Abstract

An apparatus and method for classifying value documents includes least two sensor devices arranged to capture waves reflected on a front side and on a back side of a value document and to generate corresponding sensor data or to capture properties of the value document in at least two different regions of the value document by means of different measuring principles and to generate corresponding sensor data. At least one evaluation device is arranged to classify the value document with the aid of the sensor data generated by the at least two sensor devices, which sensor data relate to the waves reflected on the front side and back side of the value document or to the properties of the value document captured in the at least two different regions of the value document by means of different measuring principles.
