Abstract (en)

[origin: EP0319524A2] An improved currency validator (1) has one or more sensors (18;24;30) positioned along a bill passageway (4) for testing a bill transported along the bill passageway and for generating electrical signals in response to certain features of the bill. Data derived from the electrical signals is processed by a logic circuit, such as microprocessor (102), to determine the authenticity and denomination of the bill, The data may be normalized during its processing. Either or both a histogram technique or a percent denomination space technique may be used in determining the authenticity and denomination of the bill.
