Can it be done? NFC, which stands for Near Field Communication, lets users hover their mobile phone or other device over a compatible receiver to access content or complete a transaction. It's been used for years with keycard door access and contactless credit card machines.
Where this is making the most headway right now is with mobile payments - in the near future, you'll be able to place your phone over a credit card terminal to pay for a purchase without ever taking out your wallet.
However, a new game called Angry Birds Magic, available from Nokia, takes NFC into the social world. When two users swipe their phones next to each other, they unlock new levels in the game.
We expect NFC to become one of the defining features of the smartphone market later this year and into 2012.
