Introduction

In many applications, barcode data needs to be edited and distinguished from one another.
Usually AIM ID and Code ID can be used as identifiers, but in some special cases customized prefix and
terminating character suffix like Carriage Return (CR) or Line Feed (LF) can also be the alternatives.
Data formatting often refers to appending prefix/suffix to original data, data packing, etc.
Data formatting procedure:
Append AIM ID/Code ID/custom prefix before the decoded data
Append custom suffix after the decoded data
Pack data
Append terminating character to the end of the data
