You might think getting around Korea means a different ticket for every city and every ride — in fact, locals do it all with one small card. The T-money card is Korea’s rechargeable transport card: load money onto it, tap in, tap out, and it covers subways, buses, taxis and even convenience-store purchases nationwide. Buying one takes about two minutes, and this guide walks through exactly how to buy it, charge it, use it and refund it before you fly home.
What Is a T-money Card?
T-money is a contactless smart card that works on subways and buses in Seoul, Busan and virtually every other city in the country, so one card really does cover an entire trip. Each ride costs slightly less than a paper single-journey ticket, and — far more importantly — it unlocks free transfers between buses and subways, which single tickets never do. There is no registration and no ID check: you buy it, charge it and tap. The T-money official site has an English overview of everywhere it works, but the short version is: almost everywhere that moves.
Where to Buy a T-money Card and How to Charge It
This is a two-minute errand you can run at the first convenience store you pass after landing:
- 1. Buy the card at any convenience store. GS25, CU, 7-Eleven and emart24 all keep them at the counter. A basic card costs around ₩3,000 (character editions cost more) and comes with a zero balance — charging is a separate step.
- 2. Charge it in cash at the same counter. Hand the card over and name an amount. Loading ₩10,000 comfortably covers a couple of days of city travel.
- 3. Or top up at a subway station machine. Every station has charging machines with an English menu; most accept cash only.
- 4. Tap in, tap out. Touch the reader as you enter and again as you leave — that is the entire system.
Top-ups are cash-first for foreign visitors, so withdraw some ₩10,000 notes early in the trip. And if your balance runs dry mid-journey, the exit gate will beep you back — every station has an adjustment machine inside the gate line where you can top up and tap out.
T-money Card Fares vs Single-Journey Tickets
As of 2026, a base fare on the Seoul subway or a city bus is around ₩1,400–1,500 with a T-money card, with a small distance supplement added on longer rides. Here is how that stacks up against buying tickets one ride at a time:
- Subway base fare: around ₩1,500 with T-money; a single-journey ticket costs around ₩100 more, plus a refundable ₩500 card deposit you have to reclaim at a machine after every single ride.
- Transfers: switch between bus and subway (or bus and bus) within about 30 minutes and the next leg is free or heavily discounted. Single tickets get no transfer benefit at all.
- Buses: many city buses no longer accept cash on board, so a transport card is effectively required anyway.
One habit to build immediately: always tap out. Subway exit gates force you to, but on buses it is easy to forget — tap the reader by the rear door as you step off, because that is what registers your transfer discount for the next leg. The Seoul Metro English site has the full network map if you like planning your routes ahead.
Taxis, Convenience Stores and Everything Else
T-money is not just for public transport. Taxis in Seoul, Busan and most other cities accept it — just tap the reader at the end of the ride, as covered in our guide to taking a taxi in Korea. The card also pays at most convenience stores, at vending machines and luggage lockers in subway stations, and even at some cafes and bakeries; VisitKorea’s transportation cards page covers the fine print. And because the same system runs nationwide, the card travels with you — it works the moment you step off the train for a 2-day Busan trip.
How to Refund Your T-money Balance
Before you fly home, you can get whatever is left on the card back:
- 1. Stop topping up a few days before departure and let the balance run low — this makes the refund trivial.
- 2. Refund balances under ₩20,000 at any convenience store. You get cash back on the spot, minus a service fee of around ₩500.
- 3. Larger balances need the T-money headquarters near Seoul Station, so it is simpler not to end up there — see step 1.
- 4. The card price itself (around ₩3,000) is not refundable — but T-money cards never expire, so keeping yours for a future trip is a perfectly good option.
Good to Know
- One card covers the whole country — Seoul, Busan, Incheon, Daegu, Gyeongju and beyond all run on the same system.
- The all-stop AREX airport train and the airport buses at Incheon take T-money, so the card starts paying off the moment you land.
- Buy it on arrival day — it is step one of our 3 days in Seoul itinerary for a reason.
- Discounted child and teen fares exist but require registration; as a visitor, just use the standard adult card.
- T-money keyrings and watch straps are sold everywhere, but the plain card does everything — pair it with the apps in our Korea travel essentials checklist and you are fully set up.
Where can I buy a T-money card?
At virtually any convenience store (GS25, CU, 7-Eleven, emart24), at ticket machines in many subway stations, and at convenience stores inside Incheon Airport. Expect to pay around ₩3,000 for the card itself, then charge it separately.
Can I top up a T-money card with a credit card?
Generally no — counter and machine top-ups are cash-first, and foreign credit cards rarely work at the charging machines. Treat T-money top-ups as one of the few things in Korea you still need cash for.
Does a T-money card expire?
No. The card and any balance on it stay valid indefinitely, which is why keeping it for your next visit often beats queueing for a tiny refund.
Buy the card at the first convenience store you pass after landing, load ₩10,000 and forget about tickets for the rest of your trip. It is the cheapest upgrade you will ever make to traveling Korea.
