if you had to rank the security of the various connection methods that hardware wallets use today, how would you rank the following?
  • bluetooth
  • nfc
  • usb
  • microSD
  • camera
  1. MicroSD
  2. Camera
  3. USB
  4. NFC
  5. Bluetooth
Why is the MicroSD safer than the Camera? Isn't the autorun* ability of the card an attack vector?
[*] Is it still a thing on Windows?
It's debatable if the USB driver is worse than QR and bcur decoders
Camera is likely better - since it allows you to communicate with your companion app only when you choose for it to. Less likely to be attacked
