Parrot has come up with a new Black Edition of their PARTY speaker which uses Near Field Communications to connect to audio sources, claiming it's the first commercial speaker system to do this. Basically you don't have to do any complicated Bluetooth paring, just tap your cellphone to the speaker and away you go. It uses a class-D amp, has a 6W power output, a "Stereo Widening" option to create virtual surround sound and its rechargeable batteries will last eight hours. Available in the summer in the UK for around $156. Update: Ok, we thought they did, then we thought they didn't: Parrot contacted us, very sweetly, to say "yes... they are NFC enabled." Hooray. Sorry for the confusion. [Pocket Lint]
This is just using the NFC 'Out of band' option for Bluetooth 2.1's 'simple pairing'. It's a nice way to do things, however as far as I know only Nokia have implemented NFC in a phone to-date, and that may have been for micro-payments rather than for Simple Pairing.
i.e. It may be a while until this method becomes common practice (if ever). However I'd love to see it happen.
