Last verified: October 10, 2026 · Source basis: primary sources and public-agency information

T-money is one of the most useful payment tools for getting around Korea. For most short-term visitors, it works as a prepaid transportation card for buses and subways and can also be used in taxis and at many convenience stores.

What can a T-money card be used for?

Seoul’s official visitor guide states that T-money can be used on public buses, subways, taxis and at many convenience stores. It is designed as a pay-as-you-go card: you load value onto the card, then the fare is deducted when you travel.

Where can visitors buy one?

Official 2026 visitor transportation guidance lists convenience stores nationwide and customer service offices at subway stations as common purchase points. Availability can differ by location, so if one shop is sold out, try another convenience store or a station service point.

For a standard T-money card, Korea Tourism Organization guidance notes that foreign-issued credit cards are generally not accepted for standard T-money purchase or top-up, so carrying some Korean won cash is useful.

How to use T-money on buses

Tap the card when you board and tap again when you get off. The second tap matters because the system uses it to calculate transfer discounts and distance-based fares.

Visit Seoul notes that transfer discounts between buses and subways are available when the card is used correctly, and that you should scan when getting off the bus even on the last leg if you want the system to record the trip properly.

How to use T-money on the subway

Tap the card at the entrance gate and again at the exit gate. The correct fare is deducted automatically based on the route. If you transfer to another line within the integrated transit system, the card handles the fare calculation.

Transfer discounts

Visit Seoul explains that T-money offers transfer discounts between buses and subways. The standard transfer window is 30 minutes, although transport policies can vary by time and service. The safest habit is simple: always tap in and tap out correctly.

T-money vs the Seoul Climate Card

T-money is pay-as-you-go and works well when you are not sure how many rides you will take. Seoul’s Climate Card short-term passes offer unlimited rides within a defined service area for 1, 2, 3, 5 or 7 days. If you plan many rides inside Seoul, compare the total cost before choosing.

Practical checklist for first-time users

Buy the card at a convenience store or eligible station point.
Keep Korean won cash available for standard card purchase and top-up.
Tap when boarding and leaving buses.
Tap at both subway entrance and exit gates.
Keep enough balance for your next trip.
Use the card consistently if you want transfer discounts.
