With the recent RIM BlackBerry Messenger 5.0 launch, BlackBerrys will have a native built-in SPARQCode scanner.  One of the most popular uses for this scanner is to exchange BlackBerry PIN Contact information.  The SPARQCode generator Maestro has been enhanced to support this functionality so BlackBerry users can now create a PIN SPARQCode and add them to their business cards, websites, or any other media.  BlackBerry SPARQCodes can be created under the MeCARD tab in Maestro.
