Abstract:
1. A security element in the form of a flexible multilayer film body, comprising: a receiving unit for receiving an electromagnetic verification signal containing a specific coding from a verification device; an output unit for outputting an enable signal; and an electronic release system having active and/or passive organic components, wherein the electronic release system is configured to check whether or not a signal received by the receiving unit contains the specific coding, and drives the output unit for outputting the enable signal if the signal received by the receiving unit contains the specific coding, and in that the output unit has at least one electrochromic element, a thermochromic element, an electroluminescent element, an electrophoretic element, a liquid crystal element or an organic light emitting diode; wherein the electronic release system is further configured to check the signal received by the receiving unit in respect of the direction from which the signal impinges on the security element, and drives the output unit for outputting the enable signal if the signal received by the receiving unit impinges on the security element from a predetermined direction.
