NFC's superior physical layer security can be leveraged to securely "pair" Bluetooth and Wi-Fi Direct devices. This is a critical application because once two devices have been paired they will automatically connect whenever they come within range of each other. If the pairing is performed exclusively via Bluetooth or Wi-Fi, then a rogue device impersonating one of the devices could hijack the process. Adding NFC makes "man-in-the-middle" attacks much harder to pull off because the pairing is done in a different part of the radio spectrum using a much shorter range wireless technology.
NFC Is Here To Stay
The evidence that NFC is here to stay is mounting. With the exception of Apple, top manufacturers are integrating NFC with their smartphones. Leading point-of-sale terminal manufacturers are doing the same. And handset manufacturers are offering programmable passive tags that allow individuals and businesses to create their own NFC infrastructure. Samsung's TecTiles and Sony's SmartTags can be programmed to initiate tasks such as changing the phone's settings, placing a call, or pulling up a web page. The uses for programmable NFC tags are limited only by the imagination. Tags affixed to automobile dashboards can be used to turn Bluetooth on or off with just a tap. Tags installed on retail displays can direct shoppers' phones to web pages with additional product information.
The biggest threat to NFC-based payments is an alternative solution that catches on first. So far, no other solution has proved to be as convenient and reliable as NFC. There are apps that encode payment details as bar codes (or QR codes) displayed on phones' screen, but laser scanners sometimes have trouble reading them. Other solutions avoid sending payment details over the local link but are vulnerable to identity theft.
NFC's tap-and-go operation will appeal to consumers. Tap-and-go is a constant reminder that NFC works only at close range. Much like turning on a light switch, tap-and-go is deliberate and tactile--it gives users the sense that they determine when NFC is used. Consumers will need time to get used to tap-and-go operation, but once they do they will find it even easier and more natural than swiping a credit card through a card reader. (continued...)

There is also a technology on the market now that is used for mobile authentication and is compatible with IOS, which is something that NFC is severely lacking right now. It also can be done for a fraction of the cost. Check out www.snowshoestamp.com for more information.
