Abstract

An apparatus and method for checking value documents, in particular bank notes, and a value-document processing system having at least one sensor for capturing an electromagnetic radiation. Transmitted by a value document and generating corresponding first sensor signals and for capturing an electromagnetic radiation remitted by the value document and generating corresponding second sensor signals, and an evaluation device for checking whether the value document has a foreign object. In particular adhesive tape, taking into account the first and second sensor signals which correspond to the electromagnetic radiation respectively transmitted or remitted in the region of the edge of the value document. The apparatus and method prevent a deformation in the region of the edge of a value document from being identified as a foreign object.
