Possibilities are endless with QR Smartphone applications
Quick Response codes are barcodes that you can scan with iPhones, Androids, and a large variety of Smartphones, by using a (usually) free application. After scanning the barcode with your Smartphone's camera, the QR code then magically gives you further information on the relating product by taking you to a website, showing you a video or some pictures.
One of the most successful and prominent ways of using QR technology is in product advertising and marketing. An abundance of media has taken to incorporating QR codes, including: billboards, business cards, tickets, coupons, print adverts, websites, and competitions. If you're reading an article in a magazine or newspaper and there's a video that relates to the topic, QR codes make it possible for you to interact with the magazine or newspaper – while the video can't be included in the pages of the magazine, by scanning the QR code, you can watch the video on your phone. Another use is in providing product information – if you're browsing new laptops, there's only so much information that can fit on the display cards, but by scanning the QR code, you'll be taken to a page that has the full specification of the product.
Recently at Austin, Texas, indie-rock music festival South by Southwest (SXSW), they employed QR code technology so attendees could network and socialise after meeting one another. Each festivalgoer had a QR badge, and if they met somebody they wanted to stay in touch with, they could scan their barcode badge, which acted as an interactive 'follow me' button, connecting to their contact information or sending them a message. Similar practices have since been followed at other events.
Italian artist Fabrice de Nola was using QR barcode labels as early as 2006, when he incorporated them into oil paintings and photographs. Other artists have since adopted this technique in their work. Webcomics are available made entirely out of QR codes, such as a version of Isaac Asimov's short story The Last Question. Pop artists have integrated QR codes into their artwork and music videos, with the Pet Shop Boys and Kylie Minogue among those to use the advanced technology.
