Verfahren für den Nachweis der Herkunft von Banknoten

The invention relates to a method for verifying the origin of bank notes from an automatic teller. In the inventive method for verifying the origin of bank notes, in particular forgeries, from an automatic teller, data characterizing bank notes to be paid out or already paid out from a sensor device for checking the bank notes to be paid out or already paid out for authenticity and/or type and/or state are detected, the data of the bank notes to be paid out or already paid out are stored, check data are generated by means of the sensor device for each bank note whose origin is to be verified, whereby the check data of the bank note to be verified are compared with the stored data of the paid out bank notes and the paid out bank note is ascertained whose stored data have the greatest match to the check data of the bank note to be verified, and the verification of origin for the bank note to be verified from the automatic teller is regarded as furnished if the match exceeds a given threshold value.
