QR Codes - What are they? How could they be used? Can I make one?
QR is short for Quick Response (they can be read quickly by a mobile phone). They are used to take a piece of information from an advert or document and put it in to your phone. You often see QR Codes in magazine adverts, on billboards, web pages or even on someone’s t-shirt! Once it is in your 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 voucher which you can use in a local shop.
