I’m not the only one who feels this way about QR codes. A company called Digimarc recently developed an application that recognizes patterns in images and text using an invisible watermark (only visible through their application but not to the human eye). This way print media can bypass the square QR code. I haven’t tested the app yet but I like the idea of this much better than QR codes too.
There are lots of ways to move people from print or outside media to digital. It’s my view that we can come up with more and better ways to do so with domain names and URLs.
