ABSTRACT:
A method and apparatus for processing documents comprising a unit for reading machine-readable data and for generating image data from the documents as the documents are moved along a track in operative relationship therewith. The unit also includes recognition circuitry receiving the image data and a portion of the machine-readable data to produce recognition data along with confidence level data relative to the recognition data for each document. A control processor is used for storing the machine-readable data, image data, recognition data, and confidence level data by an identification number which is assigned thereto by the control processor for each corresponding document. A second control processor is used for examining the confidence level data for each document to thereby select the machine-readable data, recognition data, and image data for a document having predetermined confidence level data and for transferring the data selected to a terminal to be displayed on an associated display to enable an operator to effect data completion on a keyboard associated with the terminal. After data completion, an encode and sort unit is used to further process the documents.
