Check Digit Tab
This tab is used to specify if you want to use the check digit in the bar code or not. This option can
only be modified for the bar codes that allow you to enable and disable the check digit.
Some bar code standards include the check-digit by the definition and it cannot be omitted. An exam-
ple of such bar codes are EAN and UPC bar codes, where check digit cannot be disabled at all. But
some codes allow you to freely enable/disable check-digit.
Note:
It is always recommended to include the check digit character in the bar code. It will increase the
scanning reliability.
