An optional checksum character may be calculated and added to increase scanning accuracy of a barcode.
This property affects Code 39, Code 39 Extended, Interleaved 2 of 5, and Standard 2 of 5. It is ignored in all others.
Note that many symbologies (such as UPC-A) require an already-calculated checksum character.
Do not use OptionalCheckChar property for that purpose - it will be ignored.
BarCodeWiz ActiveX will verify the supplied checksum character, and will notify you if incorrect.
