Current URL QR Code Display
For example, if the module was being displayed on a page
(say http://akshatsinghal.com/urlqrcode), the QR code would be pointing to the
same (i.e. http://akshatsinghal.com/urlqrcode). Snapping this QR Code using a
compatible mobile phone will enable the user to access this page directly
on their device.

QR Code reading software is available for many mobile phones (see http://www.mobile-barcodes.com/qr-code-software/)
and they are commonly used in Japan.
