As they say it is all in the fine details. If you try to rent a vehcile anywhere with a debit card there are restrictions where the rental company could ask for a credit card as well.
F. Credit Qualifications/requirement: To qualify to rent the DOLLAR vehicle, the renter must present at the time of rental a major credit card or debit card (See Debit Card Usage below) in the renters own name with available credit. A hold will be placed on the renters credit card for the estimated amount of the rental plus 15% or a minimum amount, whichever is greater, as determined by the location where you intend to rent. The hold will be removed at the end of the rental when the final charges are settled. Because the requirements vary by location, please refer to the Local Policies for specific information on credit qualifications and requirements where you intend to rent a DOLLAR vehicle.
G. Debit Card Usage: If the customer presents a debit card at the beginning of rental to qualify to rent, we will perform a debit card check and credit inquiry screening through Equifax Credit Information Services, Inc. This type of inquiry will screen out customers who present a greater driving risk to us, using a standard set of criteria. In the event that a customer's debit card check and credit inquiry fail to meet our debit card criteria, the customer will not be allowed to rent unless they provide a major credit card in their own name. Our debit card policy complies with all applicable U.S. federal and state laws. Debit cards are accepted for payment at the end of rental without a credit inquiry. Debit cards may not be accepted in Canada except for payment at the end of rental. Since credit requirements vary by location, please refer to the Local Policies for specific information on the acceptance and usage of debit cards where you intend to rent a DOLLAR vehicle.
