NFC. It stands from Near Field Communication. And it's invading the world, one small step at a time.
Perhaps its biggest jump into the mainstream is thanks to the new Nexus S from Google. It runs the new Android 2.3 (Gingerbread) software update, which takes full advantage of the NFC chip inside the smartphone.
If your Android device doesn't have the chip yet… it's only a matter of time. The Nexus S is so future-proof that it has an NFC chip for reading smart tags! Google Nexus shows you all about it in this video.
