This parameter sets the OCR module check digit calculation.
The check digit is the last digit (in the right-most position) in an OCR string and improves the accuracy of the collected data. The calculation is performed on incoming data to determine this check digit, based on the numeric weight of the alpha and numeric characters. See OCR Check Digit Multiplier. If the incoming data does not match the check digit, the data is considered corrupt.
To choose the Check Digit Modulus, such as 10 for Modulus 10, scan OCR Check Digit, and then scan a three-digit number from 001 to 099 representing the check digit using the numeric keypad in Numeric Barcodes.
