So I have been tempting Jim with a generated QR Code to download his zip Extender File. Not very practical [the attached zip has the generated .png as WB won't allow attaching or pasting]. Should work with your camera, or perhaps you have a 3rd party utility to recognize. Anywhoo.. Jim has a barcode extender and has hinted at adding QR. Hopefully more to come.
