Check reader utilizing sync-tags to match the images at the front and rear faces of a check

摘要

An electronic document-imaging arrangement wherein imaging means generates imaging-bits representing a given document and transfers these bits on a "per-document basis" to various successive electronic processing stages and, finally, to a data base storage unit (DBS); this arrangement also including a tag stage for creating tag bits unique for each such imaged document; these tag bits to be transferred with the imaging bits for each document to each such processing stage that handles the imaging bits, on a per document basis, and finally to DBS interface means for final matching and removal of the tag bits.
