How to Use a T-money Card in Korea: Step-by-Step Guide (2026)
If you're planning a trip to Korea, the T-money card is one of the most useful things you'll buy. One small card lets you tap onto every subway, bus, most taxis, and even pay at convenience stores.
If you're planning a trip to Korea, the T-money card is one of the most useful things you'll buy. One small card lets you tap onto every subway, bus, most taxis, and even pay at convenience stores.
I live in Korea, and I still see visitors at subway stations struggling with single-ride machines while everyone else just taps and walks through. So here's everything you actually need to know in 2026.
⚠️ Prices below were accurate at the time of writing. Always double-check on the official T-money site (t-money.co.kr) before your trip.
Quick Guide: Should You Get One?
Honestly, yes — unless your trip is just one or two subway rides.
Who should get what
- Most travelers — physical T-money card from any convenience store
- Heavy Seoul transit users — consider the Climate Card (unlimited rides)
- iPhone users — new in 2026: load T-money into Apple Wallet with a foreign card
- Galaxy users — only works smoothly with a Korean-region Galaxy phone
Why T-money Is Worth It
Cheaper fares
Seoul subway base fare is ₩1,550 with T-money, vs ₩1,650 for a single-ride ticket (which also requires a ₩500 deposit).
Transfer discount
You get a ₩100 transfer discount when switching between subway and bus within 30 minutes — usable up to four times a day.
Use it almost anywhere
It works at GS25, CU, 7-Eleven, Emart24, taxis, and many vending machines. Basically a low-stakes prepaid card for your whole trip.
Where to Buy
Convenience stores (easiest)
GS25, CU, 7-Eleven, Emart24, or Ministop. Just point at the card display and say "T-money, please." Cards cost ₩2,500–₩5,000 depending on the design.
Incheon Airport
Available at every arrivals-hall convenience store — same price as in the city.
Subway station vending machines
Yellow-and-black Tmoney machines near the gates. English option available.
The card itself is non-refundable — only your loaded balance gets refunded later.
How to Top Up
Top-ups are cash-only in most places if you don't have a Korean bank card.
At a convenience store
Hand the cashier your card and cash, tell them the amount, and they'll load it on the spot.
At a subway station
Use the yellow-and-black Tmoney reload machines near the gates. They have an English option.
Top-up limits
- Increments of ₩1,000
- Up to ₩90,000 per transaction
- Maximum balance: ₩500,000
How much should I load?
| Trip length |
Suggested amount |
| 1 day of sightseeing | ₩7,000–₩10,000 |
| 1 week | ₩30,000–₩40,000 |
| 10 days | ₩40,000–₩50,000 |
Better to under-load and reload than to refund a big balance later (₩500 fee per refund).
How to Use It
Subway
Tap on the round reader when you enter, and tap again when you exit. The exit tap matters — Korea charges by distance.
Buses
Tap as you board. On long-distance buses, tap again when you get off.
Taxis
Look for the T-money sticker on the window. Tap on the dashboard reader when you arrive.
Convenience stores
Say "T-money" at the register and tap.
Apple Wallet T-money for Tourists (New in 2026)
This is the biggest update this year. As of March 19, 2026, foreign visitors can load T-money into Apple Wallet using an overseas card.
Step-by-step setup
- Download the Mobile Tmoney app from the App Store
- Tap the new "Foreigner" button on the login screen
- Add a foreign card — Mastercard, American Express, or UnionPay (Visa not yet supported)
- Top up through the app and add the card to Apple Wallet
- Enable Express Transit to tap without unlocking your phone
Requirements
Works on iPhone 8 and newer. If your card is supported, this is now the smoothest option — no plastic, no cash.
Samsung Wallet (Galaxy Users)
Mobile T-money for Galaxy generally requires a Korean-region Galaxy phone with Korean firmware. Galaxy phones bought overseas usually can't add T-money to Samsung Wallet — so just grab a physical card instead.
How to Refund Your Balance
Before flying home, return your remaining balance for cash.
Refund options
- Up to ₩20,000 — refunded instantly at any convenience store (₩500 service fee deducted)
- Over ₩20,000 — visit a T-money Town service center (main one is at Seoul Station Exit 10)
Pro tip
Most travelers just refund at a convenience store inside Incheon Airport before security. Takes about a minute.
The card itself isn't refundable, but it stays valid for years — keep it for your next visit.
T-money vs Climate Card
| Card |
Best for |
Cost |
| T-money | Most tourists, all of Korea | ₩2,500–5,000 + top-up |
| Climate Card | Heavy Seoul-only users | ₩3,000 card + ₩5,000/day or ₩62,000+/30 days |
The Climate Card only makes sense if you're staying in Seoul and riding transit 4+ times a day. For most trips, plain T-money is cheaper and more flexible.
Tips for Day One
- Always tap on exit in the subway, even if the gate looks open
- Some rural buses are still cash-only — keep ₩1,000 notes as backup
- Each person needs their own card on transit (no sharing)
- Use Naver Map or KakaoMap for accurate fare estimates — Google Maps is limited in Korea
Frequently Asked Questions
Does T-money work outside Seoul?
Yes — Busan, Daegu, Jeju, and almost every Korean city.
Can I top up with a foreign credit card?
Only through the Mobile Tmoney app with Apple Pay (Mastercard, AmEx, UnionPay). Convenience stores and station machines are cash-only.
Does T-money expire?
No. The balance stays valid for years — save it for your next trip.
T-money or Cashbee?
T-money is easier to find and works nationwide. Either is fine.
Does it work on the airport train?
Yes on the all-stop AREX. The Express train requires a separate ticket.
Final Thoughts
T-money is one of the best small purchases on a Korea trip. It saves money on every fare, removes the cash hassle, and works in every city you'd visit.
For 2026, if you have a recent iPhone with Mastercard, AmEx, or UnionPay, the new Apple Wallet T-money setup is the smoothest option. Otherwise, grab a physical card at the first convenience store you see — you'll be tapping into the subway like a local within an hour of landing.
Have a great trip, and I'll keep sharing more practical guides. Thanks for reading.
