Abstract:
1. A method for providing independent verification of circulating bank notes by independently verifying the operation of a bank note processing device following processing of a plurality of bank notes, the device including a bank note transport path, at least one primary detector and primary detector controller for detecting or sensing at least one characteristic of a bank note being processed, the characteristic for use in bank note processing decisions, and a decision interval, the device having performed at least a subset of a fitness determination on the bank notes, the method steps comprising: obtaining primary bank note processing data representing at least one of the characteristics of the bank notes as provided by the device's primary detector; obtaining first independent bank note processing data from at least one independent bank note first detector or from at least one independent memory storage device in data communication therewith, wherein the at least one independent note first detector and the at least one independent memory storage device are each independent of the primary detector and the primary detector controller such that the operation of the at least one independent note first detector does not influence the bank note processing decisions of the primary detector controller, wherein the first independent bank note processing data represents at least one of the characteristics of the bank notes as provided by the device's primary detector; and comparing the primary bank note processing data with the first independent bank note processing data to verify or audit the primary detector operation.
