[57] ABSTRACT

A currency identification system comprising at least two laterally displaced scanheads, one or more laterally moveable scanheads, or at least two laterally displaced sensors of a linear scanhead. The scanheads or sensors are positioned so as to permit scanning along at least two segments on a first side of a bill. The scanheads or sensors are capable of detecting characteristic information from the bill along the segments and generating corresponding output signals representing variations in the detected characteristic information from which scanned patterns of characteristic information may be generated. The system also comprises a pattern generator for generating at least one scanned pattern from the output signals, the scanned pattern representing analog variations in the characteristic information along a segment of the bill. The system also comprises a memory for storing at least one master pattern associated with each genuine bill which the system is capable of identifying, the master pattern representing analog variations in characteristic information along a segment of an associated genuine bill. The system further comprises a signal processor for performing a pattern comparison wherein at least one of the scanned patterns or portions thereof is compared with at least one of the master patterns or portions thereof. The signal processor generates an indication of the identity of the bill based on the pattern comparison when the bill is one that the system is capable of identifying.
