QR codes offer the possibility to add a website link or email address to a poster, flyer or invitation. They serve as a link between the offline and online worlds. The graphic can be scanned with a smartphone, allowing free reader apps to lead the user to the corresponding websites. Now it's very easy to produce a QR code yourself with a browser add-on.
The QR Code Generator for Firefox produces the graphics through the search field on the browser. With the add-on Short QR for Google Chrome, users can produce a QR code for any website and shorten the internet address. At the same time, texts can be graphically encrypted and used as a digital message.
