Abstract

A currency identification system identifies currency bills of different denominations of a plurality of currency systems. The device includes a discriminating unit for discriminating the identity of a bill, the discriminating unit retrieving characteristic information from the bill. Furthermore, a memory stores master characteristic information associated with each genuine bill which the system is capable of identifying; the memory storing master characteristic information associated with at least one genuine bill from each of at least two currency systems. A signal processor compares the retrieved characteristic information with master characteristic information associated with at least one genuine bill. The signal processor generates an indication of the identity of said bill based on the comparison when the bill is one that the system is capable of identifying.
