According to one leading analyst, Apple's much-rumoured iPhone 5 and iPad 2 devices are to get NFC technology. What does that mean? Read on to find out.First off though, the source of the rumour. That's from Richard Doherty of Envisioneering Group and according to Engadget, he has claimed that 'engineers who are working on hardware' for Apple have said that NFC capabilities are being built into the next iPhone and iPad devices.So why should you care? Well, the technology is slowly taking hold, with Japan very keen on the idea and the rest of us slowly coming round to it. Oyster Cards for travel in London are one example of this 'contactless' technology in action, while McDonalds has introduced similar, credit card-based technology for its restaurants in the UK. If Apple joined the game, that could really change things, especially in terms of marketing it.According to Doherty, the idea would be to allow the use of iTunes gift card balances and the credit card info Apple already has from you to make swiping payments at compatible retail outlets. Still not sold on the idea? Apple is also considering throwing in enticements, like loyalty credits and points, to get you using its service instead of the competition.Security could be an issue, especially if you're prone to leave your phone lying around (or you have a track record of losing your handset). But as long as there are safeguards, the novelty alone could see this really take off. With the iPad 2 just around the corner (allegedly), look out for more on this in a matter of days.
