In 2026, Portugal is largely a digital-first society, but carrying a mix of both is essential for a smooth trip. Major credit and debit cards (Visa and Mastercard) are accepted at almost all hotels, restaurants, and supermarkets in metropolitan areas like Lisbon and Porto. However, many smaller shops, local cafes, and traditional "tascas" in rural regions still adhere to a "Multibanco" only policy, which often excludes foreign-issued cards, or they may have a minimum spend requirement for card payments. It is highly recommended to carry around €20–€50 in cash for small purchases, local markets, or tips. ATMs (look for the "Multibanco" sign for the best rates) are widely available. When paying by card, always choose to be charged in the local currency (Euros) rather than your home currency to avoid the unfavorable exchange rates associated with dynamic currency conversion.
