Yeah, I was thinking it would be hard to store that amount of data in QR code even if image quality was reduced.
My cousin had an idea to make (print) an album but wanted to do it with QR codes because it would be cheaper to print (only black and white printing is required).
True, but if internet connection for some reason crashes in some part of the world you still can’t use crypto there, so cash is still not useless (and probably shouldn’t ever be).
