While Amsterdam is one of the most "cashless" cities in Europe in 2026, it is still a "good-to-have" rather than a "must-have." Virtually all major retailers, museums, and supermarkets (like Albert Heijn) accept contactless credit and debit cards, and the city’s public transport (OVpay) allows you to tap in and out with your phone or card. However, you might still encounter small "PIN-only" shops that do not accept certain foreign credit cards, or very traditional brown cafes and street stalls at markets like Albert Cuyp that may have a minimum purchase amount for card use. For these instances, carrying €20 to €50 in small bills is a smart safety net. It is important to note that some establishments in Amsterdam have gone completely "No Cash," and will not accept coins or bills at all. For travelers, the best strategy is to rely primarily on a card with no foreign transaction fees but to keep a few Euros tucked away for emergencies or for small tips for street performers and canal boat crews. Also, remember that Amsterdam uses the Euro (€), and using local ATMs (avoiding "Euronet" machines which have high fees) is the cheapest way to get cash if you truly need it.
