Is there any monthly or annual fee for EntroPay Accounts?
There are no monthly or annual fees with an EntroPay Virtual Card. Our only fee is the 4.95% charge on each amount loaded onto an EntroPay Virtual Card. There are no hidden fees.
Return funds from EntroPay Account to personal credit/debit card: we charge a GBP3/USD6 fee as outlined in our Terms and Conditions.
There is no minimum withdrawal amount. Your balance must however be sufficient to cover the GBP3/USD6 withdrawal fee.
