I use Zint (http://sourceforge.net/projects/zint/) to generate barcodes.
To read them, there are barcode scanners...

Use zxing library. Can create visual barcode from any kind of string; can decode the content of visual barcode. But, c++ port is a bit undocumented :(

Firstly , you should figure out which app. you want to use: genarate barcode asp.net (http://www.businessrefinery.com/products/barcode_asp_net/main.html) or generate barcode windows forms application project.

Both of them have two ways to generate barcodes,including linear barcodes and 2Dbarcodes.

Then, you can make use of the C# to decode the barcode .

more details you can check the link.

Hope it helps!

Now I am creating barcode in ASP.NET (http://www.onbarcode.com/products/net_barcode_asp_net/) with this tool. It's good. I have been using it for three months. It provides many useful guides of barcode creation, like this tutorial of creating barcode in ASP.NET (http://www.onbarcode.com/tutorial/asp-net-barcode-generation.html), etc.

Not very useful to a Qt C++ programmer who already has a Qt solution though... is it?

The barcode generator allows you to create a barcode graphic by providing barcode data, encoding type, and output file format. A barcode is an optical machine-readable representation of data relating to the object to which it is attached.

I've been using Zxing library to generate barcode and it works fine for me. About the reading part, you will need a barcode reader app to your device(PC, tablet, cellphone) since hardware barcode scanner is little bit pricy. Open sources are not difficult to get on Google.
