You can block your Tomorrow card at any time in the app yourself. Just click your personal profile, and then "Card". There you can "freeze" and also "unfreeze" it.

If you don’t have access to your app right now, please contact us quickly via one of our live channels. Our chatbot is available 24/7 and is set up to alert our on-call team in case of a report of a lost card or phone. This way, your card can be blocked as quickly as possible—even outside our regular business hours.
