1. Serving Up a Non-Mobile Page

QR codes are meant to be used exclusively by Mobile users -- scan the Code on the go with your smartphone and view whatever it's linking to on the very same phone, right? I think we can all agree on this. Given that, it boggles my mind when I find a QR code that directs the end user to a "regular" (non mobile) website. Sure, most of these websites can be viewed on an iPhone or Android, but why wouldn't you take that extra step and make everything easier and more streamlined?
