Under the orientation of a value document, a rectangular value document will be understood below to mean one of the four possible positions which can be obtained by rotating the value document around its longitudinal and transverse axes by 180 °. Depending on the classification, the value documents can then be sorted, for example, and if necessary the output areas are stored. This is explained using the example of value documents in the form of banknotes.
