3.4.3. Checksum Verification

Checksum character is not enforced to be included in the data of Code 39. If checksum
character is included, it should be the last character of the barcode data. As a calculate
value based on all of the data, Checksum character is used to check whether the data is
correct or not.

the barcode data.

check the data based on the last character of the barcode data. If the check passes, It will
