Problems solved by technology

Due to the enormous outlay, the problem also arises with the known methods that new types of counterfeit banknotes cannot be considered within a short time after their appearance, since the derivation and generation of the comparison data requires an extremely long period of time

Embodiment Construction

[0011] The banknote processing machine 10 has an input box 20 for inputting banknotes 21 to be processed, in which a separator 22 engages. The separator 22 withdraws the banknotes 21 to be processed one at a time and delivers the individual banknotes to a transport system 23 which transports the individual banknotes through the sensor device 30 . Features of each individual banknote are recorded in the sensor device 30 , which are important for determining the authenticity, type (currency, denomination), status, etc. of the banknote, for example. Such features can be detected mechanically, acoustically, optically, electrically and / or magnetically, for example. Known authenticity features include, for example, printed colors with special optical and / or magnetic properties, metallic or magnetic security threads, the use of whitener-free banknote paper, information contained in electrical circuits, etc. . The type of a bank note is determined by its size, printing pattern, colo...

Abstract

The invention relates to a bank note processing machine and to a method for identifying forged bank notes. According to said method, the bank notes to be verified are compared with comparison data that is derived from genuine bank notes and known forgeries, additional comparison data being used for recent forgeries. The bank notes to be verified are then compared both with the comparison data and the additional comparison data for recent forgeries in order to determine the existence of a forged bank note.

Description

technical field [0001] The invention relates to a banknote processing machine and a method for identifying counterfeit banknotes. Background technique [0002] Banknote processing machines are used to perform checks on characteristics of banknotes such as authenticity, condition, type of banknote. Depending on the result of the check, banknotes can be accepted, sorted, deposited, destroyed, etc., for example. Here, the identification of counterfeit banknotes is of particular significance. In order to identify banknotes and to distinguish genuine banknotes from counterfeit banknotes, criteria or comparison data are usually derived from the genuine banknotes, which allow identification of the individual banknotes with respect to currency and denomination as well as their authenticity. If a counterfeit is known for a particular banknote (ie a particular denomination of a particular currency), this counterfeit is also used to derive comparison data. For this purpose, real and...
