How to add a credit card
Simply go to Settings -> Payments -> Credit cards and, in the top right corner, click Add a card. There, you will see a form you need to fill out with your credit card data.
Once you’ve done this, go over to the column, Actions, and click the icon Click to mark as a default card. This way, User.com will be able to renew your subscription automatically.
User.com accept only MasterCard and Visa types or cards.

Note that User.com doesn’t store your credit card data. We store them inside Braintree (a PayPal company).
