This is BIG. It means when you leave your house you need to bring:
* Your phone.
That's it.
Your phone is now your money, a dockable laptop, and your keys. This is incredible: like living in a futuristic comic book.
* Your phone.

* Your credit card, for businesses that don't have RFID smart card readers
* Cash, for businesses that don't even take credit cards
* Public transit pass, at least until those start to be supported by phone NFC software, and/or
* Driver's license or ID
Point 3 can be a reality now if you want it (http://www.bunniestudios.com/blog/?p=1379) and will be a reality for most people soon enough.
Point 4 is not actually a necessity (unless you're driving). I've tried to make a point not to carry my driver's license in my wallet (the plastic doesn't own you) except for special occasions. It can be annoying at times, but I've never had a situation where I needed my license for something unplanned (as opposed to forgetting I'd need to prove identity/age at pre-planned activities).
I guess most people can't or won't match my case, but I just wanted to highlight that carrying ID doesn't have to be a necessity.
