You can use Visa, MasterCard, Diners Club, or American Express to make PayPal payments. If you've used your credit card to shop on an international website in the past, you should be all set.
Once you've linked your payment method, you'll never enter your account numbers again. You'll pay with just your email and password—this is the key to secure and simple payments.
If you're currently earning points or miles through your credit card, you'll continue to earn those points when you use that card with PayPal. Plus, you can register for additional benefits, like Return Shipping on Us.
