Abstract: Disclosed is a system for processing documents in a two pass arrangement. During the first pass, an image is stored along with a digital image signature relating to a portion of said image. On the second pass the image signature is compared with stored image signatures seeking a unique match. If that unique match is found, the associated record stored is used for controlling the function of the document processing system, for example, printing an amount field or sorting the document into a selected sorter pocket.
