In 2026, the best way to pay for things in Switzerland is a combination of contactless credit cards and the local mobile payment app, TWINT. While Switzerland is famously high-tech, it still maintains a deep respect for privacy, and "cash is king" is still more true here than in neighboring Germany or France, especially in rural mountain villages or at local "honesty shops" on hiking trails. For most travelers, using a travel-specific credit card (like Wise, Revolut, or a premium Sapphire/Amex) is best because it handles the conversion from Swiss Francs (CHF) at the mid-market rate. You should always choose to be charged in CHF at the terminal to avoid "Dynamic Currency Conversion" scams. Many 2026 tourists also download the TWINT app, which is the national standard for peer-to-peer and retail payments. While Euros (€) are occasionally accepted in major train stations or tourist hubs, the exchange rate offered by the merchant will be poor, and you will receive your change in Francs, so it is always better to stick to the local currency.
