C - 6
The check digit is verified but filtered from the reading result when the option
"Verify and Erase Check Digit" is enabled, otherwise, it is read and included in
the output. Disable this option to support the variation of UPC which does not
contain a check digit.
Apart from the check digit, there is a left, center and right guard pattern. The
first half of the bar codes uses odd parity digits, the second half uses even parity
digits.
UPC stands for “Universal Product Code” - has been designed to uniquely
identify a product and its manufacturer.
A version of UPC, UPC-E, is restricted to 6 digits and “zero suppressed” -
UPC-E compresses the 12 digit UPC codes into six digits by suppressing the
number system digit, trailing zeros in the manufacturer's code and leading zeros
in the product code. The IRISPen Executive does not support this variation.
