OptionalCheckChar

 

 

An optional checksum character may be calculated and added in order to increase scanning accuracy of a bar code. This property affects Code 39, Code 39 Extended, Interleaved 2 of 5, and Standard 2 of 5.

 

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.
