Do Not Transmit Check Digit After Verification: The scanner checks the integrity of all Code 39
barcodes to verify that the data complies with the check digit algorithm. Barcodes passing the check will
be transmitted except the last digit, whereas those failing it will not be transmitted.
Transmit Check Digit After Verification: The scanner checks the integrity of all Code 39 barcodes to

If the Do Not Transmit Check Digit After Verification option is enabled, Code 39
barcodes with a length that is less than the configured minimum length after having
the check digit excluded will not be decoded. (For example, when the Do Not
Transmit Check Digit After Verification option is enabled and the minimum length is
set to 4, Code 39 barcodes with a total length of 4 characters including the check digit
cannot be read.)
