If QR codes were automatically detected with the iPhone camera app, they would boom.

95 percent of the problem is non-tech people don't know they need an app to scan or can't be bothered with getting one.

I've literally seen a friend of mine try to take a photo of a QR code and complain it doesn't work.

It's like having a PC without a web browser -- what the hell do you do with a URL then?
