Can the deposit be retained on a debit card?

A deposit will be required for the vehicle itself. It is intended to cover any additional cost or light damage incurred during the rental period. Its amount depends on the vehicle category. Your bank card must have sufficient funds to cover the rental and the security deposit amounts. If you use a debit card, the amount will be debited from your bank account. If you use a credit card, the amount will be blocked on your bank account and unusable for the duration of the rental period. No other means of payment is accepted for the security deposit.
