Near Field Communication
Transcript of Near Field Communication
(Near field communication) WHAT IS IT? WHAT CAN IT DO? WHAT WILL IT DO? But, that sounds a lot like Bluetooth technology, right? NFC Why should we care about NFC? NFC is a lot like Bluetooth but with a few differences. NFC has almost instantaneous connection times, a much lower power consumption, and a smaller range (less interference) of 4 to 20 centimeters.
The data transfer rates are faster with Bluetooth (723kb/s) than NFC (424kb/s) but the faster set up, lower power usage, and closer range and versatility of NFC bridges the gap of speed.

So, what about those real world applications? NFC (Near field communication) is a data transfer protocol for mobile device. It was born out of RFID (Radio frequency identification) standards and is in use in many smartphones, tablets, laptops, and even some desktop models. The simple technical explanation: NFC uses electrical circuits to share power and data over a very short distance via internal radios. In most cases, the reader and the writer need to be touching to initiate the transfer. Mobile payments is what the mainstream media and tech blogs are pushing as the major use for NFC, and that was the original intent; If you have a smartphone you can turn it into a wallet, further consolidating your tech toys. However... The problem with mobile payment technology is that it has not been adopted en mass on the retail side. Only Master Card and Citi Bank have jumped on board and if you do not keep your money with either institution, and your retailer of choice does not have the NFC payment readers, you are out of luck. There is still data transfer for NFC to hold on to. Being able to touch two devices together and instantly give a picture or video to a friend is a slick addition to a feature packed device. The mobile operating system Android, uses the data sharing side of NFC to great advantages. They created Android Beam, that if enabled, handles every last detail of the minimal setup and transfer process; passing your data along with just a single press of the screen. Some of the future applications, and some that are in their beta testing stage: (1) The city of San Francisco is starting a trial to allow people to use their NFC enabled phones to "tap and pay" for parking around the city. (2) Although RIM's BlackBerry line of phones is on the decline in popular culture, a massive amount of businesses still rely on RIM for communication. BlackBerry Tag is an application that will allow BlackBerry users to share anything from documents to business cards with other BlackBerry users. (3) Many manufactures of Bluetooth headset and wireless speaker systems, are testing ways to set up (or pair a device) with NFC. You would be able to take a brand new head set out of the box, tap it to your NFC enabled phone and it would automatically connect and go through the set up process. The most exciting application to date is the use of tags to transfer data between your devices, or between a new phone you just bought and your old phone. Sony is on the cutting edge of this possibility and is testing what they are calling SmartTags. They look like a small key fob and can hang from a read view mirror, cubical wall, or beside the toaster in the morning. The concept is simple, when you transition between the car to the office, from your dining room to your bed at night, there are a number of settings you always change: the volume, firing up the GPS, or getting your daily news, ect. You can program the different tags to store all those settings and with a simple touch of your phone you have them all done in an instant! It will most likely evolve into allowing you to touch old and new phones to transfer all your current settings, photos and contacts. NFC is simple, progressive, convenient, and more importantly; it is personal. We live in a period of time where even our car may someday drive itself for us. Too many people live too much of their time on-line behind the keyboard. While NFC may be just another transfer protocol; it is one that forces the user to interact with another user to share or get data.
That touch, however mechanical it may be, is important. Interacting with more than a dumb terminal or an interactive advertisement is something every developer of future NFC applications should take into consideration.
