At Singapore's Changi Airport, you can purchase a stored-value MRT card (known as an EZ-Link or SimplyGo card) at several convenient locations across the terminals. The most reliable spot is the SimplyGo Ticket Office (formerly the TransitLink Ticket Office) located at the Changi Airport MRT Station, which is situated in the basement of Terminal 2 and Terminal 3. This office is generally open daily from 8:00 AM to 9:00 PM. If you arrive outside these hours, you can use the automated SimplyGo Kiosks located near the station entrance, which allow you to buy and top up cards using a credit or debit card. Additionally, you can find EZ-Link cards at the various Changi Recommends booths located in the arrivals halls of Terminals 1, 2, 3, and 4; these booths are often open 24/7. In 2026, many travelers also skip the physical card entirely and use contactless payments (Visa, Mastercard, or mobile wallets like Apple Pay) directly at the MRT gantries, which is often more convenient for short-term visitors as it requires no card purchase fee or minimum balance.
