On-line correction of check code line recognition in point-of-sale stations
First Claim
1. A method of identifying a certificate at a point-of-sale terminal, said certificate having a code line of characters, said characters being represented by at least human-readable indicia, comprising the steps of:
- conducting a first type of automatic character recognition on at least a first portion of said indicia at said point-of-sale terminal;
conducting a second type of automatic character recognition on at least a second portion of said indicia at said point-of-sale terminal;
responsively to said steps of conducting a first type of automatic character recognition and conducting a second type of automatic character recognition identifying at least one unrecognized character of said code line;
generating an image of at least one of said human readable indicia that corresponds to said unrecognized character at said point-of-sale terminal;
communicating said image to a remote human evaluator for identification of said unrecognized character by said human evaluator to define an identified character;
returning said identified character to said point-of-sale terminal;
replacing said unrecognized character with said identified character to form an identified code line; and
communicating said identified code line to a payment system.

Abstract
Methods and systems are provided for check code line recognition at a point-of-sale terminal having OCR and MICR capabilities. Images of problematic characters are extracted and automatically transmitted to a remote location for on-line manual validation or data entry. Video coding of problematic characters is performed for the correction of either or both MICR and OCR results. The correctly encoded characters are returned to the point of sale within a few seconds, and combined as necessary with locally recognized characters, to assemble a correct code line for entry into a payment system.

7. A computer software product, including a computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to perform a method for identifying a certificate at a point-of-sale terminal, said certificate having a code line of characters, said characters being represented by indicia, at least a portion of said indicia being human-readable, comprising the steps of:
-
conducting a first type of automatic character recognition on at least a first portion of said indicia at said point-of-sale terminal;
conducting a second type of automatic character recognition on at least a second portion of said indicia at said point-of-sale terminal;
responsively to said steps of conducting a first type of automatic character recognition and conducting a second type of automatic character recognition identifying at least one unrecognized character of said code line;
generating an image of at least one of said human readable indicia that corresponds to said unrecognized character at said point-of-sale terminal;
communicating said image to a remote human evaluator for identification of said unrecognized character by said human evaluator to define an identified character;
returning said identified character to said point-of-sale terminal;
replacing said unrecognized character with said identified character to form an identified code line; and
communicating said identified code line to a payment system. - View Dependent Claims (8, 9, 10, 11)

12. A point-of-sale terminal of identifying a certificate, said certificate having a code line of characters, said characters being represented being represented by indicia, at least a portion of said indicia being human-readable, comprising:
-
a first reader for conducting a first type of automatic character recognition on said indicia;
a second reader for conducting a second type of automatic character recognition on said indicia;
an arbitration module operative in real-time responsively to said first reader and said second reader for identifying at least one unrecognized character of said code line;
an imager for producing an image of at least one of said indicia that corresponds to said unrecognized character; and
a communication facility linked to a remote human evaluator for identification of said unrecognized character by said human evaluator on said image to define an identified character;
wherein said point-of-sale terminal is operative to accept said identified character, to replace said unrecognized character with said identified character to form an identified code line, and to communicate said identified code line to a payment system via said communication facility. - View Dependent Claims (13, 14, 15, 16, 17, 18)
