Several payment processors offer prepaid cards to withdraw cash from your account with them at ATM's. Usually these are Mastercard. What is the currecny exchange procedure when you withdraw with a Mastercard? As I know in Europe Mastercard uses Euro billing. So, what happens is when you make a withdrawal, the cash is first converted to Euro, in case your payment processor account is not a Euro account, and then converted to the target currecny, in case it is not Euro either, right? Or during the transaction the source currency is converted directly to the target currency, whatever they are, and that's all?
