Near Field Communication (NFC) lets users wirelessly transfer data over short ranges. All you have to do is tap an NFC device against another and the data starts to transfer. At Google I/O 2011 we found that this will be a feature in Ice Cream Sandwich and that it will be used a bit more extensively than the previous Google Wallet.
Google says that you will be able to now transfer information between 2 NFC devices by simply tapping. There will be no need to open an app first, you just tap and done. In their demo’s they have shown us that you can transfer contacts, websites, apps, and youtube videos by tapping. Other items that have been mentioned are calendars, music, files, etc.
“We want to build this into as many system apps as we can.”
“Here’s some ideas we’re going to put in the Ice Cream Sandwich Release.”
You will of course need NFC on your device although most new phones will have this capability. We also can only assume since the NFC features will be built into Ice Cream Sandwich that any phone coming with it starting in October of this year will also have NFC.
