For car rental bookings, credit card is the main form of payment as it is required for a security deposit at time of pick-up.
Pre-paid and debit cards (e.g Maestro and Visa Electron) are not accepted by car rental suppliers as payment. Cash payments are also not possible.
Please note that Visa and MasterCard are accepted by all car rental suppliers, but AmericanExpress is not as widely accepted. Please check at time of reservation what is accepted.
