I think this is what the module is intended for. The admin page is just for creating codes manually. To create codes dynamically, e.g. for a recipe module, you need to add one of the code snippets from the help pages to the PHP that drives the module template and feed in a variable, such as the Xoops URL for that recipe. The script then calls the QR code module and the QR code is displayed.
If the QR code contains just a URL, most code readers in phones will automatically load the web page in the phone browser. Of course, this will be the same web page they are viewing on their desktop PC. The Webphoto solution modifies the URL slightly to take the user to a simple page optimised for mobile browsers.
