Decoding with other 2D Barcode

To allow other 2D Barcode than the Kaywa Reader to decode generated QR-Code you cannot use shortcode (just the QR-Code number). Instead you must add the link http://d.kaywa.com/ in the DATA. Here is an example:

http://qrcode.kaywa.com/img.php?d=http://d.kaywa.com/2029998765
