Explaining it a bit better, you'll need a web-enabled phone. That's becoming much more common these days. There will be even more soon, as the cell providers are upgrading their networks and offering web access at lower rates. Once you have the software on the phone, you can shoot a picture of these qr codes wherever you see them. They are appearing in print ads, on brochures and many other places. When you scan one, you are taken to the web page the marketer wants you to see. Of course, it will be optimized for viewing on a cell phone.
