Here's a quick guide to get you started:
Use your smartphone to download the necessary software from BeeTagg or Scanlife. Install, then launch the application.
Select "scan", and the phone's camera will be activated automatically. Position the phone so that the graphic (above) fits inside the picture frame and hold it steady while the software is activated. (On some phones, such as the BlackBerry, you may need to take a picture of the graphic.)
Depending on the handset used, this will prompt you to "Open link" or "Go to Web". Follow the prompt to access the Platinum Play Mobile Site.
