# How Do I Change My Payment Card Details?

To add a card to your account, or update your card details you will need to visit your [Krystal Client Area](https://krystal.uk/client/).

1.  From the **Billing** menu, click on **Manage Payment Card**.

2.  If you have a card on file, you'll be able to delete it by clicking **Delete** - but be aware that if you do this, we will no longer be able to collect automatic renewals until you add a new card.
