There are many different barcode schemas.
The most easiest one is Code39
Almost all of them are pretty much a special font. Meaning that A is 2 fat
lines and 3 narrow lines, B is 1 fat line, 2 narrow and then 1 fat.......
(it's just a sample).
So to insert barcode into anything you simply need to output text with
special font. You can download code39 font for free from internet. The
differences between schemas is in how they have error corrections.
For example code39 is prefixed and suffixed with symbol '*'
So Order number 345 in code#9 notation will be *39*. Then Barcode reader
will automatically recognize it and enter into computer as if you punched
keys 3 and 9 on a keyboard and hit enter (that behavior is configurable in a
reader)
To Read barcode you need a scanner similar to those you can see in a store.
