QRCode Display Portlet


QRCodes are getting part of our lives day by day. ZXing has a quite good implementation on generating them, so I thought it could be a nice feature to have a portlet to add a QRCode to a page displayed by a portal.

Goals of the project

This project's goal was to let the users to display the portal's URL, the current URL or a custom specified URL or Text in QRCode format on the portal pages.

Below there are some screenshots of the current portlet:
