T-money Card in Korea: How to Buy, Load, and Refund It
The card that turns Seoul's subway and buses into a single tap — bought, loaded, and refunded without the tourist mistakes.
You land at Incheon, clear immigration, and walk toward the trains feeling great. Then you hit the subway gate, watch a local tap a card and glide through in half a second, and realize you have no idea how to do that. The single-journey ticket machine wants a ₩500 deposit and exact change. The line behind you is growing. This is the moment almost every visitor meets the T-money card, usually a few minutes too late.
T-money is Korea’s rechargeable transit card. You buy it once, put cash on it, and tap it on a reader every time you ride a subway, a bus, or a taxi. It also pays at convenience stores and vending machines. It removes the single biggest friction of getting around Korea, and it costs less than a cup of coffee to start. Here is how to do it right the first time.
Buying the card
Skip the airport counters that upsell you. Walk to any convenience store — GS25, CU, 7-Eleven, or Emart24 — and say “T-money card, please.” There is one inside nearly every subway station and on most city blocks, open around the clock. A plain card runs ₩2,500 to ₩4,000 depending on the design. Character editions with Kakao Friends or BT21 art sit in a rack near the counter and cost ₩5,000 and up.
One thing that catches people off guard: the price of the card itself is never refundable. Think of the card as a keepsake, not a deposit you get back. You only recover the money you load onto it.
If you want your phone to do the work instead, an iPhone can run a T-money card inside the Wallet app and top it up with Apple Pay using a foreign card. Android users get the same through the Korea Tour Card app. The physical card is still the path of least resistance, and it works in places a phone screen struggles with — like a crowded bus where you are holding a suitcase with one hand.
Loading it with cash
Every subway station has T-money kiosks standing next to the gates, and this is where the machines split into two generations. The older blue kiosks take cash only — ₩1,000, ₩5,000, and ₩10,000 notes, topping up in ₩1,000 units, to a maximum card balance of ₩500,000. The newer touchscreen kiosks, rolling out across the Line 1–8 network since late 2025, take foreign Visa, Mastercard, and UnionPay directly. At a major station you get the card-friendly machine; at a smaller one, keep a few bills ready.
Convenience store counters also load cards — with one catch that surprises people: transit top-ups at the register are cash only, even though the store happily takes your credit card for snacks in the same transaction. Load ₩20,000 to ₩30,000 in cash on day one — enough for two or three days of normal riding — and you’ll never get stuck at a gate with an empty card.
Using it day to day
Subway: Tap the card flat on the reader as you enter, and tap again on the reader at the exit gate. The base fare is ₩1,550 for the first 10 kilometers, then ₩100 more for every additional 5 kilometers. The exit tap is what calculates that distance, so a card that got you in but not out will charge you a penalty next time.
Bus: Tap on the yellow reader when you board. On most Seoul city buses you also tap a second reader when you get off. That exit tap is not optional theater — it is how the system knows how far you rode and, more importantly, how it hands you your free transfer. Skip it and you lose the transfer discount and eat a distance surcharge on your next ride. The base bus fare is ₩1,500.
Listen to the reader, too. A single clean beep means you paid. When you tap during a valid transfer, the machine says “hwanseung-imnida” — “this is a transfer” — and charges you nothing. A harsh double buzz means your balance is too low, and everyone behind you now knows it. That beep vocabulary is the fastest way to catch a problem before the doors close.
Taxi: Nearly every Seoul taxi has a T-money reader mounted by the passenger seat. Tap it at the end of the ride instead of hunting for cash. It works for regular and deluxe cabs alike.
Convenience stores: The same card pays for your triangle kimbap and your water. It is not a transit-only card, and using the leftover balance on snacks is often the cleanest way to zero it out before you fly home.
Transfers: the part that saves real money
This is where T-money quietly pays for itself. Transfer between subway lines, from subway to bus, or from bus to bus, and the connection is free as long as you tap out and tap in within 30 minutes (the window stretches to 60 minutes late at night). You get up to four free transfers on a single journey. You still pay any distance difference, but the second base fare is waived.
The whole system hinges on tapping out. A tourist who taps in but never taps out is treated as though every leg is a brand-new full-fare trip. Locals do this on autopilot; visitors have to build the habit on day one.
Getting from the airport
From Incheon, the AREX airport railroad has two trains. The all-stop commuter train to Seoul Station costs about ₩5,000, takes roughly an hour, and — this is the point — accepts your T-money card at the gate like any normal subway ride. The nonstop express is faster at around 43 minutes but runs ₩13,000, needs a separate reserved-seat ticket, and does not use your T-money balance.
For most travelers the all-stop train is the right call. You tap the card you just bought, you save around ₩8,000, and you arrive fifteen minutes later than you would have. That is a good trade on your first jet-lagged afternoon.
Refunds before you leave
You can cash out your remaining balance, and the rules depend on how much is left.
- Up to ₩20,000: Any major convenience store handles it on the spot. Hand over the card, say “refund,” and they give you the balance in cash minus a ₩500 fee. The fee comes out of your balance automatically.
- ₩20,000 to ₩50,000: Convenience stores will turn you away. Go to a T-money service desk inside a major subway station — the customer center near the gates — and they process it there.
- Over ₩50,000: You need the T-money headquarters near Seoul Station. Almost no tourist ever hits this, because it means you loaded far more than a trip needs.
The practical move is to run your balance low near the end of the trip — buy snacks, pay for the airport train — so whatever is left fits the convenience-store limit and the ₩500 fee is the only thing you lose.
T-money vs. the alternatives
T-money is the default for a reason, but three other options come up constantly. Here is the honest comparison for 2026.
| Card | Upfront cost | Works on | Refund | Best for |
|---|---|---|---|---|
| T-money | ₩2,500–4,000 (card, non-refundable) | Subway, bus, taxi, stores — nationwide | Balance back minus ₩500 at convenience stores (up to ₩20,000) | Almost every visitor |
| WOWPASS | ₩5,000 fee (non-refundable) | Card payments everywhere + T-money transit (topped up separately) | Cash balance refundable at WOWPASS machines in the city | Travelers who want one card to exchange cash, shop, and ride |
| Contactless EMV (foreign Visa/Mastercard) | ₩0 | Not on subway or bus readers yet in 2026 — kiosks and mobile top-up only | N/A | Nobody yet; direct tapping is a 2027 rollout |
| Climate Card | ₩3,000 card + pass | Unlimited Seoul subway and bus | Card cost and unused days non-refundable | Heavy Seoul-only days |
A few notes on that table. WOWPASS bundles currency exchange, a prepaid debit card, and T-money into one piece of plastic, which is genuinely convenient — but the ₩5,000 membership fee never comes back, and its transit balance is a separate top-up from its spending balance, which confuses people. Contactless open-loop payment — tapping your own foreign credit card straight on the gate — is the future everyone asks about, and it is not here yet: Seoul is fitting EMV modules to bus terminals through 2026 and replacing subway readers on Lines 1–8 in 2027, so plan around T-money, not around your Visa. The Climate Card gives unlimited Seoul rides on short-term tourist passes priced from about ₩5,000 for one day to ₩20,000 for seven, which only beats T-money if you are cramming five or more rides into a Seoul-only day. Ride less than that, or leave the city, and pay-as-you-go T-money wins.
The Namane card deserves a mention too: it is a customizable prepaid card foreigners can top up by app or kiosk, transit included, popular mostly for the K-pop photo you can print on the front.
Common mistakes to avoid
- Assuming every top-up point takes cards. Convenience-store transit top-ups are cash only, and so are the older blue station kiosks. Only the newer touchscreen station machines take a foreign card, so carry a few ₩10,000 notes anyway.
- Forgetting to tap out. No exit tap means no free transfer and a distance penalty on your next ride. On the bus especially, tap again when you step off.
- Overloading before you leave. Money above ₩20,000 turns a two-minute convenience-store refund into a trip to a service desk. Load in small amounts near the end.
- Buying the express airport train by reflex. The ₩13,000 express is a separate ticket; your T-money card rides the all-stop train for well under half of that.
- Assuming your home credit card taps the gate. It does not, not in 2026. Get the card or use a phone wallet.
Get the card in the first hour, load a little cash, and build the tap-in-tap-out habit before you overthink it. After two rides it becomes muscle memory, and Seoul opens up to a single flick of the wrist. For more on getting around and settling in, browse the rest of the guides.
