1D barcode message could contain digits, letters and symbols, etc. 2D barcode message
could contain more data such as Chinese characters and other 2 bytes characters.
Practically, barcode message is insufficient for usage. For example, the barcode format,
the date or a
“
new line character
”
can be useful. Mostly these informations are not
included in a barcode and thus to keep it short and flexible possible.
Prefix/Suffix appended to barcode message fulfills the usage mentioned above. They
can be appended, removed and modified without changing the original barcode message.
