This odd little graphic is a QR code. A QR code (Quick Response
Code) is a type of barcode that stores rich information and can
be read by devices, such as smart phones or tablets. It was
created in Japan and initially used for the automotive industry.
The QR codes are currently widely used, and probably you have
seen these on product packaging, in magazine ads, or on
webpages. Find more about QR codes on Wikipedia. How to read QR
codes? The easiest way to read QR codes is through a smart
phone, which will need to have a camera, a code-reading app, and
Internet access. Open your app, snap a picture of the QR code,
and the data linked to the QR code will automatically appear.
The QR code on top of this page is generated using the URL of
