Korea Transport & Payment Cards 2026: T-money vs WOWPASS vs Climate Card
You land at Incheon, clear immigration, and hit the first real decision of your trip before you have even seen daylight: which card do you buy? The signs offer T-money, WOWPASS, Korea Tour Card, Discover Seoul Pass, and a short-term Climate Card, and none of them explain how they differ. Most travelers default to whatever the nearest convenience store sells, then discover on day three that they bought the wrong one — a card that cannot be topped up with their Visa, or an unlimited pass that does not cover the airport bus, or a tourist pass whose transit chip arrives empty.
This guide is not a complaint about Korea's payment system. It is a decision tree. Korea runs one of the most reliable closed-loop transit networks in the world; the only real problem for a foreign visitor is that the entry point is unlabeled. Below, we sort the five options by what they actually do, what they actually cost, and which one matches your specific trip — how many days you are staying, which cities you are visiting, and what phone is in your pocket. By the end you should be able to point at exactly one card and buy it.
Taking taxis in Korea? Transit cards are only half the payment picture — taxi apps have their own foreign-card rules, and the wrong setup means a declined payment at 1 a.m. in Hongdae. Our Korea Taxi Guide 2026 (Kakao T, k.ride & Uber Taxi) is a 25-page walkthrough with real screenshots of every setup screen, so your card is registered before you need it.

Start Here: The Decision Tree
Answer these in order. Stop at the first one that matches your trip.
1. Are you staying inside Seoul for 2 to 7 days and using subway and bus as your main transport?
→ Buy a short-term Climate Card (1, 2, 3, 5, or 7 days). With a standard Seoul subway or city bus ride costing ₩1,550 on a card in 2026, the 3-day pass at ₩10,000 breaks even at roughly two rides a day, and the 7-day pass at ₩20,000 breaks even at under two rides a day — add ₩3,000 once for the physical card itself. It also includes Ddareungyi public bicycles. For a Seoul-only itinerary this is almost always the cheapest option, and it is the one most visitors skip.
2. Are you visiting multiple cities — Busan, Jeju, Gyeongju, Gangneung — or staying longer than a week?
→ Buy a T-money card. The Climate Card is Seoul-only. T-money works on transit nationwide and never expires, so it survives your next trip too.
3. Do you want one card that also pays at restaurants, cafés, and shops without touching your home bank card?
→ Buy a WOWPASS. It is a prepaid card issued to foreign passport holders that works at ordinary Korean card terminals, with a T-money transit chip built in. Understand before you buy that it carries two separate balances that must be loaded separately.
4. Are you doing a heavy sightseeing run — palaces, N Seoul Tower, observation decks, museums — in a short window?
→ Consider the Discover Seoul Pass, but evaluate it as an attractions pass, not a transport card. Transit is not free on it.
5. Do you use Alipay, AlipayHK, Touch 'n Go, GCash, PayPay, or Mpay at home?
→ You already have a payment method for shops and taxis via Alipay+. You still need a transit card — the wallet apps do not open subway gates.
The combination most travelers should actually buy: a short-term Climate Card for Seoul transit, plus either cash or your home Visa/Mastercard for retail. Everything else is optimization.
The Five Options, Side by Side
Figures below are current as of mid-2026. Fares and card fees in Korea are revised periodically, so treat the operator's own page as final authority.
| Card | Cost to obtain | How you load it | Where it works | Getting money back |
|---|---|---|---|---|
| T-money | ₩2,500–₩4,000 for the card (non-refundable), balance on top | KRW cash at convenience stores and station machines, in ₩1,000 increments. Mobile T-money app accepts overseas Mastercard, Amex and UnionPay — not Visa — with a card-processing surcharge on top. | Subway and bus nationwide, T-money-branded taxis, convenience stores, coin lockers, some vending machines | Convenience store refunds the balance for a ₩500 fee (chain caps apply, commonly ₩25,000–₩30,000); subway customer service offices handle larger amounts. Card fee is never refunded. |
| WOWPASS | ₩5,000 issuance fee, non-refundable. This is a fee, not a deposit. | Payment balance: foreign banknotes at WOW Exchange kiosks (16+ currencies), or an overseas card in the app. Transit balance: KRW cash at convenience stores or station machines. The two do not share funds automatically. | Most ordinary Korean card terminals — restaurants, cafés, shops, department stores — plus subway and bus via the T-money chip | Withdraw the payment balance as KRW cash at a WOW Exchange kiosk, ₩1,000 fee, ₩100,000 maximum per withdrawal. Transit balance refunds like ordinary T-money. |
| Short-term Climate Card | ₩3,000 for the physical card, then the pass: ₩5,000 (1 day), ₩8,000 (2), ₩10,000 (3), ₩15,000 (5), ₩20,000 (7) | Charge the pass at station ticket machines. Since March 2026, 273 stations on Lines 1–8 accept overseas Visa and Mastercard for this, with a 3.7% processing fee. | Unlimited rides on Seoul-area subway, Seoul-licensed city and village buses, and Ddareungyi bicycles. Excludes the Shinbundang Line, GTX, wide-area (red) buses, airport buses, and subway sections outside the Seoul zone. | Unused days are not refunded. The ₩3,000 card itself is not refundable. |
| Korea Tour Card | ₩4,000 for the card | KRW cash only, same points as T-money | Identical to T-money, plus discounts at 200-plus attractions and shops (N Seoul Tower, Lotte World, COEX Aquarium and similar) | Same as T-money |
| Discover Seoul Pass | Tiered by duration. The lineup is revised periodically — as of 2026 it centres on 72-hour and 120-hour unlimited passes plus cheaper "Pick 3" variants, so check the official site for current pricing. | Attraction entries are prepaid. The T-money chip arrives empty — load it with cash like any T-money card. | Free entry to 70-plus attractions, one AREX airport train ride, one K-Limousine airport bus ride, 24 hours of Ddareungyi. Transit itself is pay-as-you-go. | Unused attraction entries are not refunded. The card keeps working as a plain T-money card afterwards. |
The single most misread line in that table is the Discover Seoul Pass row. It is priced like a transport pass and shelved next to them, but it is an attractions bundle with a blank transit chip attached. Buy it only if you have counted the entry fees you plan to pay and the total clears the pass price.
Where to Buy Each One — and What to Do at Incheon
T-money and Korea Tour Card. Any convenience store — CU, GS25, 7-Eleven, emart24 — including the ones inside both Incheon terminals, plus subway station vending machines. Say "T-money card, please" and hand over cash. Load it at the same counter.
Ignore the artwork on a T-money card. It is sold in hundreds of designs — character editions, city editions, mini cards, keyring fobs — and none of that changes what the card does. A ₩2,500 plain card and a ₩12,000 character card ride the same subway. Check for two things printed on it instead: the T-money mark, and, if you are leaving Seoul or renting a car, the One Card All Pass (전국호환) mark, which is what makes it work on transit nationwide and at expressway toll booths. Novelty shapes are the one exception worth avoiding — keyring and figure-shaped cards can be awkward to tap cleanly on a bus reader.
Short-term Climate Card. Ticket machines inside Lines 1–8 stations, customer safety offices at those stations, convenience stores near subway entrances, and the tourist information centers at Seoul Tourism Plaza, Myeong-dong, and Dongdaemun. Since March 2026 you can complete the whole purchase at a station machine with an overseas Visa or Mastercard, which removes the old requirement to find cash first.
WOWPASS. Here is the detail that catches people out: the Incheon Airport kiosks sit inside the AREX (Airport Railroad) station gates — at the CU stores past the ticket barrier in Terminal 1 and Terminal 2 — not in the arrivals hall. You need an AREX ticket in hand to reach them, they run roughly 06:00–22:50, and they accept KRW cash only; currency exchange and cash withdrawal are not available at the airport machines. Full-service WOW Exchange kiosks that take foreign banknotes are in the city, at 70-plus subway stations, hotels, and tourist areas. If you arrive without Korean won and want a WOWPASS, plan to get it in Seoul rather than at the airport.
Discover Seoul Pass. Pick-up counters at Incheon Terminal 1 (near Gates 2 and 13, and the bookstores on 1F and 3F) and Terminal 2 (3F bookstore), plus the Myeong-dong, Seoul Tourism Plaza, and Dongdaemun tourist information centers.
The efficient arrival sequence: withdraw ₩50,000–₩100,000 in cash from an airport ATM, buy a T-money card at a terminal convenience store and load ₩10,000 onto it, then ride into the city. If your itinerary is Seoul-only, add a short-term Climate Card on day one at any Line 1–8 station and let the T-money card sit as backup for buses outside the Seoul zone. This avoids the two most common arrival mistakes: standing in a WOWPASS queue you cannot use without won, and buying a 72-hour attractions pass before you know your schedule.
One more trap at the AREX platform. The first thing you see downstairs is a bank of Express train ticket machines. The Express is a fine product — nonstop to Seoul Station in about 43 minutes — but it is not the default, and at ₩13,000 bought on the spot it is the most expensive way to make that trip by rail. Pre-booking online brings it down to roughly ₩11,500. The all-stop train runs the same route for roughly ₩4,950, needs no ticket at all, and simply takes the T-money card you bought upstairs at the ordinary gates. Unless you are in a hurry or hauling heavy luggage, walk past the ticket machines.
The Climate Card Change in September and October 2026 — Read This Before You Panic
There is a real change happening, and English-language coverage of it is likely to be garbled. Here is the precise version, from the Seoul Metropolitan Government's own notice.
The 30-day Climate Card — the monthly unlimited pass used by Seoul residents — is being retired. Prepaid 30-day passes could be charged until 31 August 2026 and remain usable through 29 September 2026. Postpaid versions run through 30 September 2026. On 1 October 2026, prepaid and postpaid Climate Card operation formally ends. Its replacement, launched 1 September 2026 and known as the Climate Companion Pass ("Modu-ui Card"), is restricted to Seoul residents, so visitors cannot obtain it.
The part that matters to you: the short-term tourist passes are not affected. Seoul's official notice states plainly that the 1-, 2-, 3-, 5-, and 7-day Climate Cards "will be maintained as before." If you read a headline this autumn saying Seoul is scrapping its transit pass, it is describing the residents' monthly product, not the tourist passes. The 1–7 day passes remain on sale and remain the best-value option for a Seoul-only trip.
One genuine consequence: if you already own a physical Climate Card, Seoul has stated that the ₩3,000 card purchase price is not currently refundable. Keep the card — you can keep charging short-term passes onto it.
Where Your Card Will Actually Fail
Every guide tells you what works. The useful information is the failure list — seven places where a foreign card gets refused, and what to do instead.
What a Korean Phone Number Gates Off
A number of Korean apps require identity verification tied to a Korean mobile number, and in some cases an Alien Registration Card. Without one:
Blocked outright: Naver Pay, Kakao Pay, and the major food delivery apps (Baemin, Coupang Eats). No workaround exists for a short-stay visitor. Note that Kakao Pay and Naver Pay are among the payment methods now accepted at the new subway kiosks — but only if you already had a Korean account, which most visitors will not.
Partially usable: Kakao T accepts an international phone number at signup, but registering a foreign payment card can be unreliable. Our Korea taxi app guide walks through the workarounds and the alternatives (k.ride, Taba, Uber Taxi) with the exact screens.
Fully usable with no Korean number: Naver Map, Kakao Map, Papago, subway apps, and every physical transit card in this article. If you are wondering why your usual navigation app behaves strangely here, see does Google Maps work in Korea.
If you carry a Chinese, Hong Kong, Malaysian, Filipino, Macanese, or Japanese wallet app — Alipay, AlipayHK, Touch 'n Go, GCash, Mpay, PayPay — Alipay+ acceptance in Korea is broad, covering roughly two million merchants and more than 70,000 Seoul taxis, plus airport limousine buses. That solves retail and taxis. It does not solve subway gates.
Recommended Combinations by Trip Type
| Your trip | Buy this | Why |
|---|---|---|
| Seoul only, 3–5 days, any phone | Short-term Climate Card + cash | Cheapest per ride at any realistic itinerary density, and includes Ddareungyi bikes |
| Seoul + Busan or Jeju, 7–10 days | T-money + your home Visa/Mastercard | The Climate Card stops at the Seoul boundary; T-money does not |
| Shopping-heavy trip, want to avoid bank FX fees | WOWPASS (issued in the city, not at the airport) | Kiosk exchange rates beat airport counters and the card works at normal merchant terminals |
| iPhone XS or newer, iOS 17.2+ | Apple Wallet T-money + a short-term Climate Card if Seoul-only | No plastic to lose; add it through the Mobile T-money app using the "Foreigner" path |
| Android phone, Visa card only | Physical card + cash, or buy the Climate Card at a station kiosk | Visa cannot top up the mobile app, but station kiosks do accept Visa |
| 4+ paid attractions in 72 hours | Discover Seoul Pass + separate transit funding | Worth it on entry fees alone; transit is not included |
| Renting a car for part of the trip | T-money for the non-driving days | You still need transit at both ends of the rental, and One Card All Pass–branded T-money is accepted at Korea Expressway Corporation toll booths. See our guide to driving in Korea as a tourist |
If Busan is the second city on that list, the card is only half the planning — a large share of the restaurants there close between roughly 2 and 5pm, which quietly wrecks a day built around transit times. Our Busan food guide maps that gap.
One underused benefit worth calling out: the short-term Climate Card covers Ddareungyi, Seoul's public bicycle system, in two-hour blocks. Along the Han River that turns a ₩10,000 three-day pass into a genuinely different kind of afternoon — see our Han River bus and Ddareungyi guide for the routes that are actually worth riding.
Frequently Asked Questions
Can I just tap my Apple Pay or Google Pay at the subway gate like I do in London or Tokyo?
No. As of 2026 Seoul's gates do not accept foreign-issued contactless cards, and adding your home card to a phone wallet does not change that. Seoul has said it plans to begin extending acceptance to regular transit readers from 2027. Until then you need a Korean transit card. The one exception is an iPhone with T-money loaded into Apple Wallet — that is a Korean transit card living in your phone, not your own bank card.
Is the Seoul transit pass being discontinued?
The 30-day monthly Climate Card ends on 1 October 2026 and its replacement is limited to Seoul residents. The tourist passes — 1, 2, 3, 5, and 7 days — continue unchanged, per Seoul's official notice. Nothing you would buy as a visitor is going away.
T-money or WOWPASS — which should I buy?
T-money if you mainly need transit and want the lowest upfront cost. WOWPASS if you want one card that also pays at shops and restaurants and you would otherwise be exchanging cash at a bank counter. WOWPASS costs ₩5,000 up front, that fee is not refundable, and its two balances must be loaded separately — budget a few minutes to understand it before you rely on it.
Can I buy a T-money card with my credit card?
Generally no. Convenience store terminals are set up for domestically issued cards and will usually decline a foreign one for the card purchase or the top-up. Bring won. The exception is buying a single-journey ticket or a short-term Climate Card at one of the 273 upgraded station machines, which do take overseas Visa and Mastercard.
Does the Climate Card work on the airport bus or the AREX from Incheon?
No. Airport buses and wide-area red buses are excluded, as is the Shinbundang Line, GTX, and any subway section outside the Seoul zone. Budget separately for your airport transfer: AREX all-stop runs roughly ₩4,950–₩5,150; the Express is ₩13,000 bought at the station, or about ₩11,500 pre-booked online.
What happens to money left on my card when I leave?
T-money balances are refundable at convenience stores for a ₩500 fee up to a chain-specific cap, and at subway customer service offices for larger sums; the card fee itself is never returned. WOWPASS payment balance can be withdrawn as cash at a WOW Exchange kiosk for ₩1,000 per withdrawal. Unused Climate Card days and unused Discover Seoul Pass entries are not refunded. T-money never expires, so many repeat visitors simply keep the card.
Do I need a Korean phone number to use any of these cards?
No. Every physical card here works with a passport and cash. A Korean number is only required for Korean payment apps such as Naver Pay and Kakao Pay, and for food delivery apps.
I only have a Visa card. What breaks?
Topping up mobile T-money through the app, which accepts Mastercard, Amex, and UnionPay but not Visa. Everything else has a workaround: Visa works at the upgraded station machines for single tickets and short-term Climate Cards, and cash works everywhere.
Can I use one card for two people?
On the subway, no — each person taps individually and one card cannot pass two people through the gates. On buses, a driver may allow multiple fares from one T-money card, but a Climate Card pass is single-user and cannot be shared.
Is WOWPASS available at Incheon Airport arrivals?
The airport kiosks are located inside the AREX station gates in both terminals, not in the arrivals hall, and they take Korean won cash only. If you land without won, get your WOWPASS in the city instead — full-service exchange kiosks are at 70-plus subway stations and major hotels.
