Abstract:
A method and apparatus for evaluating a confidence level of a decoded barcode value is disclosed. A digit score is assigned to a digit within a barcode. When decoding the barcode, if a deduction is required to decode the digit, then the digit score for the digit is reduced accordingly. After all the digits within the barcode have been decoded, a total score of a decoded barcode value can be determined by adding all the digit scores for all the digits within the barcode. The total score of the decoded barcode value is reduced if a checksum is used to ascertain the value of any digit within the barcode. The decoded barcode value can be accepted only if the total score exceeds a predetermined value.
