NFC, the brainchild of Sony and NXP, is at the bottom of the wireless totem pole. It allows two devices embedded with chips to snuggle up together and transmit small pieces of data between each other when they are in close proximity. This data can be credit card information, coupons, tickets...you get the idea. As all of this is rather sensitive, it means you'll need to get up close and personal with the other device in order for it to suck down your data -- a simple swipe or tap should do the trick, and your most intimate bytes will soon be whisked away into the wilds of the internet.
Editor's Note: Unless your "intimate data" is encrypted, an innovate new "NFC security platform" created by the folks at NFC Data. Their NFC Card Reader, (pictured below) is also an NFC reader/writer and viewer, is tamper proof and can store unlimited credit, debit, membership, rewards and loyalty cards. Sqwizz features a built-in biometric finger scanner AND a 3DES DUKPT encrypted PIN Pad which is hard wired to the CPU. Why? Because it ensures a secure NFC experience. After all, you don't want your "most intimate data" whisked away into the "wilds of the internet" You'll want it secured and protected. Which is exactly what Sqwizz does. Whomever said "convenience and security" were mutually exclusive hasn't had a Sqwizz in their hands... (want more info?)
