How to block my N26 card?

You can block and unblock your cards at any time in the app. Go to 👤 My Account and select Card settings. There you can decide if you want to temporarily limit or disable your ATM withdrawals, online payments or payments abroad, or block your card entirely.

This way, you have full control of your card and can protect yourself against unauthorized transactions. You should immediately block your card if anything looks suspicious. You can always unblock it later.
