Claim:
A device for handling banknotes, having an input and output unit to deposit and disburse banknotes, said device comprising: a control unit, at least one money cassette for storing banknotes, a reject cassette to receive banknotes to be retained, and a transport unit to transport the banknotes between the input and output unit, the money cassette and the reject cassette, wherein a stock counter is provided that indicates the current quantity of banknotes for the money cassette, wherein when a banknote is removed from the money cassette the control unit reduces the value of the stock counter by the value one and when a banknote is brought to the money cassette said control unit increases the value of the stock counter by the value one, wherein when an incorrect withdrawal occurs after at least one banknote is removed from the money cassette, the control unit activates the transport unit in such manner that said transport unit transports the banknote, or banknotes, from the incorrect withdrawal to the reject cassette, and wherein a money cassette-specific reject counter, explicitly assigned to the money cassette, is provided that indicates the total number of banknotes removed from this money cassette and taken to the reject cassette, and wherein the control unit increases the value of this reject counter by the number of banknotes transported to the reject cassette by reason of the incorrect withdrawal, wherein a virtual auxiliary cassette to which a stock counter is assigned is located in software of the control unit, and that the control unit increases the value of the stock counter of the virtual auxiliary cassette by the value of the reject counter of the money cassette when the money cassette is removed from the device.
