Abstract
The invention relates to a method for the automatic verification of the authenticity of a postage indicium that has a value indication and that has a luminescent area, whereby the postage indicium has been applied onto the surface of a mailpiece, and whereby the surface of the mailpiece is illuminated with light having wavelengths from a spectral region, then a first image of the surface of the mailpiece is taken with a camera system and this first image is evaluated regarding the place of the postage indicia applied onto the surface of the mailpiece, subsequently the postage indicium is irradiated with light having wavelengths from a second spectral region, whereby this light is capable of exciting the luminescence of the luminescent printing ink.
