Just what I was looking for.

I spent some time trying to find an app that would read a QR code on my iMac or MacBook air without having to use the isight camera. If I receive a QR code in an email, it is usually in the form of a png or pdf file. Spent well over an hour on Google until I came to this app…. Downloaded it and it does exactly what I wanted. Drag the image to the app and it opened the URL correctly. Just great and works… Now to see if there is one like this for the iPad. That would make my day as they say...
