Before you choose

Consider

imKey ProSetup starts in imToken, and COS firmware updates require USB to a computer. Save the binding code for pairing with a new phone; it is separate from the recovery phrase.

Tangem RingTake the ring off to scan. You review payments on the phone; Ring has no independent screen. Choose seedless or phrase backup during setup.
