Though it's increasingly less certain that near field communication will appear in the iPhone 5, it's a technology that's built into a lot of high-profile products already. So, what is it exactly? And how relevant is it today?
What is NFC? NFC is a short-range wireless connectivity technology that uses magnetic-field induction to enable communication between electronic devices in close proximity. (Faraday's law: any change in the magnetic environment of a coil of wire will cause a voltage to be induced in the coil.)
NFC can operate in three modes, according to an NFC whitepaper:
- Smart tag: In this case, the user touches, for example, a mobile phone against an NFC tag, which provides a small amount of information to the device. This could be used for getting information about a product in store or for downloading information about medication.
