Looks like a great way to expand the use and popularity of NFC. I'm looking forward to a much more universal adoption of the technology. It seems like every store has their own "membership" card to get special pricing, etc., so not having to carry all of those as well as credit cards, etc. would really be a boon.
Have you been in Japan, there mobile payment is on, and working for long. Anything you can pay, book with your mobile. No need to carry plastic cards or $$s. Just your phone. i say it would change a lot, just not in a way as reveal of first mobile phone. :)
We can see the business and market brewing for the very near future. Apple is getting in to this, Broadcom, Qualcomm, NXP.
Systems already being deployed. It's a fact... NFC is coming... our lives will never be the same... (did I sound dramatic? :)).
All you engineers out there ... better start studying this new technology!
