From the Krux FAQ:
"Signing operations in Krux are done offline via QR code or via SD card using the PSBT functionality. You can CREATE/LOAD your BIP-39 mnemonic, or import a wallet descriptor, and sign transactions all without having to plug the device into your computer (except to initially install the firmware). It reads QR codes with its camera and outputs QR codes to its screen, or to paper via an optional thermal printer attachment."
I think there's your answer. You'll have to get one and try it out. 🤷
