Code Muncher scans and reads QR codes in real time by simply pointing the BlackBerry camera at a QR code and taking a picture of it. Upon recognition of a QR code, the application will instantaneously process and decode the image. Users can view web sites, send SMS messages, call phone numbers, and save contact information from QR codes.
Motek mobile has two versions of Code Muncher available: a free, ad supported version and a paid version for just $.99. There are some options built in to the app to customize it, such as different sound effects while scanning and different colors for the little muncher guy. Overall, the app does what it says, and you can't beat free. The only catch is that so far Code Muncher is only available for the BlackBerry Bold 9780 and Torch 9800, BB6.
