Expense and Subscription Cards use the real-time Visa exchange rate service. This means transactions are made based on the currency exchange rate at the time the transaction is made.
You can view the Visa Currency Converter on the Visa website.
Note: When using the Visa Currency Convertor, the 'Transaction date' is the day that you made the transaction (not the cleared date). The 'Bank fee (%)' field should be set to 0%.
