Abstract:
The invention relates to an apparatus and a method for automatically checking sheet-shaped documents of value.According to the present invention a simply constructed measuring apparatus can be obtained, by the measuring apparatus evaluating measuring values e.g. at least two measuring frequencies and the position of one or a plurality of discrete measuring tracks being determined in such a way that at least the presence of two different not visible spectral properties of a predetermined type of authentic documents of value can be checked.
