Check Character Verification
A check character is optional for Matrix 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 transmitsMatrix 2 of 5 barcodes as is.

Do Not Transmit Check Character After Verification: The scanner checks the integrity of all Matrix 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 Matrix 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 Matrix 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 Matrix 2 of 5 barcodes.

Transmit Check Character After Verification
If the Do Not Transmit Check Character After Verification option is enabled, Matrix 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, Matrix 2 of 5 barcodes with a total length of 4
characters including the check character cannot be read.)
