They are used to take a piece of information from a transitory media and put it in to your cell phone. QR codes are huge in Japan and across the East, and are slowly beginning to become commonplace in the West. Soon enough you will see QR codes on product packaging, shop displays, printed and billboard advertisements as well as in emails and on websites.
The scope of use for QR codes really is huge, particularly for the marketing and advertising of products, brands, services and anything else you can think of.
The reason why they are more useful than a standard bar code is that they can store (and digitally present) much more data, including URL links, Geo coordinates, and text. The other key feature of QR Codes is that instead of requiring a chunky hand-held scanner to scan them, many modern cell phones can scan them. The full Wikipedia description is here.
Use in mobile operating systems
QR Codes can be used in Google's mobile Android operating system via both their own Google Goggles application or 3rd party barcode scanners like ZXing. The browser supports URI redirection, which allows QR Codes to send metadata to existing applications on the device. Nokia's Symbian operating system features a barcode scanner which can read QR Codes.
Why should I care about QR Codes?
With as many as half of us now owning smartphones, and that number growing on a daily basis, QR Codes have the potential to have a major impact upon society and particularly in advertising, marketing and customer service with a wealth of product information just one scan away.
How does the cell phone read the code?
The cell phone needs a QR code reader, like this one from Kaywa. It takes literally 1 minute for someone with an iPhone, Android phone or Symbian phone to find and install the reader.
