QR Code plugin for Wordpress

Hi I would like to know if there is a QR-Code Generator plugin available with wpmudev ? i am using free QR code plugin from wordpress.org. i would like to display on each page a QR code which will link to the page on the mobile phone. The user help of the plugin says i may use it by using the short code

[qrcode content="CONTENT" size="120" alt="ALT_TEXT" class="CLASS_NAME"]

how can i replace the "CONTENT" with each pages url instead ? and the "ALT_TEXT" may be replaced with the page title.
