South Korea runs one of the cleanest, fastest public transit systems in the world. Get a transit card as soon as you land. It works on subways, city buses and many taxis in Seoul and Busan.
But choosing between Korea transport cards can feel confusing for first-timers. The classic T-money card, the tourist-focused WOWPASS, and Seoul's newer Climate Card each solve different travel needs.
It depends on your trip. Some cards work nationwide from Seoul down to Busan and Jeju Island.
Others offer flat-rate unlimited rides only within Seoul city limits. Before flying into Incheon International Airport, check the UK Foreign Travel Advice for South Korea and Canadian Travel Updates for entry rules and customs regulations.
Korea transport cards compared
The table below summarizes card purchase prices, geographic transit validity, reload options, and retail payment support as of October 2026.
| Card type | Card issuance fee | Geographic transit range | Reload currency accepted |
|---|---|---|---|
| Classic T-money | 3,000–5,000 KRW | Nationwide across Korea | Korean Won cash only |
| WOWPASS | 5,000 KRW | Nationwide (via T-money) | Foreign cash + KRW cash |
| Climate Card | 3,000 KRW (physical) | Seoul city transit only | Korean Won cash only |
The classic T-money card
The T-money card is the long-standing transit staple across South Korea. You can buy a physical card at almost any convenience store, such as GS25, CU, 7-Eleven or Emart24, or from subway station machines for 3,000 to 5,000 KRW.
Once you load your card, you can tap it across the entire Seoul metro and city buses, as well as in Busan, Daegu, Gwangju and on Jeju Island buses. You can also pay for registered taxi rides and buy snacks at convenience stores.
The main catch with T-money is that you can't reload it with a foreign credit card. Station kiosks and convenience store clerks only take Korean Won cash for reloads. You'll need to withdraw cash from a local ATM to keep your card topped up.
You'll also get an automatic transfer discount. When you transfer between a subway line and a bus within 30 minutes, your second ride is discounted or free. Just remember to tap your card against the sensor when you get off, not just when you board.
WOWPASS: tourist debit card and transit combo
The WOWPASS is a prepaid chip-and-PIN card created specifically for international visitors. You get one from bright orange self-service kiosks at Incheon Airport, Gimpo Airport, and major subway stations. It combines two separate balances on one piece of plastic.
Its primary balance works like a local debit card. You feed your home currency (like USD, EUR, GBP, or JPY) into the kiosk.
The machine exchanges your money at solid rates and loads Korean Won onto the card. You can then tap or insert it at shops, cafes, and restaurants across the country that accept local cards.
The second balance is a built-in T-money transit chip. Here's what confuses many travelers: the two balances don't share money.
Loading cash into the WOWPASS kiosk doesn't fund your subway rides. You still have to put physical Korean Won cash into a subway machine to top up the transit chip. Even so, travelers like WOWPASS because its phone app sends instant spending alerts after every purchase.
Seoul Climate Card: unlimited rides for city explorers
Launched by the Seoul city government, the Climate Card offers unlimited transit for a flat daily rate. While it started as a monthly pass for residents, visitors can now buy short-term tourist passes. Options include 1-day (5,000 KRW), 2-day (8,000 KRW), 3-day (10,000 KRW), 5-day (15,000 KRW), and 7-day (20,000 KRW) passes.
You buy a physical card for 3,000 KRW at subway station customer offices or nearby convenience stores. Then you activate your selected duration at a station machine using Korean Won cash.
During your active days, you get unlimited rides on Seoul Subway lines 1 through 9, the Ui-Sinseol LRT, and Seoul city buses. If you're taking four or five trips a day between palaces, shopping alleys, and night markets, it saves real money.
Keep in mind that the Climate Card has strict geographic boundaries:
- It's Seoul-only. It won't work on the Busan metro, Jeju buses, or intercity trains.
- Excluded routes: It doesn't work on the AREX Express train from Incheon Airport. It's also not valid on the Shinbundang Line or buses running outside Seoul borders.
If you ride past Seoul city limits into Gyeonggi province, station gates won't let you exit until you pay a fare adjustment.
Airport transit: getting from Incheon into Seoul
Your transit choices start right as you walk out of the baggage hall at Incheon International Airport. You have three main rail options to reach central Seoul: the AREX Express Train, the AREX All-Stop commuter train, or regional airport limousine buses.
The AREX Express runs non-stop between Incheon Airport and Seoul Station in 43 minutes. It needs its own reserved ticket.
You can't use a Climate Card or tap T-money at the gate. However, WOWPASS kiosks at Incheon Airport let you buy discounted AREX Express tickets using your card balance.
The AREX All-Stop train takes roughly 59 minutes and operates like an ordinary commuter train. You can tap through the gates using your classic T-money card or the transit balance on your WOWPASS.
Remember that the Climate Card does not cover trips originating from Incheon Airport. Want to use a Climate Card? Ride the AREX All-Stop train into Seoul on a regular T-money card, then activate the Climate Card when you start sightseeing.
Why mobile transit cards don't work for tourists
Many travelers wonder if they can simply add a digital T-money card to Apple Wallet or Google Wallet on their smartphones. While local Korean residents use mobile transit apps daily, foreign tourists generally cannot use these mobile services.
Korean mobile payment systems require authentication through a Korean resident registration number or an alien registration card (ARC), paired with a domestic Korean mobile telecom contract. A travel eSIM won't help here. Korean transit apps need a resident ID check before they'll link a foreign card.
Because of this limitation, international visitors must rely on physical plastic cards. Keep the card in your phone case or on a lanyard. Tapping in gets quick.
Which Korea transport card should you pick?
Picking the right card comes down to your travel plans:
- Pick the Climate Card if you're spending three to seven days mainly in central Seoul. It takes away the guesswork of calculating fares and saves money on busy sightseeing days.
- Pick the WOWPASS if you want an easy way to pay at restaurants and shops without carrying wads of paper cash.
- Pick the classic T-money card if you're traveling outside Seoul to Busan, Gyeongju, or Jeju. It gives you reliable transit coverage across the whole country.

Frequently asked questions
Can I reload a T-money card with a foreign credit card?
No. Station ticket machines and convenience stores in South Korea accept only physical Korean Won cash for T-money reloads. Ensure you withdraw cash from a global ATM before heading to the subway gates.
Does the Climate Card work from Incheon Airport to central Seoul?
The Climate Card does not cover travel from Incheon Airport. It only covers the AREX all-stop train from Gimpo Airport eastward into central Seoul. To travel from Incheon Airport, use a standard T-money card, purchase an AREX Express ticket, or take an airport limousine bus.
Can two people share a single T-money card on the subway?
No. On subways, every passenger must tap their own card at the turnstiles. While some city bus drivers can manually configure a single card for multiple riders, carrying one card per traveler is strongly recommended to prevent delays.
Where can I get a refund for my remaining card balance?
For T-money and WOWPASS transit balances, convenience stores can refund balances under 20,000 KRW with a 500 KRW processing fee. For WOWPASS shopping balances, you can withdraw Korean Won cash directly at any orange WOWPASS kiosk.
