The invention relates to a value document, especially a credit card, an identity card, or a ticket, and a transfer film for producing a value document. One of the surfaces of the inventive value document comprises a security element (2) which is provided with a magnetic layer (25) for storing machine readable data and a reflective, non-magnetizable metal layer (23). The metal layer (23) is disposed above the magnetic layer (25) in relation to the surface of the value document. The metal layer and the magnetic layer overlap at least in some areas. The area of the metal layer (23) that overlaps the magnetic layer (25) is subdivided into at least two zones (231) which are galvanically isolated from each other.
