# Payment Methods Source: https://staging-docs.aiand.com/billing/payment-methods/ ai& uses Stripe for all card processing. Payment methods are attached to your organization's billing account and reused across top-ups. ## Adding a card A payment method is saved automatically the first time you complete a Checkout. To add additional cards or change the default: 1. Go to [console.aiand.com/settings/billing](https://console.aiand.com/settings/billing). 2. Click **Payment Methods**. 3. Add a new card via Stripe's hosted form, or set an existing card as the default. ## Default payment method The default is used for any future automated charges (e.g. when auto top-up is enabled — coming soon). One-off top-ups always show a method picker. ## Supported payment types - Major credit and debit cards (Visa, Mastercard, AmEx, JCB, Discover). - Other Stripe-supported methods may appear at checkout based on your country. ## Removing a card You can remove any non-default card directly from the billing page. To remove the default card, set a different one as default first.
