T-money Card Korea: Price, Top-Up, Fares, and When the Climate Card Wins

A T-money card is the first thing most people buy in Korea, usually at the convenience store in the arrivals hall, for a few thousand won. It pays for the subway, city buses in every big Korean city, most taxis and a snack at CU. It also saves money, because single-journey tickets cost more and don’t get transfer discounts. Here’s what the card costs, how to load it when your foreign credit card is no help, and when Seoul’s Climate Card beats it.

What the T-money card is, and where it works

T-money is a rechargeable stored-value card. You tap it on the reader when you board a bus or pass the subway gate, tap again when you get off, and the fare comes off the balance. No registration, no name on the card, no link to a bank.

It isn’t only a Seoul card. The same card works on the subway and city buses in Busan, Daegu, Daejeon, Gwangju and Incheon, on most buses elsewhere in the country, in most taxis, and at convenience stores. Two places it doesn’t work: KTX and other Korail long-distance trains, which need a ticket, and the AREX Express train from Incheon Airport.

T-money card price and where to buy one

A standard T-money card costs ₩3,000 to ₩5,000, according to VisitKorea. Plain cards sit at the low end; cartoon and K-pop designs cost more. The card comes empty, and the price of the card itself is never refunded.

Every CU, GS25, 7-Eleven and emart24 sells them, and so do the ticket machines in Seoul subway stations and the shops at Incheon Airport. T-money also makes two cards for visitors: the T-money Travel Card at ₩4,000, and the Travel Card+ at ₩6,000, which adds a WOWPASS payment balance so the same card can pay in shops.

Older guides still recommend the Korea Tour Card. It has been discontinued. Any T-money card will do.

How to top up a T-money card

This is where visitors get stuck. Topping up T-money is a cash business. Hand the card and a ₩10,000 note to the clerk at any convenience store and say how much to load, or use the recharge machines in subway stations, which have an English menu. Both want won in notes.

We’d put ₩20,000 on it at the start. That covers a dozen rides in Seoul, and there’s a convenience store on every block when it runs low.

iPhone users have a second option. T-money has worked in Apple Wallet since July 2025, but at first it could only be loaded with a Korean card. Since March 2026 the Tmoney app has a sign-up for foreigners that accepts cards issued abroad, including Mastercard, American Express and UnionPay, with a fee on each top-up. Visa isn’t supported yet.

T-money fares in Seoul: subway, bus and transfers

Seoul raised its subway fare on 28 June 2025. These are the fares you pay with the card:

A paper single-journey ticket costs more than the card fare and needs a ₩500 deposit, which a machine gives back at the end. That alone makes the card worth buying on day one.

Transfers are where T-money pays off. Tap off, then tap on again within 30 minutes, and the next bus or subway ride counts as part of the same trip, so you only pay for any extra distance. You can chain up to four transfers. It only works if you tap off buses, which plenty of visitors forget. Since 7 March 2026 there’s also a penalty in the Seoul area: leave the rail network without tapping out and an extra base fare comes off your next ride.

From Incheon Airport with a T-money card

The cheapest way into Seoul runs on T-money. The AREX all-stop train from Incheon Airport to Seoul Station takes the card at the gate, like the subway, and gets there in about an hour. The AREX Express, non-stop in about 45 minutes, needs its own ticket.

The order that works: withdraw won at a Global ATM in arrivals, buy the card at the convenience store next to it, load it with cash, then walk down to the trains.

Climate Card Tourist Pass: when it beats T-money

Seoul’s Climate Card Tourist Pass gives unlimited rides on the Seoul subway and Seoul city buses for a fixed price: ₩5,000 for one day, ₩8,000 for two, ₩10,000 for three and ₩15,000 for five. The card costs ₩3,000 on top, once. Subway station machines sell it, and so do convenience stores near stations.

It only covers Seoul. Rides that end outside the city, the Shinbundang Line, the AREX airport train and airport buses aren’t included, so you’ll still want T-money for the airport run and any day trip.

Whether it pays off is simple arithmetic. Count trips rather than rides, because transfers are nearly free on T-money anyway.

Three trips a day is normal for a sightseeing day in Seoul, and that’s enough to make the 3-day and 5-day passes worth it. The 1-day pass needs a busier day than most people have. Longer subway trips, which cost more than the base fare on T-money, tip the balance further toward the pass.

Getting your T-money balance back

Convenience stores refund a leftover balance, usually up to around ₩20,000, minus a ₩500 fee. Bigger balances go through T-money’s customer centre or a subway service counter. The card price isn’t refunded, so a pretty card is a souvenir you’ve already paid for. If you’re coming back to Korea, keep it and skip the refund.

T-money, WOWPASS or the Climate Card?

Still planning? Check whether you need a K-ETA or just the e-Arrival card, read money in Korea for ATMs and the instant tax refund, and pick your season with the best time to visit South Korea. Tipping comes up at the end of every taxi ride; the answer is in tipping in South Korea.
