T-Money Card in Korea: What It Is, Where to Buy It & How to Use It (2026)
You just landed at Incheon. Everyone around you is breezing through the subway turnstiles, tapping a small card and walking straight through. You're fumbling for cash, wondering if you need a ticket, and the line behind you is growing. That small card is a T-Money card (also written T Money card in many searches) — and yes, you need one.
Narae explains what a T-Money card is, where to buy one at Incheon Airport, what it costs, and how to get your money back before you fly home.
Last verified: 29 July 2026. Every fare below was checked directly against the Seoul Metropolitan Government's official fare tables — subway table dated 28 June 2025, bus table dated 12 August 2023, both published at news.seoul.go.kr. Figures we could not confirm at the primary source are labelled *widely reported* so you know which numbers to double-check.
What Is a T-Money Card?
South Korea's reloadable transit card — think London's Oyster or Tokyo's Suica. You load cash onto it, tap at subway turnstiles and bus readers, and can even use it to pay for snacks at convenience stores.
It works across Seoul's entire subway and bus network and covers most major Korean cities: Busan, Incheon, Daejeon, Daegu, and more. One card, one country.
The card itself is credit-card-sized plastic. Basic versions come in plain designs; Kakao Friends character editions and other designs are available at a slightly higher price.
Do You Actually Need One?
Short answer: yes — even for a two-day visit.
| Payment method | Subway fare | Transfer discount |
|---|---|---|
| T-Money card | ₩1,550 | ✅ Yes |
| Single-use paper ticket | ₩1,650 | ❌ No |
| Foreign credit/debit card | Varies by line | Varies |
| Mobile T-Money | ₩1,550 | ✅ Yes |
T-Money cards are sold at convenience stores and subway stations. Single-use tickets come from station vending machines only. Mobile T-Money runs on Galaxy phones and select iPhone models, but the wallet app needs a Korean payment setup — not usually an option for short-stay visitors.
Official subway fares by rider type
| Rider | Transit card | Single-use |
|---|---|---|
| Adult | ₩1,550 | ₩1,650 |
| Youth (13–18) | ₩900 | ₩1,650 |
| Child (6–12) | ₩550 | ₩550 |

The transfer discount is the biggest reason to get one. Seoul charges by distance, not by ride: the base fare covers the first 10 km, then ₩100 is added every 5 km beyond that (every 8 km past the 50 km mark). Switch from the subway to a bus on a transit card and you keep paying that single distance-based fare instead of a second base fare — a transfer time window applies, commonly cited as 30 minutes. Over a few days of sightseeing, that adds up. Foreign credit cards work on some subway lines but are unreliable on buses and taxis. A T-Money card covers everything in one tap.
Where to Buy a T-Money Card in Korea
At Incheon Airport — the easiest first stop
Both Terminal 1 and Terminal 2 have GS25 and CU convenience stores on the arrivals level. Before you reach the taxi stand or Airport Railroad platforms, you'll walk past the convenience store area — grab one there before you even leave the building. Confirmed available at both terminals (airport.kr).
At any convenience store
GS25, CU, 7-Eleven, and emart24 all sell them at the counter. Hand over cash, say *T-Money card juseyo* (티머니 카드 주세요), and the cashier handles the rest. You can top it up at the same counter in the same visit.
At subway station machines
Most Seoul subway stations have top-up and card-issuance machines near the turnstiles. English menus are available. Slightly slower than the convenience store counter if there's a queue.
How Much Does It Cost?
| Item | Price |
|---|---|
| Basic card (plain design) | widely reported as ₩2,500 |
| Design / character card (Kakao Friends, etc.) | ₩3,000 – ₩5,000 |
| Minimum top-up | ₩1,000 |
| Maximum balance | widely reported as ₩500,000 |
*Card price and balance limit are widely reported across multiple sources including t-money.co.kr and english.visitkorea.or.kr, but we could not confirm them at the primary source — treat these two as approximate. Checked 29 July
- The card cost itself is non-refundable.*
The card cost and the balance are separate — you pay for the card, then load however much you plan to spend. For a 3-day trip, loading ₩30,000 – ₩50,000 at the start covers most transit needs. Add more if you plan to use it at convenience stores too.
Where Can You Use It?
| Category | Details |
|---|---|
| Subway | All Seoul Metro lines 1–9, Gyeongui-Jungang Line, Airport Railroad (AREX local stops), most intercity lines across Korea |
| City bus | Every route type in Seoul — see the fare table below |
| Taxi | Most regular taxis — tap the card reader at the meter panel |
| Convenience stores | GS25, CU, 7-Eleven, emart24 — food, drinks, everyday purchases |
| Some retail | Selected coffee shops and vending machines; look for the T-Money logo |
Official bus fares by route type (transit card)
| Route type | Fare | Before 6:30 a.m. |
|---|---|---|
| Trunk & branch | ₩1,500 | ₩1,200 |
| Circular | ₩1,400 | ₩1,120 |
| Village | ₩1,200 | ₩960 |
| Express | ₩3,000 | ₩2,400 |
| Night (N-routes) | ₩2,500 | — |
Night buses are the N-numbered routes that run roughly midnight to 5 a.m., after the subway stops. They're the reason a late arrival at Incheon doesn't have to mean a taxi.

How to Top Up
Three ways:
-
Convenience store counter — Hand the card and cash to the cashier. Works everywhere in Korea. The most reliable option.
-
Subway station machine — Insert card, insert cash, done. English menu available. Works 24/7 at most stations.
-
Mobile app — Possible with a Korean bank account or compatible setup. Not the usual tourist route.
You can't top up with a foreign credit card in person. Bring Korean won cash for top-ups.
How to Get a Refund
Any remaining balance can be refunded in cash when you leave Korea.
| Refund location | Balance limit | Fee |
|---|---|---|
| Convenience store (GS25, CU, 7-Eleven) | Varies by location — sources report ₩30,000 – ₩50,000 | widely reported as ₩500 |
| T-Money Town (Seoul Station, underground concourse) | Any amount | widely reported as ₩500 |
*Refund fee is widely reported as ₩500, including via t-money.co.kr, but we could not confirm it at the primary source. Checked 29 July 2026. The card cost itself is non-refundable.*
The ₩500 fee applies regardless of how much is left. If ₩3,000 remains, you get ₩2,500 back. Easiest move: spend the balance down at a convenience store the night before you leave, then refund whatever small amount is left.
FAQ
Is the T-Money card worth it for a short trip?
Yes, even for two days. The ₩100 per-ride saving on subway fares and the distance-based transfer discount both kick in from the very first tap. (Bus fares are the same whether you pay by card or cash, so the ₩100 gap applies to the subway only.) The card costs around ₩2,500 and you can refund most of any remaining balance when you leave.
Can I use a T-Money card at convenience stores?
Yes. GS25, CU, 7-Eleven, and emart24 all accept it as a payment method — it works like a prepaid card. The purchase amount is deducted from your balance. Look for the T-Money logo at the register.
Can I get a refund on my T-Money card balance?
Yes. Bring it to any GS25 or CU for balances roughly under ₩30,000 – ₩50,000 (the limit varies by location). A ₩500 handling fee is deducted. Larger balances need to be refunded at T-Money Town inside Seoul Station.
Do I need a T-Money card if I already have a credit card?
Foreign credit cards work on some Seoul subway lines but are unreliable on buses, village buses, and taxis. You'll also miss the transfer discount and the early-bird discount (see Tips below). For first-time visitors, it's the cleaner option.
Where exactly can I buy one at Incheon Airport?
Both Terminal 1 and Terminal 2 have GS25 and CU stores on the arrivals level. You'll pass them before you reach the taxi stands or the Airport Railroad gates — that's the easiest spot. No separate vending machine needed.
Narae's Quick Tips
A few things I've learned from years of using this card:
-
Load ₩10,000 at the airport right away. The Airport Railroad all-stop train to Seoul Station runs ₩4,750 from Terminal 1 and ₩5,350 from Terminal 2 — you don't want to be sorting out a top-up machine with luggage in hand. One thing to know before you tap: the **Express train is a separate ₩13,000 ticket and does not accept T-Money.** Take the all-stop train if you're paying by card.
-
Early-bird saves 20%. If you tap through a subway turnstile before 6:30 a.m. for the first time that day, the base fare drops automatically: subway ₩1,240, village bus ₩960, express bus ₩2,400. Cash and single-use tickets are excluded — transit card only. Worth knowing for early flights or early morning market runs.
-
Tap out as well as in. On buses especially, people forget the exit tap. Your card still works next time, but the system may auto-correct by charging extra on the following journey.
-
Keep it in an outer pocket. Seoul's turnstiles are fast. Having it buried in your bag slows everyone down, including you.
-
Spend it down before your last day. The ₩500 refund fee isn't worth it on a small balance. Spend ₩3,000 at a GS25 on your last evening, then refund the rest.
-
At Incheon, the convenience store beats the vending machine. The counter is almost always faster than the T-Money kiosks during peak arrivals.
