Abstract
The card-format data medium (1, 1') has a substrate (S) with an upper and a lower surface (10, 11) and an encircling edge (10a). A transparent protection layer (6) and a security film (5) are applied to the top surface (10) of the substrate (S). The security film (5) is positioned within the top surface (10) of the substrate (S) and the transparent protection layer (6) projects beyond the security film (5) all the way around. In at least one peripheral area (6a, 6a'), the protection layer (6) is bonded directly to the substrate (S) over a wide area. The data medium (1, 1') is particularly resistant to environmental factors and secure against tampering and counterfeiting.
