Chapter 7 Prefix & Suffix
Introduction
A 1D barcode could contain digits, letters, symbols, etc. A 2D barcode could contain more data, such as
Chinese characters and other multi-byte characters. However, in real applications, they do not and should
not have all information we need, such as barcode type, data acquisition time and delimiter, in order to
keep the barcodes short and flexible.
Preffix and suffix are how to fulfill the needs mentioned above. They can be added, removed and modified
while the original barcode data remains intact.
