More and more smart phones are coming out with NFC capability.
But what does that mean for you? A few things: the ability to send data over a very small distance to another phone, the ability to use your phone as a wallet, and the ability to read and write NFC 'tags'.
NFC stands for 'Near Field Communication
' and is more or less an RFID (think of the anti-theft tags on clothing) that can engage in two way communication. Some neat things about NFC is that the tags are unpowered and don't have to make contact with the reader to work (though they must be very close).
This instructable will show some ways I've made my mobile life simpler by using NFC tags to automate some functions on my phone. My hope is that you will find them useful or that you will come up with your own ideas. Cool factor aside NFC tags can be very useful and practical.
Sorry apple fanboys, the NFC party is Android only for now. I'd bet money you'll see it in the iPhone 5 though.
