If your card is lost or you suspect that it might have been compromised, you can either temporarily freeze it or block it (permanently) by logging into your account, going to Cards and updating the status there.
Option 1: Freeze your card (Temporary) If you’ve just misplaced your card and think you might find it, select Freeze Card. This instantly pauses all spending. If the card turns up, you can unfreeze it just as easily and keep using it.
Option 2: Terminate your card (Permanent) If your card is definitely lost, stolen, or compromised, go to the card's Settings and choose Terminate. This permanently deactivates the card so it can never be used again, and you can instantly order a new virtual card to replace it.
