Choosing a Bar Code

How do you choose a bar code? It can be quite confusing. Some industries use a standard bar code type. If that’s the case for you, all you need to do is buy the proper bar code set.

The choice of a bar code can also be determined by what kind of data you want to encode. Some bar code symbologies only encode numbers (bar code 2/5 interleaved, EAN, PostNet, and UPC) while other bar codes only encode a fixed number of digits (EAN 8, EAN 13, and UPC-A). There are also some bar code types let you encode both numbers and upper case letters (bar code 3 of 9 and bar code 93) or even the complete ASCII character set (bar code 128). Read more…
