Bank note processing machine and method for operating bank note processing machine

1. A bank note processing machine comprising:

sensors, a transport system including a singling unit and at least one stacking unit, an input/output device;

a control device with an associated memory which controls the elements of the bank note processing machine by means of software and/or data stored in the memory; and

an interface which makes it possible to couple memory systems of different kinds to the bank note processing machine in order to alter, supplement or replace the software and/or data stored in the memory;

wherein the memory system has a drive and a storage medium which are suitable for optical and/or magnetic recording;

wherein the transport system transports single bank notes singled by the singling unit along the sensors to the at least one stacking unit according to an evaluation of data obtained by the sensors by the control device; and

wherein data obtained in the bank note processing machine during operation are stored in the memory system.

2. The bank note processing machine according to claim 1 , wherein that the interface is a standardized interface, in particular according to PCMCIA.

3. The bank note processing machine according to claim 1 , wherein the memory has a nonvolatile area, and after coupling of the memory system to the interface the software and/or data stored in the memory system are stored in the nonvolatile area.

4. The bank note processing machine according claim 1 , wherein that the memory has a volatile area, and after coupling of the memory system to the interface the software and/or data stored in the memory system are stored in the volatile area.

5. The bank note processing machine according to claim 1 , wherein the software and/or data stored in the memory system are stored in encoded form, and the controller is set up to decode the encoded software and/or data.
