Are Qr Codes catching on in the UK and US? I live in Japan and they are everywhere. It's hard to imagine things not using QR Codes here. A while back I was really surprised to see the States not implementing them. I'm not sure why that is. If you ever go to Japan you'll see those little QR codes on just about everything in print. It's amazing. In any event, I think QR Codes are awesome and very convenient. Hopefully they'll catch on more and become more mainstream.
