One day, we’ll all be paying for things with our phones, and NFC is the ticket to that future.
From the linked article:
"NFC (Near-Field Communication) allows two devices placed within a few centimeters of eachother to exchange data. In order for this to work, both devices must be equipped with an NFC chip."
Like those kewl commercials where people share photos just by holding their phones close to eachother. Or, for iPhone, the AirDrop™ feature.
