Payer cards belong to specific payers and can be used to make payments. Add a payer cardId to a payment creation call to use the card as a source of funds for the payment.

Creating card resources implies that client system has card data. As a result Paystand will only sanctify creating cards from PCI DSS Compliant systems. The Card resource allows you to update, and retrieve card details. Use the [Create a payment (authenticated)](https://developers.paystand.com/reference/create-payment) endpoint to create a payment with a card on file by providing a cardId. This feature is available depending on your plan.
