Key differences
- Coldcard MK4 offers deeper offline workflows with microSD + keypad input, while Passport Core has a more modern UI and built-in camera for air-gapped QR signing.
- Coldcard is more affordable at $167.94 vs Passport Core's $199, though both are Bitcoin-only and open-source with strong multisig support.
