Verification of Optional “Check Digit”
Code39 and Interleave 2 of 5 have an optional check digit, which, by default, is not verified.
Changing the option VerifyCheckDigit to true may enable their verification, or the user may
enable the verification for individual symbologies. If the check digit verification fails, the
barcode is not transmitted.
Transmission of “Check Digit”
By default, the check digit – optional or mandatory – is not transmitted. Its transmission may be
enabled for all symbologies by enabling ReturnCheckDigit option.
