摘要

A method and apparatus of reading bank notes comprising storing signals in a memory corresponding to at least a portion of an array of pixels defined by a printed pattern on the face of a bank note, raster scanning the face of the bank note with a charge coupled device (CCD) to obtain a serial signal representing the pattern, searching the memory for the serial signal, comparing the serial signal with the stored signals, and indicating the correct presence of the bank note in the event the comparison correlates to a predetermined degree.
