Abstract
The invention relates to a method and device for checking the degree of soiling of bank notes. To this end, the bank notes are conveyed along a transport path and illuminated by at least one light source with visible light of the blue spectral range. The light reflected and/or emitted by the bank notes, and/or the light having penetrated the bank notes due to transmission, is detected by means of at least one sensor and evaluated.
