This simple module creates a block with a #QR Code on a profile view page. The QR Code contains an URL to that profile's page. This allows to easily #share#profile links on mobiles.Also an owner of a profile is allowed to download the QR Code as a png image for a later use. For example share it on some external resources or print it and share it in a real world this way making it very easy for people to reach the profile without necessity to type in a long profile URL/address in their browser's address bar.You can even force it to display your site's logo at a centre.
Its a good Module but i have a little problem: i using the Usernames Module by @MSolutions, in this module users can change ther link to the profile. When i change the link to my profile, the QR Codes have no changes to this link, they show only the old links in QR-Codes
