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.
Step 1: What You'll Need
You will need:
- An phone with NFC functionality
- The NFC Task Launcher app for Android ($1.99)
- Some NFC tags- I got mine from TagStand*
- A little creativity
*There are a few different type of NFC tags. To be on the safe side get NDEF preformatted tags, unless you know your phone works with unformatted tags. Also, type 2 tags will work with future iterations of NFC, so consider those. Finally, check the capacity of the tags. Simple tasks require little memory, but swtich tags with multiple tasks can require a more than the 48 bytes available on some tags.
