Abstract: The processing of documents evidencing business transactions is enhanced by optically scanning and imaging only specific areas of interest, amount fields for example, and simultaneously storing the imaged amount fields in two separate files. Subsequently, only those images which correspond to a dollar amount which has not been successfully read will initially be displayed to an operator for key entry of the amount. A balancing procedure is performed and if a comparison of the total of the individual imaged amounts equals the total entered on a summary document further key entry of amounts will be unnecessary.
