NFC is here!!
Obviously enough, Near Field Communication or NFC to save us some time is communication between two devices over a short distance. Usually around a few centimeters, sometimes these devices require the two devices to be in contact with each other for them to communicate. NFC works on the principle of Induction Coupling. In short, Induction Coupling means that and current flowing in a circuit produces a magnetic field and this magnetic field is capable of producing a current in another circuit.
NFCs find themselves in a variety of applications. One of the things we can do thanks to this technology is replacing our credit cards with our phones. Google Wallets is an example of this. Not only credit cards, but store loyalty cards etc. can be replaced thanks to NFC.
Radio Frequency Identification (RFID) is the predecessor to NFC. And NFC is a standard, so it has particular specifications. The transmission frequency for data across NFC is 13.56 megahertz and like all other radio signals it travels in waves.
So finally we are seeing good NFC going mainstream with applications of NFC with BlackBerry and Android giving some very awesome APIs for developers. There has been major debate between NFC and QR but I think they will co-exist pretty well. NFC trumps as an easy source of contact-less payment and is also lot more reliable than QR codes but of course there is the additional hardware cost in there.
So NFC tags can exist in anything from stickers to a pen. They can be encoded withany kinds of strings, generally links. We got a good bunch of samples thanks to Rapid NFC and found them pretty awesome! Using a BlackBerry Z10 it could be encoded in a few seconds and scanned in a fraction of a second with there pre-installed app. Please feel free to leave a comment about your views on NFC.
