Climate Card vs. WOWPASS vs. T-money: Which Seoul Transit Card Should You Buy in 2026?

Last updated: November 11, 2026. Prices, coverage and purchase rules were checked against the Seoul Metropolitan Government’s official Climate Card page, Seoul Metro’s ticket-machine notices, and WOWPASS’s own service and fee guide.

You land at Incheon, clear immigration, and before you find the exit you are standing in front of a machine that wants you to decide the next seven days of your trip. Three cards are on offer and each is sold as the obvious choice: T-money, the card every guide tells you to buy; WOWPASS, the one the yellow kiosk in arrivals is pushing; and the Climate Card, which promises unlimited rides for the price of a sandwich.

They are not really competitors. They solve three different problems, and in 2026 the rules around all three changed in ways most guides still have not caught up with. Here is the short answer, the exact numbers, and the airport trap that catches thousands of visitors every week.

What changed in 2026 (and why older guides are wrong)

1. The 30-day Climate Card is gone — the tourist passes stayed

Seoul stopped selling and recharging the 30-day Climate Card on August 31, 2026; the commuter product was folded into the national K-Pass scheme and returned as the Climate Pass on September 1. What survived, unchanged in price, is the part visitors use: the 1-, 2-, 3-, 5- and 7-day short-term passes, ₩5,000 to ₩20,000. If a blog tells you to buy a monthly Climate Card, it is describing a product that no longer exists.

2. From October 1, 2026, the pass covers Seoul only

The short-term pass used to stretch into a few Gyeonggi cities. Since October 1, 2026 it works on subways inside Seoul and Seoul-licensed buses, and that is it. Gimpo, Goyang, Gwacheon, Guri, Seongnam, Hanam and Namyangju are out — which quietly rules out Seoul Grand Park Station on Line 4, still listed in plenty of itineraries for the zoo and the art museum.

3. The new ticket machines finally take foreign cards

Since March 17, 2026, the 440 new machines in 273 stations on Lines 1–8 accept overseas-issued Visa, Mastercard, JCB and UnionPay cards — American Express was added on October 1, 2026 — plus Kakao Pay and Naver Pay. Two limits matter: the machines sell only single tickets and Climate Card short-term passes, never an ordinary T-money top-up, and a service fee of about 3.7% is added to every overseas-card purchase.

What did not change: you still cannot tap your own contactless bank card at a Seoul gate. T-money signed agreements with the five big card networks in September 2026, but open payment starts with Seoul city buses in 2027 and subway gates target the same year. Until then everyone needs a T-money card, a Climate Card or a paper ticket. Getting through the gate is only half of it, though — our guide to navigating Seoul without Google Maps covers the other half.

Card 1: T-money — the boring correct answer

T-money is Korea’s original rechargeable transit card and still the safest purchase a visitor can make. You pay per journey: ₩1,550 for a subway ride up to 10 km, plus ₩100 for every further 5 km, and ₩1,500 for a city bus. A bus-to-subway transfer within 30 minutes counts as one journey, which is why a day that feels like six rides is usually three fares.

What it costs and where to buy it

A plain card is about ₩3,000 (designer cards ₩2,500–5,000). Buy one at any convenience store — CU, GS25, 7-Eleven, emart24 — including the branches inside Incheon Airport arrivals, or from a station machine. No passport, no registration, thirty seconds at the counter.

Topping up is still cash-only

This is the most complained-about fact in every Korea travel forum, and it is still true in November 2026: an ordinary T-money card is recharged with won cash only, at convenience-store counters or station machines. The new foreign-card machines do not do it. Carry ₩30,000–50,000 as your transit float, or use the phone workaround below.

Where it works

Everywhere. Subways and city buses in Seoul, Busan, Daegu, Gwangju and Daejeon; most taxis showing the T-money logo; small purchases at convenience stores and many kiosks. If your trip includes a KTX run to Busan or a few days in Gyeongju, T-money is the only one of the three that follows you without extra steps. (The KTX ticket itself is always separate — no transit card pays for a high-speed seat.)

Getting your money back

Leftover balance is refundable for a ₩500 fee: under ₩20,000 at GS25 or 7-Eleven, under ₩30,000 at CU or emart24, larger amounts at subway service desks or T-money Town at Seoul Station. Do it before you reach the airport, not at the gate.

The phone version, if you have the right card

On an iPhone (XS or later, iOS 17.2+), the Mobile T-money app has a Foreigner button that skips Korean sign-up: issue a card, add it to Apple Wallet, top up with a Mastercard, American Express, UnionPay or JCB — not Visa, which the app has never listed. Foreign-card top-ups carry a fee of roughly 4.5%, and top-ups inside the Wallet app still need a Korean-issued card. On Android, the KOREA TOUR CARD app accepts all five brands including Visa at about 3.2%. Turn on Express Mode so you tap without unlocking.

Card 2: the Climate Card short-term pass — unlimited, but only inside Seoul

The Climate Card is not a payment card; it is a flat-rate pass. Pay once and ride as much as you like on Seoul’s subway and Seoul-licensed buses for the period you bought. For a sightseeing trip built around palaces, markets, cafés and shopping districts, it is usually the cheapest option in this article.

Prices

• 1 day — ₩5,000 · 2 days — ₩8,000 · 3 days — ₩10,000
• 5 days — ₩15,000 · 7 days — ₩20,000
• Plastic card — ₩3,000, bought once (a 7-day youth pass at ₩13,000 needs verification most visitors cannot complete)

The rule that ruins arrival day

You cannot board at Incheon Airport with a Climate Card. The official rule lets you exit at Terminal 1 or Terminal 2 on the Airport Railroad if you boarded inside the coverage area — useful on your way home — but boarding there is not permitted. Since the pass starts on the day you load it and cannot be pre-loaded for a later date, there is no sensible way to use it for the ride into the city anyway. Pay that first leg with T-money or a single-journey ticket, and start the pass the next morning.

Where the pass stops working

• Subway stations outside Seoul — including Gimpo, Goyang, Gwacheon, Guri, Seongnam, Hanam and Namyangju since October 1, 2026. Board in Seoul and exit outside it and staff collect the full fare from where you boarded.
• Sinbundang Line and GTX — the fast lines toward Gangnam are excluded.
• Express, intercity and airport limousine buses, and buses licensed outside Seoul.
• Taxis, Ttareungi bikes and the Hangang Bus — none are included in short-term passes, despite older guides.

Seoul-licensed buses are the generous exception: a blue or green city bus, night bus or circular bus stays covered even when it crosses the city line.

How many rides before it pays off

At ₩1,550 a subway journey, the 1-day pass breaks even at four journeys — a punishing day. Longer passes are far more forgiving: the 3-day needs about seven journeys in total, the 5-day ten, the 7-day thirteen. Add the ₩3,000 card and the 3-day wants roughly ten, which is what an ordinary three-day Seoul trip already looks like. A two-ride-a-day trip never earns it back; a trip hopping between Hongdae, Jongno, Seongsu and Gangnam does.

How to buy and load it

Physical cards are sold and loaded at the new machines on Lines 1–8, or at convenience stores near stations on Line 9, the Ui-Sinseol Line and the Sillim Line. Pay with cash, a Korean card, or a foreign card with the 3.7% fee. Android 12+ users can hold the pass on their phone; iPhone users get the plastic card. Loading counts as day one and runs from the first train (around 4 a.m.) to the last train of the final day, so buy it in the morning.

Card 3: WOWPASS — exchange, payments and transit in one

WOWPASS exists for one specific frustration: your foreign card getting declined, or your cash sitting in the wrong currency. It is a prepaid card you load by feeding banknotes into a kiosk, and it has a T-money chip inside.

• Card cost: ₩6,000 at a kiosk since March 4, 2026, or ₩5,500 with an app voucher; replacement ₩4,000.
• Exchange: cash in 16 currencies — USD, EUR, JPY, GBP, AUD, CAD, SGD and more — at 450-plus kiosks, including Incheon Airport arrivals, many hotels and subway stations. Notes only, no commission.
• Fees that do apply: cash top-up at a kiosk is free; credit-card top-up in the app costs about 4%; cash withdrawal is ₩1,000 per withdrawal, capped at ₩100,000.
• Limits: maximum balance ₩1,000,000; the card works for six years, so it can wait for your next trip.

The two-balance catch

Money you exchange goes into the payment balance, which works at shops, restaurants and Korean sites that reject foreign cards. The T-money balance is a separate pocket and starts empty: fill it with cash at a store or station machine, or in the app by tapping the card to your phone. Load the transit side before you queue at a gate, and know that a lost card means the transit balance is gone even if the payment balance is protected. Kiosks in the AREX area of Incheon Airport take Korean won cash only for top-ups and cannot pay out withdrawals, so cash out in the city.

Head-to-head: the five things that actually decide it

	T-money	Climate Card (short-term)	WOWPASS
Issue fee	₩2,500–5,000	₩3,000 + pass (₩5,000–20,000)	₩6,000 (₩5,500 app voucher)
What it saves / covers	Pay per ride; transfer discounts; nationwide	Unlimited subway + Seoul buses inside Seoul	No fare discount; saves card fees and bad exchange rates
Convenience-store payment	Yes (small amounts)	No — transit only	Yes, its main strength
How you top up	Won cash at stores/machines; foreign card via phone app	Cash, Korean card, or foreign card (3.7% fee) at new machines	Foreign cash at kiosks (free); credit card in app (4%)
Incheon Airport Railroad	✅ both directions	⚠️ exit only, no boarding	✅ both directions (load the transit side)

Do the math for your trip

Three nights in Seoul, four journeys a day (12 total). Climate Card 3-day pass: ₩10,000 + ₩3,000 card = ₩13,000. T-money: 12 × ₩1,550 = ₩18,600, plus a card and an airport fare you need anyway. The pass wins by about ₩5,000, and by more past 10 km.

Seven nights, two leisurely journeys a day. Fourteen fares is roughly ₩21,700 on T-money; the 7-day pass costs ₩20,000 plus ₩3,000 for the card, so T-money is ahead unless your days are busier than your plan.

Seoul plus Busan. A 5-day Seoul pass (₩18,000 with card) is excellent for the Seoul half, but does nothing for the KTX, the Busan subway or taxis — the itinerary that justifies two cards.

The five traps that cost travelers money

1. Using the Climate Card at Incheon Airport. You cannot board there. Budget that leg separately, every time.
2. Loading the pass at 11 p.m. The day you load it is day one — charge it the morning you start sightseeing.
3. Assuming a day trip is covered. Suwon, Incheon’s Chinatown, Seoul Grand Park and the Sinbundang Line are outside the pass.
4. Expecting WOWPASS exchange money to open a gate. The transit balance is separate and empty until you load it.
5. Carrying no cash. T-money top-ups and most store counters still want won.

What to do in the arrivals hall, in order

1. Get cash. An ATM in arrivals — you need won today, not next week.
2. Buy T-money at a convenience store and load ₩10,000–20,000 for the airport train and your first evening.
3. Optional: pick up a WOWPASS at a yellow kiosk in arrivals — passport required, five minutes.
4. Ride into the city on the all-stop AREX with T-money, or buy an Express ticket separately.
5. Next morning, at a Lines 1–8 machine, buy the Climate Card pass that matches the rest of your stay and start it that day.

One line per traveler type

• 1–3 nights, city-center and walking-heavy: T-money only; skip the pass.
• 3–7 nights, Seoul-only, three or more journeys a day: Climate Card pass from your first full day, T-money for the airport.
• Cross-country trip (Busan, Gyeongju, Jeju ferries): T-money as the backbone, plus a Climate Card if you are based in Seoul for several days.
• Card-first traveler who avoids cash: WOWPASS, with the transit side loaded before your first gate.
• iPhone user with only a Visa: physical T-money plus a Climate Card from the station machine — Visa works at the machines even though the T-money app will not take it.

Quick answers

Can two people share one card? A Climate Card pass is one per person. T-money can be handed back, but you lose the transfer discount.

Does the Climate Card work at Gimpo Airport? Yes — Gimpo Airport Station is inside Seoul, on Lines 5 and 9 and the airport railway.

Can I put the Climate Card on my iPhone? No. The mobile pass is Android 12+ only; iPhone users carry the plastic card.

Can I tap my own contactless card at a Seoul gate? Not yet — foreign cards in Apple Wallet are not read either. Open bank-card tapping begins with city buses in 2027.

What about Kakao Pay or Naver Pay? Both work at the new machines, but need a Korean phone number and bank account, so they are not realistic for a short visit.

The bottom line

Buy T-money the moment you land: it is cheap, it carries you in from the airport, and it never stops working for the rest of the trip. Then, on your first full day in Seoul, decide whether your itinerary is busy enough for a Climate Card pass — three or more crossings a day, and it pays; a slow walk around Myeongdong and Jongno, and it does not. And if your foreign card is the worry, WOWPASS buys peace of mind for ₩6,000, as long as you load the transit side separately.

Whichever card ends up in your pocket, the next problem is knowing where you are going with it. Start with How to Navigate Seoul Without Google Maps, then come back to this page when you are standing at the machine with ₩10,000 in your hand.
