Submission + - Is NFC Finally Becoming Mobile's Next Big Thing? (wsj.com)

pbahra writes: "It was hard to avoid the message at the recent Mobile World Congress in Barcelona that Near Field Communication was to have its day. If you had the right phone you could bypass the entrance queues with an NFC-powered "badge" on your phone. The halls were strewed with NFC-powered "smart" posters that would unlock all manner of hidden secrets if you tapped them with your smartphone, from restaurant information to directions to the nearest restrooms. There were demonstrations that allowed you to play music on headphones, test if products were genuine or counterfeit, or that let you replace your car keys or your house keys with just your phone.

NFC has been a decade in the making, and has always been about to be "The Next Big Thing". It is a contactless radio technology that can transmit data between two devices within a few centimeters of each other. Coupled with a security chip to encrypt data, it promises to transform a wide range of consumer experiences. The key word there is "promise"."
