My plan is to generate a set of addresses including private keys. Then pipe them through qrencode and print them for save offline storage.
A simple bash script will do fine.
One catch is if you print the ASCII text the QR code is inverted and my ‘untrusted’ android scanner app doesnt read it. Generally a bad idea to scan these codes with an ‘untrusted’ device. Therefore the ‘non-intelligent’ USB QR scanner.
I hope the qrencode parameters will solve the color issue.
--foreground=RRGGBB[AA]
--background=RRGGBB[AA]
specify foreground/background color in hexadecimal notation. 6-digit (RGB) or 8-digit
(RGBA) form are supported. Color output support available only in PNG, EPS and SVG.
But first I have to go to work
