Last-Minute or Walk-Up Car Rental in Portugal: The Card Rule Doesn't Bend

Booking a car the same day, or turning up at the airport desk without a reservation, is possible in Portugal — but it removes your safety margin. The deposit is a pre-authorisation held on a card at pickup, and the card requirement is the same whether you booked three months ago or three minutes ago. If the card is refused, you have no time to order another one, raise a limit or switch company.

What matters is knowing the card rule before you choose a company. Per the terms this site verified in July 2026, Goldcar, Centauro and Record go accept a physical, nominative debit card for the deposit; Cael, Guerin, Europcar and OK Mobility require a physical credit card; Sixt depends on the booking. For a last-minute rental, filter by that first and by price second.

Which companies actually work

  • The card rules are identical for last-minute and advance bookings — the deposit is held at the counter against a physical card in the main driver's name, and being in a hurry doesn't change that.
  • With only a debit card, look first at Goldcar, Centauro and Record go (physical, nominative debit accepted for the deposit per terms verified July 2026) — the other companies this site tracks would refuse it.
  • With a credit card, check that its available limit covers the full deposit for the car group, with room left for the rest of your trip — you can't ask your bank for a temporary increase after the desk has already declined.
  • Bring the physical card, the main driver's licence and passport or ID. A phone wallet or a photo of a card is not a substitute for the physical card.
  • A deposit-waiver cover bought online (Super Relax at Goldcar, Smart Cover at Centauro) drops the deposit to €0, which removes the card requirement; check the company's own terms for whether it can be added on a same-day booking.

Step by step

  1. Decide your card situation before comparing prices: credit card, debit card only, or neither. That narrows which of the eight companies can realistically fulfil the rental.
  2. Open the company's own terms (linked from this site's comparison table) and confirm the accepted deposit card type for your booking route, especially if you book through a comparison site.
  3. Book online rather than relying on desk availability where you can, even if it is only an hour before you land — that lets you see the card terms in writing before you commit.
  4. Check your card's available balance or limit in your banking app and, if you're close to the deposit amount, use a different card or pick a lower car group.
  5. If the desk refuses the card, don't cancel on the spot — that can count as a no-show. Ask for the refusal and the reason in writing, cancel by email the same day, and take it up with your card issuer if you were charged.

Frequently asked questions

Can I rent a car in Portugal at the airport without a reservation?

Desk rentals can be possible depending on the company and availability, but this site doesn't track walk-up availability. The deposit-card rules in each company's terms apply regardless, so check them first.

Is the deposit smaller or the card rule looser for a last-minute booking?

Don't assume so. This site tracks the card type each company accepts for the deposit, not how the booking was made, and nothing in the terms it verified in July 2026 relaxes the rule for same-day bookings. Read the company's own terms for the amount and conditions.

I only have a debit card and I'm booking tonight — what now?

Per terms verified July 2026, Goldcar, Centauro and Record go accept a physical, nominative debit card for the deposit. Confirm in writing with the company before you travel, and make sure the card's daily limit can cover the hold.

Can I book on arrival and sort out a credit card later?

No — the deposit is taken at pickup, so the right card has to be with you at the counter. If you don't have one the company accepts, the rental can be refused.
