What they are for and how to use them?
The QR code encodes the link to the web page with the report - the very same web page that you can see it on. If you print the web page with the report (print directly from your browser - it is pretty good), you can later navigate easily to the same web page by scanning the code with your smart phone.
You will need some QR scanner application for it, I use QR Droid, but there is many to chose from.
Another use it to tag coins in your collection. For example if your coin is Czechoslovakia gold ducat KM#14, use the QR code from the bibliography, find appropriate catalog number as on the picture below, then just right click on QR code and save it to your PC - you can print it later together with other codes.
This way you don't need to put any details on your coin holder, like pricing info, simply scan the code with your smart phone and it will bring you to the page where you can check the latest sales for the very same catalog item.
In the future we are planning to improve this so you can create a list of codes you want to print without the need to save it to your PC first, or print codes for the whole catalog or for your inventory.
Try it and you will be surprised how easy they are to use.
