One-tap hookup
Another convenience newer forms of Bluetooth brings is compatibility with NFC chips. Both Bluetooth versions 3.0 and 4.0 can talk to NFC hardware in phones and laptops to make pairing a simple process of tapping the two devices together. So you can imagine configuring Wi-Fi settings on mobile gadgets just by resting them on NFC equipped routers or hooking up headsets with
tablets and phones in the same manner. For example, Motorola's new
Elite Sliver headset already has this NFC pairing ability. Frankly the idea setting up a gadget this fast gives me goosebumps.
*****************
As Gil notes, that’s a huge lost sales opportunity that could be addressed with using Bluetooth Low Energy, because it would increase global demand from retailers looking to replace their registers with Bluetooth 4.0 equipped Macs, iPads, iPod Touches and iPhones.
The genius of this plan? It’s already deployed. There’s no need to find room in every iPhone for an extra chip, or wait for other companies to get their act together about NFC and actually get it into stores. Because Apple has been deploying Bluetooth 4.0 equipped devices since mid-2011, all Apple really needs to do to suddenly become a mobile payment company is go on stage at WWDC next month, officially announced iOS 6 and then say:”BAM! iWallet! It’s here… and your iPhone 4S is
already capable of it!”
Makes sense to us. Look at what Google’s going through with Google Wallet, a thoroughly stalled NFC initiative for Android. People have been talking about NFC for years, and yet it’s still not even close to taking off. If Apple’s really going to enter mobile payments, doesn’t using a technology that embraces Apple’s own retail philosophy, helps sell more Macs and uses technology you already have in your pocket make a lot more sense?
