What exactly are NFC tags and how do people use them in everyday life?

Tom Six April 9, 2013

I just got the Samsung GS3 and I love it. In my eyes, this phone is amazing.

Lately I’ve been hearing stuff about NFC tags, but am not really sure what they are or how they can really benefit me, a day to day person. And so I would like to know what are NFC tags and how can they help every day people, like me? How do others use them?

    You can use NFC Task Launcher (https://play.google.com/store/apps/details?id=com.jwsoft.nfcactionlauncher) to program your tags. And here's a list of cool use cases:

    You can use a NFC to unlock your front door. Just get close to the sensor and the door unlocks. No need for a key.

    An example would be the movie "Over the Hedge". the cat's collar is is NFC. he gets close to the cat door and it unlocks to let him in or out. The forest animals had to get the collar to get inside the house to steal the food.

    Also, you can set up a tag in different places to change settings on your phone. Sit at work and a tag under your desk sets you phone to set volume to vibrate only. Get home and the volume is set to loud. Going to bed? the tag there sets the silent.no vibrate mode.

    Its pretty wild what they can do. One that I would never use is the one for credit cards. Get it close to a reader and it will be read. I don't like that idea. though, there are wallets that are being made now to protect them from being read unwittingly.

    NFC in General:
    NFC allows a smartphone to interact with the world around you. It allows you to store information or instructions on the tag so that the phone reacts in a specific way when it touches it.

    NFC is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters.

    in basic words : it is transferring data just by tagging a phone to another

    it is used for gaming , transfer of data , etc.
