Desktop QR code reader written in Adobe Air
Simply hold the QR code image in front of your camera and if the code has been read properly, you will hear a beep sound.
The QRreader add-on is cross-platform and it works on Mac OS X, Windows and Linux.
NOTE: QRreader might not work with versions of Adobe AIR older than 3.0. If you are experiencing issues, uninstall Adobe Air >3.0 and install 3.0 instead, which can be downloaded by clicking on this link.
