Just for comparison, I had phones (flip-phones, mind you) from Samsung, LG, and Motorola with NFC in 2006. We could use them at MCD's, 7-eleven, and a few other places. Fast-forward 9 years and there has been little uptake, except that there are phones actually available to people with NFC, and acceptance is more commonplace.

In general, people take much longer to adopt new technology than we would like to see.
