card, having a picture section, which contains a photo of the card holder. In this section, pixels of different absorptions, especially the gray and black parts, are burned by a laser beam point-by-point into a surface layer and/or an intermediate layer located below a transparent surface layer of the identity card. In addition, a colored part is applied, particularly using the thermal transfer process, which covers the same area as the image. Security features can also be introduced into the image division.
