1. Make sure that NFC is turned on in Settings > More > NFC and make sure that Android Beam is also on in the same section.
2. Hold the two devices back to back (they have to be almost touching) and you'll feel a vibration.
3. After it vibrates you'll see the content on your device turn into a card-like object with Star Trek warp speed-looking animation in the background.
4. Tap the card and the content will then load on the other person’s device.
