Your account will be billed in the currency you choose when making the transaction..
When making a payment, the transaction currency will be automatically detected. If it is one of the 30 currencies corresponding to the accounts in your account, the amount will be debited from the relevant account. If, however, it is different than those offered on our accounts, the funds will be automatically converted at the rate offered by MasterCard.
If the funds on a given account are insufficient to complete the transaction, the missing part will be debited from EUR, USD, GBP or PLN accounts and automatically converted at no cost.
