If you’re wondering what the buzz about Near Field Communications (NFC) might be, you’ll want to read The Register‘s Beginner’s guide to NFC:
Near-field communications (NFC) will take off very quickly — once it’s clear who can make money from it.
From the look of it, 2011 is the year that it will all become clear.
Mobile handset vendors are rushing to incorporate NFC into their roadmaps, with several high profile NFC-enabled handset launches pencilled to lauch mid-2011.
RIM recently hinted at incorporating the technology into new BlackBerry devices, the iPhone 5 is widely expected to include an NFC chip, and Samsung and Nokia are understood to be planning several NFC-enabled phones.
Mobile operators are gearing up too. In the UK, for instance, O2 is building out an NFC team and forecasts that near field communications will enter the consumer mainstream in mid-2011. Orange UK is equally bullish, forecasting sales of 500,000 NFC-enabled phones this year.
So what’s the fuss all about?
If they’re right, expect to start seeing this symbol on lots of things in the near future:
The N-Mark standard defines an embedded tag, which can communicate and provide encrypted authentication using power induced by the reader – such a tag can therefore be embedded in a credit card or key fob without needing its own power supply.
An N-Mark device, such as a mobile phone, incorporates a reader as well as a tag, to enabling communication with passive tags and other N-Mark devices. That communication takes place at 13.56MHz, but as the power is magnetically inducted the range is extremely limited – 200mm at best.
