dld.bz is a private URL shortening service.
To generate a QR code for a short URL, append .qr to the short URL.
For example, to generate a QR code for http://dld.bz/BQT, change the URL to http://dld.bz/BQT.qr so when users click on http://dld.bz/BQT.qr they will get the QR code instead of being rerouted to the destination URL.
