Method and apparatus for discriminating and counting documents

摘要

A currency identification system for identifying currency bills of different denominations of a plurality of currency systems. The device comprises a discriminating unit for discriminating the identity a bill, the discriminating unit retreiving characteristic information from said 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 at least two currency systems. A signal processing means compares the retrieved characteristic information with master characteristic information associated with at least one genuine bill; the signal processing means generating an indication of the identity of said bill based on said comparison when said bill is one that the system is capable of identifying.
