You can scan the QR code below on your phone.
QR is short for Quick Response (they can be read quickly by a cell
phone).
They are used to take a piece of information from a transitory media and put it in to your cell phone.
You may soon see QR Codes in a magazine advert, on a billboard, a web page or even on someone’s t-shirt. Once it is
in your cell phone, it may give you details about that business (allowing users to search for nearby locations), or details
about the person wearing the t-shirt, show you a URL which you can click to see a trailer for a movie, or it may give you
a coupon which you can use in a local outlet.
The
reason why they are more useful than a standard barcode 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.
