The QR code is a square with a black and white design and placed on a print advertisement or a placard, say, at a transit station, people can use their mobile devices to scan the code and access a website for more information or a discount on a purchase. UW-Madison has started experimenting with QR codes in some venues, such as the Chazen Museum of Art, wgere an exhibit of Russian icons last spring included QR codes on the labels of many objects, leading to pages on the art history department?s website with research by students on the works of art. The athletic department posted a QR code online, in addition to a link, for the Badgers? spring football game, packed with information about the team, while the Wisconsin Sea Grant printed QR codes on postcards distributed to outdoor outfitter stores.
Quoted: UW-Madison communications professor Dietram Scheufele, who said QR codes are ?very successful tools” and could one day be used by students to register for classes.
