Abstract: For use with a physical document bearing content visible when illuminated by light in the human visible spectrum, a tag printer, a verifier and a document processing system employing one or both of the printer and the verifier. In one embodiment, the tag printer includes: (1) a processor operable to generate metadata regarding the physical document and (2) a printer associated with the processor and operable to print a tag containing the metadata on a location of the physical document irrespective of locations of the content using an ink substantially invisible in the spectrum.

Abstract: A document processing system including a modular transport system which includes a digital image capture system, character recognition circuitry, document encoding systems, endorsers, audit trail printers and an in-line microfilm record system. Associated video terminals and non-impact printers are utilized to provide visual images of documents processed by the system. Selected documents may be read, endorsed, encoded, digitally imaged, filmed and sorted in a single continuous pass through the document processing system of the present invention.

Abstract: A mechanism for encoding continuously moving documents. Documents are transported between a plurality of fixed dies and a plurality of electronically controlled hammers. An ink bearing ribbon is interposed between the documents and the fixed dies and is momentarily transported at the same velocity as the documents. As the documents traverse the plurality of fixed dies, the electronically controlled hammers are cycled, in a selected sequence and at selected positions, to provide the desired encoding. In those applications wherein the cycle time of the electronically controlled hammers is too slow to allow identical encoding in adjacent positions, a second plurality of fixed dies and electronically controlled hammers may be located adjacent to the first plurality or interspersed among the first plurality of fixed dies.
