What Multibanco actually is
Multibanco isn't a specific bank — it's the country's shared electronic payments network, run by SIBS, which every major Portuguese bank connects into. According to SIBS's own account of the network's history, it launched in September 1985 with nine machines in Lisbon and Porto and has grown to roughly 13,000 machines nationwide, handling, by SIBS's own 2024 figures, more than 693 million transactions in a year.
What makes Multibanco unusual compared to a typical foreign ATM network is how much it does beyond withdrawing cash. SIBS states that more than half of transactions on the network in 2024 were non-withdrawal operations — bill payments, government payments, transfers and mobile phone top-ups among them — which is why Multibanco machines are found inside supermarkets, universities and public buildings, not just outside banks. As a visitor, this mostly means one thing in practice: any machine branded Multibanco you encounter in a shop or transit hub is a legitimate, standard part of the payments system, not a private or unusual terminal.
Card acceptance in Lisbon
Card payments, including contactless, are broadly accepted across restaurants, shops, transit ticket machines — including Lisbon's Navegante card machines — and most tourist-facing businesses in Lisbon. This guide can't responsibly generalize that to every small business or every neighborhood, since acceptance at any individual vendor is that vendor's own decision — carrying some cash remains a reasonable backup, particularly for small markets, some older cafés, and specific machines like street parking meters where a particular card type occasionally fails to work.
Getting cash the right way
If you need cash, a Multibanco ATM attached to a bank branch is generally a safer bet than a standalone ATM in a heavily touristed area, purely because standalone machines in dense tourist zones are more likely to charge higher withdrawal fees or push harder on currency conversion offers, discussed below. Your own bank's foreign transaction and withdrawal fees apply regardless of which Multibanco machine you use, so check those terms with your bank before you travel rather than assuming Multibanco itself charges you directly.
The dynamic currency conversion trap
This is the one payment decision in Portugal that actually costs visitors money if they get it wrong, and it's an EU-wide issue, not something specific to Portuguese machines.
When you pay by card or withdraw cash with a non-euro card, some terminals and ATMs offer to show the amount — and charge you — in your home currency instead of euros. This is called dynamic currency conversion (DCC), and the exchange rate applied is set by the terminal operator or the DCC provider, not by your card network or your bank, and it is very often worse than what your own card issuer would apply if you let the transaction go through in euros.
EU regulation requires transparency around this choice rather than banning it outright. Under the EU's cross-border payments framework, as summarized by the EUR-Lex database of European Union law, providers offering currency conversion at ATMs or points of sale must disclose the total currency conversion charge as a percentage markup over the European Central Bank's reference rate, and must show the amount payable in both currencies, with the choice of which to pay in, before the transaction is completed. In practice, this means the machine has to tell you the terms and let you choose — it doesn't mean the rate on offer is good.
Contactless limits and PIN
Contactless card and phone payments are standard for smaller transactions across Lisbon, though individual banks and terminals set their own contactless limits before requiring a PIN, and those limits vary by card issuer rather than being fixed nationally. Bring your card's PIN regardless of how often you plan to use contactless — a terminal or ATM can request it at any point, and not knowing it can strand you at exactly the wrong moment, like an unattended fuel pump or a parking garage exit machine.
What this guide does not cover
This article doesn't cover opening a Portuguese bank account, foreign transaction fee comparisons between specific card issuers, or the tax refund process for non-EU visitors, all of which are separate questions with their own rules. Check current ATM withdrawal limits and any fees with your own bank before you travel, since those figures are set by your issuer, not by Multibanco or SIBS.
