If you can use qr code on coldcard mk4 why even own 9volt battery, SD card etc?

No you can't,
SeedSigner & Foundation you can.
Is this not the cold card doing QR code?
This is from one year ago, so the UX has improved 100x but this is what I'm talking about.
Thanks, I don't know if my link went through earlier. I think this is the coldcard also doing that?
