The invention relates to a security element that is provided with a first co de 40 consisting of a magnetic material and/or a second code 30 consisting of a n electrically conductive material, in addition to a third, optically readable code 20, for instance in the form of a negative script and/or bar code, whic h is in the magnetic and/or electrically conductive code or is preferably produced together with a third neutral material 50, wherein the neutral material is neither electrically conductive nor magnetic. According to the invention, all three materials previously cited cannot be optically distinguished, i.e. viewed with the naked eye, by an observer and thereby appear as a uniform coating made of a single material. |
