T-money Card Guide 2026: Where to Buy, How to Use & Refund
⚡ Quick Answer: A T-money card is Korea's rechargeable transit card. Buy one at any convenience store or airport for ₩2,500–₩4,000, load ₩30,000–₩50,000 in cash for a 3–4 day trip, and tap on and off every subway and bus ride. Before flying home, refund your leftover balance at a convenience store (₩500 fee — the card price itself is not refundable).
If you ride the subway or bus in Korea even twice, you need a T-money card. It's the rechargeable smart card that nearly every Korean uses daily — one tap gets you through subway gates, onto buses, into taxis, and it even pays for snacks at convenience stores. This 2026 guide covers exactly where to buy a T-money card, how much to load, how the transfer discount works, and how to get your leftover money back before you leave Korea. We'll also cover two big 2026 updates: iPhone support for Mobile T-money and new subway kiosks that finally accept foreign credit cards.
What Is a T-money Card? (And Why Every Tourist Needs One)
T-money (티머니) is Korea's national transit card — the equivalent of London's Oyster, Tokyo's Suica, or Hong Kong's Octopus. It's a contactless prepaid card: you load money onto it, then tap it on card readers to pay.
Here's what one card covers:
- Subway — Seoul, Busan, Daegu, Daejeon, Gwangju, Incheon
- City buses — nationwide, including Jeju
- Taxis — most taxis in major cities
- Convenience stores — CU, GS25, 7-Eleven, Emart24
- Extras — vending machines, coin lockers, some cafes and bakeries
Two more reasons it beats paying cash or buying single-ride tickets:
- You save ₩100 per ride compared to cash or single-journey tickets.
- Free transfers between bus and subway within 30 minutes (more on this below) — with single tickets, you pay full fare every time.
💡 Good to know: T-money cards never expire. If you visited Korea years ago and still have one in a drawer, it will work the moment you tap it — balance included. Keep yours for your next trip.
Where to Buy a T-money Card in 2026
Buying one takes about 60 seconds. Here are your options, compared:
| Where | Card Price | Payment | Best For |
|---|---|---|---|
| Convenience stores (CU, GS25, 7-Eleven, Emart24) | ₩2,500–₩4,000 | Cash or card (for the card itself) | Everyone — they're everywhere, including inside Incheon Airport arrivals |
| Subway station vending machines | ₩2,500–₩3,000 | Cash | Arriving by AREX and heading straight to the subway |
| Tmoney Travel Card booths (airport limousine ticket counters) | ~₩4,000 | Cash | Tourists who want attraction discounts (see below) |
| Character edition cards (Kakao Friends, Line Friends, BTS) | ₩4,000–₩10,000 | Cash or card | Souvenir hunters — same function, cuter design |
The simplest move: after clearing arrivals at Incheon Airport, walk into the CU or GS25 in the arrivals hall, point at the T-money rack near the register, and say "T-money." Pay for the card, then hand over cash to load it. Done — you can tap straight onto the AREX train to Seoul.
⚠️ 2026 update — Korea Tour Card is discontinued. Older blogs recommend the "Korea Tour Card" for tourists. It no longer exists. Its replacement is the Tmoney Travel Card — a tourist edition with traditional Korean designs and discounts at select attractions and shops. It works exactly like a regular T-money, so only bother if the discounts match your itinerary.
What About Mobile T-money on Your Phone?
This changed in 2026. As of March 2026, the Mobile T-money app supports foreign visitors on iPhone — you add a T-money card to Apple Wallet and tap your phone at the gate. Top-ups work with foreign Mastercard, American Express, and UnionPay (Visa support is expected later).
The catch: foreign card top-ups carry a ~3.7% service fee. Loading ₩50,000 costs you about ₩51,850. For a short trip that's minor; for a longer stay, the plastic card + cash is still cheaper.
How to Charge (Top Up) Your T-money Card
Your card comes empty — you need to load money before the first tap. Minimum load is ₩1,000; maximum is ₩500,000, but for refund reasons (explained below) never load more than ₩50,000 at a time.
| Method | Payment Accepted | Notes |
|---|---|---|
| Convenience store counter | Korean cash (₩) only | Hand over card + cash, say "chungjeon" (충전). Takes 5 seconds |
| Subway station kiosks | Cash + foreign credit cards (NEW 2026) | English menu available; newly updated Seoul Metro kiosks now accept foreign Visa/Mastercard |
| Mobile T-money app | Foreign Mastercard/Amex/UnionPay | iPhone + Android; ~3.7% fee on foreign cards |
⚠️ Important: Convenience stores cannot load T-money with a foreign credit card — Korean POS terminals only accept cash for transit top-ups. If you're cash-free, use the new subway station kiosks instead.
How Much Should You Load?
Seoul's base subway fare is around ₩1,550 with a T-money card (2026), and buses are similar. A realistic budget:
- 3–4 day Seoul trip: ₩30,000–₩50,000
- 1 week: ₩50,000 total — load ₩30,000 first, top up once mid-trip
- Rule of thumb: keep at least ₩5,000 on the card so you never get stuck at a gate
How to Use It: Tap On, Tap Off (Always)
Using T-money is simple, but there's one rule tourists constantly get wrong: you must tap when you get ON and when you get OFF — on buses too, not just the subway.
📱 Pair it with the right apps: Your T-money card gets you through the gates, but you'll still need directions, subway timing, and taxis. Download our 5 Essential Apps for Korea Travel before you land — Google Maps barely works in Korea.
- Subway: tap at the gate to enter, tap again to exit. Fare is calculated by distance.
- Bus: tap the reader when boarding, tap the reader by the rear door when getting off.
- Taxi: tell the driver "T-money" at the end of the ride and tap the reader.
- Convenience store: hand the card over or tap the reader — works like a prepaid debit card.
The Transfer Discount (Free Transfers Explained)
This is where T-money quietly saves you real money. When you switch between bus ↔ subway (or bus ↔ bus on different routes) within 30 minutes of tapping off, the system treats it as one continuous journey — you pay by total distance instead of a fresh base fare.
- Works up to 4 times per day
- Transfer window extends to 1 hour between 9 PM and 7 AM
- Doesn't apply between buses on the same route number
- Only works if you tapped off your previous ride — this is why the tap-off habit matters
- Each traveler needs their own card — sharing one card kills the transfer discount
💡 Tip: Forgot to tap off a bus? You lose the transfer discount and may be charged a penalty fare based on the full route distance. Make tapping off automatic.
How to Refund Your T-money Balance Before You Leave
Don't fly home with money on your card — tourists throw away thousands of won this way every day. Here's the refund system in 2026:
| Remaining Balance | Where to Refund | Fee |
|---|---|---|
| Under ₩20,000 | Any major convenience store (CU, GS25, 7-Eleven) | ₩500 |
| ₩20,000–₩50,000 | Subway station customer service center (고객센터) — bring your passport | ₩500 |
| Over ₩50,000 | Requires a Korean bank account — not practical for tourists | — |
At the convenience store, just hand the cashier your card and say "hwanbul" (환불) — refund. You'll get your balance back in cash, minus the ₩500 fee.
Three things to know:
- The card purchase price (₩2,500–₩4,000) is never refunded. It's not a deposit — you bought the card. Keep it as a souvenir; it works forever.
- Refund before airport security. There are no refund counters past security at Incheon — use the arrivals-level convenience store before check-in.
- Or just spend it down: use the leftover balance for snacks and drinks at a convenience store, or your AREX ride to the airport.
T-money vs Climate Card vs WOWPASS: Which Should You Get?
T-money isn't the only card tourists hear about in 2026. Quick comparison:
| T-money | Climate Card (Tourist Pass) | WOWPASS | |
|---|---|---|---|
| What it is | Pay-per-ride transit card | Unlimited-ride pass, Seoul only | Prepaid debit card + currency exchange (includes T-money function) |
| Cost | ₩2,500–₩4,000 + what you load | ~₩5,000/day to ₩20,000/7 days | Card fee + load foreign currency |
| Coverage | Nationwide | Seoul metro area only | Nationwide (transit via built-in T-money) |
| Best for | Most tourists; any multi-city trip | Seoul-only trips with 4+ rides per day | Travelers who also want a cashless payment card |
Our take: for a first visit, just get a regular T-money. It's the cheapest, works everywhere in the country, and there's zero learning curve. Consider the Climate Card 7-day pass (₩20,000) only if you're staying inside Seoul and genuinely riding transit 4+ times daily.

Frequently Asked Questions
Can I buy a T-money card with a foreign credit card?
Yes — the card itself can usually be purchased with a foreign credit card at convenience stores. However, loading money onto it at convenience stores requires Korean cash. To top up with a foreign card, use the new 2026 subway station kiosks or the Mobile T-money app (Mastercard/Amex/UnionPay, ~3.7% fee).
Does one T-money card work outside Seoul?
Yes. The same card works on subways and buses in Busan, Daegu, Daejeon, Gwangju, Incheon, and most cities nationwide, plus Jeju city buses. You do not need a new card for each city.
Is the T-money card price refundable?
No. The ₩2,500–₩4,000 you pay for the card is a purchase, not a deposit. Only the balance you load on top is refundable (minus a ₩500 service fee). The card never expires, so keep it for future trips.
How do I refund my T-money balance at the airport?
Go to a convenience store on the arrivals level at Incheon before passing security — there are no refund points inside the departure gates. Balances under ₩20,000 are refunded in cash at CU, GS25, or 7-Eleven with a ₩500 fee. For ₩20,000–₩50,000, use a subway station customer service center with your passport.
Can I use Apple Pay or my iPhone as a T-money card?
Yes, as of March 2026. Download the Mobile T-money app, select the foreigner option, and add a T-money card to Apple Wallet. You can top up with a foreign Mastercard, American Express, or UnionPay card (a ~3.7% service fee applies; Visa support is expected to follow).
Do children pay the same fare with T-money?
Standard tourist T-money cards charge the adult fare by default. Youth (13–18) and child (6–12) discount fares require registering the card as a youth/child card, which is possible at convenience stores with the child's passport.
