Works fine

This works fine on my MacBook Pro (early 2011) running Yosemite. Very easy to use. Just launch, hold a code up to the camera, and you have the appropriate web page pop up. You do have to get the code close enough to be large enough to take up most of the space within the guide marks. Also, should avoid glare off the code. All common sense.
