You can save a new credit or debit card to your Kickstarter account by going to Settings and the Payment methods tab, then clicking “Add a new card”. Payment methods that you save on Kickstarter are never fully stored and can be removed at any time by clicking the “Remove this card” button.
I removed a card from my account but it was still charged
When a saved card is removed from your account this does not automatically remove that payment method from a live pledge. Similarly, if a new card is added to your account this will only replace any existing cards currently in use on live pledges by managing your pledge.
If you'd like to change the payment details for a live pledge you can do so by following the steps in our “How can I change my payment method before funding ends?” article.
