From David Pogue’s Nexus S review
The most exciting hardware news is that the Nexus S can read N.F.C. tags. In case you’re not an engineer, that stands for near-field communications. Supposedly, one day soon, you’ll be able to pass your phone over a special smart tag to pay for something. You’ll be able to wave your phone at someone else’s to exchange e-business cards. You’ll be able to extract information, Web links or videos from special stickers on billboards and bus shelters, just by swiping your phone.
Sure. And then you can hop into your hovercraft and fly home.
Unfortunately, there aren’t any N.F.C. tags in America (except in a Portland test program run by Google), so for now, the feature is worthless. Sure, you could argue that if N.F.C. ever does arrive, the Nexus S will be ready. Unfortunately, by that time, it will look like a kerosene-powered steam pump.
