If you enter your CVV, expiry date, or PIN incorrectly 3 times, your card will be temporarily locked. The lock will automatically lift after 24 hours. No action is needed on your part.
Please note that a temporary lock is different from freezing your card. Freezing is something you do manually in the DPT app. A temporary lock is triggered automatically by the system for security purposes.
Your account and other cards are not affected during a card lock.
