3.13.2 Checksum Verification

Checksum character is not enforced to be included in the Matrix 25 data. If checksum character is
included, it should be the last character of the barcode data. As a calculate value bases on all the
data, Checksum character is used to check if the data is correct or not.
Thus, if the scanner is set to "Do Not Verify Matrix 25", which is default, then the scanner will
read and output all the Matrix 25 barcode data.
If the scanner is set to "Verify Matrix 25 with Output Checksum Character", and the scanner will
check the data based on the last characters of the barcode data. If the check passes, the scanner
will read and output the Checksum Character as the last character of normal data. However, it
will not be able to read Matrix 25 without checksum character under this setting.
If the scanner is set to "Verify Matrix 25 without Output Checksum Character", the scanner will
check the data based on the last characters of the barcode data but will not transmit the
checksum character. However, the scanner will be unable to read Matrix 25 barcode without
Checksum character under this setting.
