Just passing these two properties, Brick will automatically give the user the option to make the payment with their saved cards. > WARNING > > Attention > > Only no expired cards will be shown to the buyer, expired cards will not be made available. !\[payment-brick-c\](https://www.mercadopago.com.mx/checkout-bricks/payment-brick-cc-en-mlm.jpg) To learn how to create, modify and get the \`customerId\` and \`cardsIds\`, see the \[Cards and customers management\](https://www.mercadopago.com.mx/developers/en/docs/checkout-api-payments/customer-management) section of the Checkout API documentation.
