Yes, it’s important that you pay with a credit card issued in your home country, as we expect our customers to use cards denominated in their local currencies. Your credit card will be charged the amount, and in the currency of, your payment request.
If a different currency is used, your bank will need to convert the funds from your card to the currency selected in the payment request in order for us to receive it. This will result in the charges being taken out of the amount delivered to your institution.
Please note: it is impossible for us to know if a credit card is denominated in any other currency, and additionally, we have no control over the conversion that your bank might perform.
