What is this? This is a QR Code: a machine-readable image-based code consisting of black (or any non-white
color like green in this case) and white squares. QR Codes are typically used for storing URLs and other
information for reading by smart devices like smart phones. When scanned by an appropriate app on your mobile
device, you are redirected to the embedded URL of this page. View this page with one device (desktop or another
mobile device), and then scan the QR Code with your mobile device. This makes it quicker and easier to browse
a page discovered on one device on your mobile device without manually entering the URL in the mobile device
browser address bar.
