Nokia Lumia 925 - What does the Tap to share (NFC) mean in the share menu of the Cinemagraph app on Lumia phone?

By using Tap to share (NFC) you can copy Cinemagraph animations straight to your friends who have Cinemagraph installed on their Lumia phone. It uses NFC technology to connect and copy the animation to the second phone so that it can be viewed and edited directly in the Cinemagraph application there.
