Update your existing credit card information
If your existing credit card needs to be updated (expired, stolen…), you can do so in your customer space. First, login to https://account.vates.fr and then select "Credit card information" in the left menu.
From there, you can change your card information, or even removing it!
Add your credit card
If you don't have a credit card registered, you can add it by following the same instructions than the previous paragraph. You'll find a button "Add a new card".
