QR code

(Quick Response code) A two-dimensional barcode widely used for many purposes. When scanned with a mobile tagging app in a smartphone, it can cause a Web page to download with information about a product, local event or just about anything. QR codes can make mobile payments (see CurrentC), and they can download apps or capture business card data. Codes are found in newspapers, magazines, brochures and store shelves, and billboard-size codes can be scanned at a distance, because the QR app uses the phone's camera.

4K of Alphabetic Data
The QR code can store up to 4,296 alphanumeric or 7,089 numeric characters, and if a high level of error correction is used, up to 30% of the image can be smudged and still be recognized. Created in the mid-1990s by a Toyota subsidiary to track parts on assembly lines, they are widely used in Japan. The technology became an ISO standard in 2000 and gained popularity in the U.S. within the decade.

Google Was a Big Promoter
To promote its local business service, Google sent 100,000 custom-coded QR codes to U.S. establishments in 2009, suggesting they place the code in a prominent location for "mobile tagging." See QR code stickers, barcode and Google Goggles.
