Block and unblock a card

You can temporarily block a card to prevent it from being used in transactions, then unblock it later to restore use. Blocking is reversible - for permanent termination see remove a card.

Block a card

Blocking moves the card from ACTIVE to BLOCKED. Any funds on the card are frozen until the card is unblocked or destroyed.
