Seoul Transit Card 2026: Climate Card vs T-money
From March 17, 2026 Seoul takes overseas cards at 440 machines in 273 stations (3.7% fee). Short passes from 5,000 won a day; the 30-day pass ends Oct 1.
Korean services block visitors at two places: identity verification and payment method. Transit had the same wall β topping up a transit card needed cash, and overseas-issued cards were usually rejected by the machines.
That wall came down in March 2026. And in September of the same year, the card itself is due for a significant change.

Half of this piece is the part the table leaves out. It lists where the card works; it does not list where it does not β and that is where visitors actually lose money.
Airport buses and the Shinbundang Line both sit outside it.
What the Climate Card actually is
It is an unlimited flat-rate transit pass operated by the Seoul Metropolitan Government. Top it up once and ride eligible lines without a trip limit for the period you bought.
| Pass | Price |
|---|---|
| 1 day | 5,000 won |
| 2 days | 8,000 won |
| 3 days | 10,000 won |
| 5 days | 15,000 won |
| 7 days | 20,000 won |
| 30 days (standard) | 62,000 won β ending October 2026 |
The physical card itself costs 3,000 won, and you top it up after that. It is sold at the new ticket machines inside lines 1β8 stations and at nearby convenience stores. What travellers actually use is the 1 to 7-day short pass.
Two conditions attach to short passes. Ttareungi public bicycles and the Han River bus are not included, and the validity period starts on the day you top up β advance loading is not possible. Buying the day before you arrive does not work.
What changes on October 1, 2026
This affects trip planning directly, so it goes first. All of this is per Seoul's own notice.
| Item | What happens |
|---|---|
| Prepaid 30-day pass | Top-up until August 31 Β· usable until September 29 |
| Postpaid card | Usable until September 30 |
| Formal end date | October 1, 2026 |
| Short passes (1, 2, 3, 5, 7 days) | Continue unchanged |
| Replacement | Climate Companion Pass, built on the national K-Pass, launching September 1 |
For a traveller the conclusion is simple: the pass you use is not going away. What ends is the 30-day pass that Seoul residents topped up monthly, replaced by a scheme carrying resident-focused benefits.
It is different if you are staying more than a month β a language student or exchange student who had budgeted around the 62,000-won monthly pass needs to recalculate, and how the replacement applies to foreign residents will need checking after launch.
The day overseas cards started working
From March 17, 2026, Seoul began accepting Visa, Mastercard and other overseas-issued credit and debit cards at 440 new transit ticket machines across 273 stations on subway lines 1 to 8. KakaoPay and NaverPay opened at the same time.
It applies first to short pass top-ups and single-journey tickets. The 30-day pass was left for later review.
The timing was not accidental. Seoul said it moved pre-emptively ahead of the BTS comeback concert on March 21, expecting an influx of foreign visitors. One concert pulled forward a payment infrastructure upgrade.
One condition attaches. Paying with an overseas-issued card adds an average 3.7% service fee.
Where it does not work matters more
But the word unlimited misleads. There is a clear boundary. Straight from Seoul's published guidance:
| Category | Included | Excluded |
|---|---|---|
| Subway | Seoul-area subway plus some Gyeonggi sections | Shinbundang Line Β· GTX Β· subway outside Seoul |
| Bus | Seoul-licensed city and village buses, including late-night | Express buses Β· airport buses Β· buses licensed elsewhere |
| Other | Ttareungi and Han River bus vary by pass type | Neither is included in short passes |
Two of those bite travellers specifically. Airport buses to and from Incheon are out, and the Shinbundang Line commonly used towards Gangnam is out. Budget those separately.
iOS users have exactly one option
The mobile card runs on Android through the Mobile T-money app (OS 12 or later). On iOS, the physical card is the only option.
If you use an iPhone, do not plan on mobile top-up β buy the 3,000-won physical card at a station. That is a precondition, not an inconvenience.
Refunds have conditions too. The refund equals your loaded balance minus actual usage minus a 500-won fee, and no refund is possible once the validity period has expired. Foreign visitors without a Korean bank account must visit T-money headquarters for a cash refund β which is also to say that if the remaining balance is small, it is not worth the trip.
Is it worth buying β the arithmetic
A flat-rate unlimited pass pays off only if you ride a lot. The calculation is simple: count how many subway and bus rides you take in a day and multiply by the single-journey fare. If that beats the short pass price, the pass wins.
What actually decides it is the shape of the itinerary. And the map app you build that itinerary with behaves differently in Korea β walking directions do not appear where you expect.
| Itinerary type | Verdict |
|---|---|
| Three or more stops a day (palace, Myeongdong, Hongdae, Seongsu) | Usually worth it |
| Staying in one area and walking | Not worth it. Single-journey tickets are better that day |
| Airport transfer day | Outside the pass. Leave it out of the calculation |
| Days outside Seoul (Busan, Gyeongju, Jeonju) | Useless. Count only your Seoul days when choosing a pass length |
What this means where you are
| Item | What to actually do |
|---|---|
| The 3.7% | It is a fee on overseas card payment. On a 20,000-won seven-day pass that is around 700 won, cheap for the convenience β but it applies each time you top up separately. Load what you need in one go |
| When to buy | Do not try to buy it on arrival day. Airport buses and the airport railway fall outside the coverage, so buy at a city subway station after you get in. And since advance loading is impossible, buying early gains you nothing |
| Payment failure | Overseas card authorisation varies by issuer and country. If the machine refuses you, a nearby convenience store is the fallback. Carry some cash |
| Travelling together | The pass is single-person. Two people cannot tap one card, so buy one each |
| Staying a month or more | The 30-day pass ends October 1, 2026. Check the replacement scheme separately if your plan runs longer than a month |
| Verifying | Prices and coverage change with city policy. Read Seoul's official notice once before departure β the numbers in this article came from it |
