There are quite a few free online QR code generators. Take a look at qurify. They'll do something like this:

There's no central authority for QR codes or anything; it's just a bar code encoding of text. Devices are often able to "sense" that a URL is encoded in the QR code and automatically go to the link, but they're just reading the code and deciphering the text.

Google has a QR code API service that is free, but this is due to be phased out in 2015.
Code:
https://chart.googleapis.com/chart?&choe=UTF-8&chs=150x150&cht=qr&chl=http://mywebsite.com/
chart


There are also a couple of free PHP scripts out there on the web to create QR codes and a quick search should find them.

My favourite is qrjumps.com , which also allows for a variety of features like passwording QR Codes.
