Question.... Does the QR code scan.......
I saved the image from the OP to my camera roll on my iPhone.
When I open the photo in QR Reader it automatically detected the QR and showed the public key so I think it's fair to say that it does
The only reason I say this is because it is reversed.... everything that should be black for QR is White...
Originally the QR code was just done for cosmetic design reasons.
However I have just checked it using "QR Code Reader" on Android and it reads perfectly when scanned directly from the crystal
