Checksum Verification - Inateck P6 User Manual

3.11.2. Checksum Verification

Checksum character is not enforced to be included in the IATA 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", which is default, then the scanner will read
and output all the barcode data.
If the scanner is set to "Verify with Output Checksum Character", and the scanner will
check the data based on the last character of the barcode data. If the check passes,
Inateck P6 will read and output the Checksum Character as the last character of normal
data; However, it will not be able to read IATA 25 without checksum character.
If the scanner is set to "Verify without Output Checksum Character", and the scanner
will check the data based on the last character of the barcode data. If the check passes,
Inateck P6 will read but will NOT output the Checksum Character as the last character of
normal data; However it will not be able to read IATA 25 without checksum character.
