You’re bound to have seen them around – those little black-and-white pixelated squares that seem to be cropping up more and more often lately. But just what are they? QR codes, or mobile tags, is the answer. A QR (that’s Quick Response) code is like a barcode that can be read by applications on certain mobiles and smartphones that, when scanned, will take you directly to a mobile version of a website (you can try it for yourself here).
The codes were created in Japan and are now becoming very popular in Europe too. When scanned by a reader (easily downloaded onto iPhones and Android devices and often pre-installed on many mobile platforms), the codes can lead to a mobile website, location information, a voucher code or special offer, contact details or even a trailer for a film. They can carry several hundreds of times the amount of data carried by ordinary barcodes thanks to their ability to be read in both horizontal and vertical directions.
QR codes can now be found on t-shirts, posters, business cards, the sides of buildings (see the skyscraper in Tokyo that has been turned into a giant QR code) and have even started to be used as artwork. They are being used more frequently in the gaming world, where players of the PlayStation 3 game Little Big Planet 2 can generate and print a code for every level in the game, and hold the code up to the PlayStation Eye camera to be taken directly to that level. The Nintendo 3DS Mii Maker application can generate a code for any Mii so that it can be published or shared on the internet, and the game Defense Grid: The Awakening (used in the Portal 2 ARG campaign) even has a level shaped like a QR code.
Any business can take advantage of the new technology and show off their tech knowledge through the use of a QR code. Add them to your posters, business cards and promotional material and give customers quick access to product details, contact information and special offers. The codes can be easily generated using sites such as Kaywa, and it’s even possible to add a logo into the code (provided your code has a high enough error correction margin).
