Well, I'd say it's because of legal issues. A couple of months ago I was investigating QR codes. Other than the fact most (if not up to 80%) of people either don't know what a QR code is or how to 'read' it. It's a pretty clever design, at its core is encoding binary data to an image (largest is about 512KB if I remember correctly). Liability comes into play when you consider that it's possible to encode a virus or other malicious code into QR readable format which people can willy-nilly scan into their phones.
