QRCodes is a Chrome plug-in which will allow you to share links using qrcodes. It works as described above:

a) select one link (or a set of links)

b) click on a single icon from the menu which will open up the link in a new window, and set the link as the background

c) drag and drop the icon from the menu to the right place on the page

d) click the icon again to hide the link and return to the previous screen

The text which is displayed on a qrcode can be changed using a function. Simply right-click on it, then on the "Change color" button and select the text color.

Moreover, the qrcodes for Chrome are configurable: they can be displayed on the top or the bottom of the window. Moreover, you can display more than one qrcode at a time.
