Check Digit Verification

A check digit is optional for Interleaved 2 of 5 and can be added as the last digit. It is a calculated value
used to verify the integrity of the data.
Disable: The scanner transmits Interleaved 2 of 5 barcodes as is.
Do Not Transmit Check Digit After Verification: The scanner checks the integrity of all Interleaved 2 of
5 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 Interleaved 2 of 5
barcodes to verify that the data complies with the check digit algorithm. Barcodes passing the check will
be transmitted, whereas those failing it will not be transmitted.
Since Interleaved 2 of 5 must always have an even number of digits, a zero may need to be added as the
first digit when the check digit is added. The check digit is automatically generated when making
Interleaved 2 of 5 barcodes.
Do Not Transmit Check Digit After Verification
If the Do Not Transmit Check Digit After Verification option is enabled, Interleaved 2 of
5 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, Interleaved 2
of 5 barcodes with a total length of 4 characters including the check digit cannot be read.)
