The same thing that happens to your crypto: nothing, as long as you have your remaining factors. Keevo's Four-Factor Authentication means any three of your four factors — your Keevo device, your password, your fingerprint, and your Carbon Key™ — can restore access on a new device. Your Keevo Card is protected by the same recovery model as your crypto, with no seed phrase necessary and no single point of failure.

And because of that same Four-Factor Authentication, nobody who gets ahold of your Keevo (or your Carbon Key) can access or use your Keevo Card. They would still need your other factors (your fingerprint, your password) to do anything with it.
