The official currency of Singapore is the Singapore dollar. Credit cards are widely accepted in restaurants, bars, shops, hotels and taxis in Singapore.

Singapore is a world leader in "cashless" high-fidelity payments, and you can pay for almost everything using a contactless credit or debit card (Visa and Mastercard are ubiquitous) or a mobile wallet like Apple Pay and Google Pay. For public transportation, you can simply "tap" your contactless card or phone at the MRT (subway) gantries and on buses—there is no need to buy a separate ticket. Another popular local option is the EZ-Link card, which can be topped up at stations and used in convenience stores. While digital payments are the norm in malls, hotels, and restaurants, cash is still highly recommended for "Hawker Centres" (open-air food courts) and small neighborhood shops, as some stalls may only accept cash or local QR-based payments like PayNow (which usually requires a local bank account). For a tourist in 2026, the best strategy is to rely on your phone's mobile wallet for 90% of transactions but keep about $50 SGD in small denominations for those iconic street food meals and traditional market finds.
