Check Digit
The check digit control can be enabled to improve decoding safety: it is generally the last digit aligned to the right of
the code and verifies the validity of the preceding digits. The calculation technique and number of check digits depend
on the code selected.
It is advised to enable the check digit whenever correct code identification is difficult.
The following barcode symbologies include check digits in their definitions:
- Code 128
- EAN/UPC

For these symbologies the check digit control is not allowed.
