Not a bad option, although now we need a phone with camera, a printer, a QR reader app, to name a few…
And don’t let get started with usability issues of QR codes (like restaurant menus)

My idea is to make it easy to backup keys with pen and paper 🖋 📄 without copying the hexadecimal string which is prone to error 👀
