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 someoneâs t-shirt.he 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.
QR Codes can be used to open a location on a map and direct you to it using Waze, to open a Facebook, Twitter or LinkedIn profile page automatically, to share a link or text via all social networks mentioned above, and even call a number using Skype.
