Both Stripe and PayPal accept international credit cards. The transaction fees they charge are, however, a little higher than fees placed on domestic cards.

• Stripe adds an additional 1% on top of Stripe’s standard nonprofit rate of 2.2% + $.30 for most major credit cards and 3.5% for American Express.
• PayPal charges a 3.49% transaction fee plus a fixed fee based on the currency received.
  

Note that, at this time, the ability for donors to cover the fee does not apply to the international currency conversion part of the transaction, so there will be a slight difference between the fee-covered donation sent and the total amount received by the nonprofit.
