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.
  

At this time, the ability for donors to cover the fee does not apply to international currency conversions, so there will be a slight difference between the donation sent and the total amount received by the nonprofit.
