When using your Mastercard we will auto-convert your balance to the currency you are spending in at the best available rate, so you do not have to pre-purchase local currencies. 

The card selects which currency to use in this manner:

• The currency of the payment (e.g. if you are in the EU carrying out a transaction in Euro, we will deduct funds from your Euro balance)
• Your base currency (EUR)
• The next active currency with the largest sufficient balance.

Funds are not taken from more than one currency balance at a time, so if there are no currency accounts with sufficient funds, the transaction will be declined.
