I’m sure you’ve heard the buzz in the U.S. about the “new” two-dimensional barcodes, called Quick Response codes, or QR codes. These codes, which look like mini crossword puzzles, were originally created in Japan in 1994 to track automobile parts. As a result of the iPhone and Android smartphone boom over the past year, QR codes are finally catching on in the U.S. Conventions, restaurants, retailers and real estate companies are using them as a way to connect people with information and multimedia content on the internet quickly via mobile devices. To take the code a step further, some industries such as airlines have started to use "green ticketing", using the digital QR code data in lieu of physical boarding passes.
