Abstract

The invention relates to an apparatus and a method for checking bank notes wherein measuring values of the bank note to be checked are obtained and a classification of the bank note is carried out by evaluation of the measuring values in a plurality of checking steps, whereby the classification distinguishes in particular at least the classification categories, counterfeit, suspect and genuine bank notes, or acceptable or redispensable, and a linkage of a plurality of measuring values is formed at least in one checking step for deciding whether the checked bank note corresponds to a given classification category and this linkage term is compared with a corresponding tolerance range during evaluation.
