BarCodeWiz Logo


An optional checksum character may be calculated and added to increase scanning accuracy of a barcode. This property affects Code 39Code 39 ExtendedInterleaved 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.
