ABSTRACT:
A security element is equipped with first code of magnetic material and/or second code of electroconductive material and has in addition third, optically read-able code, for example as negative writing and/or as a bar code, which is present in the magnetic and/or electroconductive code or is produced preferably together with third, neutral material, the neutral material not being either electroconductive or magnetic. According to the invention it is provided that all three aforementioned materials are indistinguishable to the viewer optically, that is, with the naked eye, and therefore appear as a uniform coating made of a single material.
