Near Field Communication, short for NFC, have been mentioned a number of times on the internet. Topic about NFC technology is really stirring and wonderful because of the endless possibilities it affords us. Today, hot NFC is finding its way into more and more device and isn't only for phones now. There are devices called NFC tags, and they can really shake up the way we do things.

NFC let two devices to send data to each other simply by touching or bringing them into close proximity, usually no more than a few centimeters. First, in order to get a distinct understanding about NFC, Let’s go together to have a review the advertisement of Samsung phone, which demonstrate the details of data transfer for us in real life.

What Are NFC Tags
However, there are little units called NFC Tags now, which are becoming increasingly more popular. NFC Tags, for example stickers or wristbands, contain small microchips with little aerials which can store a small amount of information for transfer to another NFC device, like perform a number of actions, like open a map, launch a website, change your phone's settings and configurations or even setting an alarm, plus dozens of other tasks via NFC.

Uses
Nowadays, we are likely see commercial ads and posters with QR Codes on them everywhere we go. You can also download android app by Scanning QR-codes. See, QR Codes can be useful but are a bit clumsy. First, you need a barcode scanning app on your device; second, you need to be in the right light, and you need to capture the QR Code properly. But with NFC tags, you can get information off an ad just by holding your phone to it. Samsung allows you sending the free music and videos with its Galaxy S III, via the amazing and powerful NFC tags.

Image stores equipping everything they sell with NFC tags so that you can purchase an item from your phone and walk out of the store with it.

How do I Use Them?
You can currently purchase your own NFC tags from famous online companies such as TagsForDroid.com and others. In addition, The Sony Xperia Smart Tags are available for purchase, and Samsung has its own called TecTiles.

  2. Configure the tag’s action on the app
  3. Hold the tag to the phone so it gets programed
  4. Start using the tag.
