Abstract
The invention concerns a security element (10) for RF identification, and a security document which is provided with such a security element (10). The security element has a flexible film body (104) into which are integrated an electronic circuit which is designed for the storage of security-relevant items of information and an RF antenna which is connected to the electronic circuit and which serves for contact-less communication of the electronic circuit with a test device. Permanently fixed on a surface of the flexible film body (104) is a first optically variable element (102) which at least region-wise covers the region of the flexible film body in which the electronic circuit is arranged, wherein permanently fixed on the other opposite surface of the flexible film body is a second optically variable element.
