+## Working with saved cards 
+
+When you enable saving a card, a Save Card checkbox appears on the payment form. If the user checks this box, the SaveCard flag will be set to true and passed to your onCreatePayment handler. You can then store the card details in your backend.
+
+During future checkout sessions, include the user’s previously saved cards via the savedCards array in the card payment method configuration. When a saved card is selected, the SDK uses it for the payment process. If the user decides to remove a saved card, the onDeactivateSavedCard callback is triggered, letting you remove or deactivate the card from your backend.
