If you are paying in your local currency (ARS), Flywire advises NOT to use a dual currency card.
Why we recommend avoiding dual currency cards: While Flywire only requests the specific amount and currency shown on your booking, your card provider may apply its own currency conversion rules. This often leads to unexpected additional fees or a different exchange rate being applied by your bank.
What should I do? To ensure your payment is processed as expected, we recommend using a standard local currency card. For more details on potential fees, please check the terms and conditions provided by your card issuer.
