The **Payment methods** tab holds the card your studio uses for **automatic plan renewals**. Save one here and Qwacks charges it when your [plan](/qwacks/billing-plans) renews, so your limits never lapse between months. ## Adding a card Add a card by entering its details. They go straight to **Moyasar**, Qwacks's payment processor — Qwacks never sees or stores your full card number, only the safe display details like the brand, last four digits, and expiry. Moyasar may send you to your bank to confirm the card with 3-D Secure; once you're back, the card is saved to the studio and set as its **default**. Your **default** card is the one charged at renewal. Saving a new card makes it the default, and you can remove a card whenever you like. This card is for **recurring** renewals. Paying a one-off [invoice](/qwacks/billing-invoices) — like your first subscription charge — happens on a separate secure page at the time of payment and doesn't need a saved card.
