Still not a wallet, NFC has a second life as a safe, simple pairing tool

NFC, or Near Field Communication, radios may be better device pairing tools than they are digital wallets. At least, that’s how it appears based on how people are using it. The technology gained some awareness as the wireless radio behind Google Wallet in 2011 but is seeing more success in the market as a simple way to wirelessly connect two devices.

I was reminded of that by Samsung’s newest product announced on Thursday.

The company claims to have the first NFC-enabled color laser printer and multi-function printers. Instead of needing a direct wired connection to the printers or looking for them on a network, you can simply place your NFC-enabled smartphone or tablet on the printer to pair the two. Print data is then sent wirelessly through Wi-Fi Direct. You can even scan a document and send it electronically back to a smartphone using this method.

This is just the most recent example of NFC and simple device pairing. And it is simple; much more so than getting two Bluetooth devices to talk to each other. The difference is one of physicality.

Bluetooth radios have a range of 10 meters or more so anyone in that radius could theoretically attempt to pair their device with one of yours over Bluetooth. That’s why when you pair Bluetooth devices, you’re provided with a simple PIN to authenticate the connection. But the “N” in NFC stands for near and that makes all the difference: Why require a PIN when two devices are placed within an inch or two of each other?

I’ve noticed many more wireless accessories using NFC as the pairing method, and nearly all of them use Bluetooth technology for data transmission. Essentially, NFC is replacing the Bluetooth connection method in these devices which still use traditional radio technologies — both Bluetooth and Wi-Fi — to transmit music, video, pictures or other data.

Need more examples? The SOL Republic Deck speaker for Motorola’s(s goog) Moto X (see our phone review here) is one.

Sony’s(s sne) SBH20 Stereo Bluetooth Headset is another that uses NFC to pair the headphones to a handset. In fact, Sony is adding NFC to some of its HDTV sets to allow simple pairing between a mobile device and the TV in order to facilitate wireless media streams from the small screen to the big one. And Hyundai is looking at using your NFC-enabled smartphone as the keys to your car.

NFC could still find a home as the basis for a digital wallet. For now though, investments in NFC as a simple pairing tool are starting to pay off and the radios will likely start filtering down into mobile devices at every price range.
