Paying for the MRT in Singapore is incredibly convenient for tourists, as the system fully supports contactless payments. You can simply tap your contactless Visa, Mastercard, or American Express card (issued anywhere in the world) or use mobile wallets like Apple Pay, Google Pay, or Samsung Pay at the entry and exit gantries. There is no need to register your card or stand in line at a ticket machine; the "SimplyGo" system automatically calculates the distance-based fare and charges your bank account directly. Note that foreign-issued cards may incur a small administrative fee (usually around $0.60 per day of use). Alternatively, you can purchase a Singapore Tourist Pass, which offers unlimited travel for 1, 2, or 3 days, or a standard EZ-Link card, which you can top up with cash or credit at any station. However, for most short-term visitors in 2026, using your existing smartphone or credit card is by far the fastest and most efficient way to navigate the city.
