Abstract: A system and method for independently verifying a bank note processor's handling of circulating bank notes. Independent detectors are provided along the transport path of a bank note processing device. Also provided is at least one independent memory storage device for logging data from the independent detectors. As the note passes along the transport path, the independent detectors evaluate the note's fitness. The independent detector data is subsequently provided to the central bank or commercial organization for auditing of the bank note processor and for generating bank note statistics. Independent detectors may also be used on the transport path output bins to corroborate the other detectors and to verify the integrity of the sorting logic. Mirrored independent detectors allow for corroborating independent data. The invention is operable on any bank note processing device that performs at least a subset of a fitness determination on each note.
