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.

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

Prefix/Suffix appended to barcode message fulfills the usage mentioned above. They

can be appended, removed and modified without changing the original barcode message.

1. Intersect barcode message

2. Append Prefix/Suffix

3. Pack

4. Terminate with Stop Suffix and transmit
