Payments may be made by PayPal and by Visa, Mastercard or American Express cards. Credit and debit card payments are handled by the Stripe Payment Gateway, note that I receive none of your card information, it is securely handled by Stripe.
Paypal allows you to pay using various bank cards, as well as with a PayPal balance, so check there to see which is available for payment if you prefer to use PayPal or have a different credit or debit card.
I can also accept payments from Germany via Giropay and from Belgium via Bancontact.
Previously I accepted only PayPal payments, as the major credit and debit cards could also be used by customers via PayPal, but I am trying out the new options for payment. If I like it, I'll keep it, otherwise I will revert to only PayPal handling all payments.
