METHOD AND DEVICE FOR VERIFYING A SECURITY FEATURE WITH ELECTROPHYTOGRAPHY IN A DOCUMENT OF VALUE OR SECURITY USING ADDITIONAL LIGHT RADIATION

Abstract

The invention relates to a method for verifying an electroluminescent security feature (2) in a value and / or security document (3) comprising the following steps: Exciting the electroluminescent security feature (2) using an electrical excitation signal (8), detecting radiation emitted by the security feature (2) and generating an output signal (11), evaluating the output signal (11) and deriving a verification decision, and issuing the verification decision, wherein in addition, while the security element (2) is excited to detect the emitted radiation, the security element (2) is irradiated with light radiation (31) in the UV wavelength range. Furthermore, the invention relates to a device for verification.
