GoKawiilGoogle and Samsung outline steps to lock digital wallets on lost Android phones
Google explains that using Find Hub to mark an Android device as lost will log it out of the owner's Google account and strip all cards from Google Wallet, with an option to show a contact message on the lock screen. If account access isn't possible, users can lock the phone remotely via android.com/lock by verifying their identity and phone number. Samsung devices with SmartThings Find offer a similar safeguard, automatically locking Samsung Wallet and pausing transactions until identity is confirmed.
