So who has heard of NFC? NFC I hear you say....National Federation of Call Centres? National Federation of Children... hardly? Not for Christmas? Ok so how about Near Frequency Communication? So at this stage you're either saying, "What the hell is that when it's at home?" or "Yah I wasn't born yesterday of course I've heard of NFC!" Well up to eight months ago I was one of the - "What the hell is that when it's at home?" - people. I had stumbled across it because of a talk I gave on business opportunities using QR Codes back in January which led to my meeting other people who were thinking of opportunities surrounding QR Codes and, well NFC devices. Just to bring everybody up to the same level of understanding here I should point out, for any of you who might be dazed and / or confused, what exactly we mean by QR Codes. Quick Response or QR Codes according to Wikipedia is:
"... a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols).
Created by Toyota subsidiary Denso Wave in 1994 to track vehicles during the manufacturing process, the QR code is one of the most popular types of two-dimensional barcodes. It was designed to allow its contents to be decoded at high speed.
The technology has seen frequent use in Japan; the United Kingdom is the seventh-largest national consumer of QR codes."
Irish readers will be familiar with QR Codes in their national papers, such as the property section in the Irish Independent newspapers. So NFC devices are, in effect, the electronic 'data chip' equivalent of QR Codes. Instead of a visual triger, an embedded computer chip pushes data to a 'reader'. Wikipedia describes NFC thus:
"Near field communication, or NFC, allows for simplified transactions, data exchange, and wireless connections between two devices in close proximity to each other, usually by no more than a few centimeters (Near Field)" and "Many smartphones currently on the market already contain embedded NFC chips that can send encrypted data a short distance ("near field") to a reader located, for instance, next to a retail cash register. Shoppers who have their credit card information stored in their NFC smartphones can pay for purchases by waving their smartphones near or tapping them on the reader, rather than using the actual credit card."
If any one has any experience using a passive NFC device for any particular purpose or knows of any examples please leave a comment. It's quite likely that I will have more to say about QR Codes and NFC opportunities in the future.
