NFC stands for "Near Field Communication” and the Nokia C7 is one of the first devices to support it.
So why should you care? Well, Rovio, the developers of Angry Birds, are
betting that Angry Birds will be even more fun when played with friends.
"Angry Birds Free with Magic” will come preloaded on the Nokia C7 as
part of the Symbian Anna update and will contain twenty new levels, but
only five will be unlocked to start.
This is where things get interesting. To unlock the other levels you
have to find someone else with an NFC enabled phone–then, as shown in
the video below–you swipe your phones and "magically” five new levels
will be unlocked. So, in other words, to unlock all fifteen levels
you’ll need to find three poople with NFC enabled devices.
