Go to the «Cards» section in the iCornèr App and access your card settings, either by clicking on one of your cards or by selecting the «Settings» icon (if you can’t see it, try clicking on the «Other» icon to see all of the available functions).

Click on the «Show details» button and confirm your identity using Face ID or a digital fingerprint (if biometrics are not activated, you’ll be asked for your telephone unblocking code). You’ll be able to view your card number, expiry date, CVV and cardholder name for a maximum of 60 seconds.
You’ll then be able to copy your card number and CVV by clicking on the blue icon on the right.
