Up-to-date contact information: important for your card security
You should report any changes to us immediately. On the one hand, up-to-date contact information is crucial for card security, for example, if we want to make sure that a card payment is legal. On the other hand, we need your cell phone number, for example, for online payments with 3-D Secure and the Swisscard app.
