Huh .. I had an idea like this a few weeks ago when I saw a video about paying with your phone using NFC. However, I usually think my ideas to death, so I ended up dismissing it. Probably why I'm not an entrepreneur. My problem was perhaps that I considered it in the scale of small coffee shops, and found the hassle of them getting the infrastructure and the increased overhead of printing and scanning codes to be too big of a problem for adoption. However, for larger chains, this seems like an excellent solution. Getting the infrastructure in place won't be such a big problem if you roll this out across, let's say McDonalds. You could have a McDonald's-specific app and tie it in with Facebook and Twitter and Gowalla whatnot. But for smaller shops, there might not be such a big advantage. They might not even need this. But I'll happily be proven wrong.
