Check Character Verification
A check character is optional for Interleaved 2 of 5 and can be added as the last character. 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 Character After Verification: The scanner checks the integrity of all Interleaved 2 of 5
barcodes to verify that the data complies with the check character algorithm. Barcodes passing the check will be
transmitted except the last digit, whereas those failing it will not be transmitted.

Transmit Check Character After Verification: The scanner checks the integrity of all Interleaved 2 of 5 barcodes to
verify that the data complies with the check character 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 character is added. The check character is automatically generated when making Interleaved 2 of 5 barcodes.

Transmit Check Character After Verification
If the Do Not Transmit Check Character 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 character
excluded will not be decoded. (For example, when the Do Not Transmit Check Character 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 character cannot be read.)
