Yes, but only at a ticket machine. Since March 17, 2026, a foreign Visa or Mastercard buys single tickets and 1-7 day Climate Cards at 440 machines in 273 subway stations, for an average 3.7% extra fee. Tapping the card at the gate still does not work. Everything below is dated as of Oct 28, 2026.
Friends keep asking me this before their autumn trips, and I carry only Korean cards, so I cannot test a foreign Visa at a kiosk myself. What follows is city statements and press reports, conflicts left visible. The last time a visitor needed rides, I lent a spare T-money card (that post has the tap-off rule), and it only worked because the friend was staying with me.
Can I tap my Visa at the Seoul subway gate today?
No. The table is the whole answer, row by row. Climate Card (기후동행카드, gihu-donghaeng kadeu, literally “climate-companion card”) is Seoul’s unlimited-ride pass, and Tmoney (티머니) is the company behind Korea’s main transit card.
| What you want | Foreign card today? | Status | Basis |
|---|---|---|---|
| Single-journey ticket at a kiosk | Yes | Since Mar 17, 2026 | City launch, JoongAng Daily |
| 1, 2, 3, 5 or 7-day Climate Card | Yes | Since Mar 17, 2026 | Same |
| Old 30-day Climate Card (prepaid, postpaid) | Gone | Recharge ended Aug 31, last prepaid use Sep 29, postpaid Sep 30; ended Oct 1 (mobile card not re-checked) | Seoul city transit site, Card Gorilla |
| Modu Card (Climate Pass), the successor monthly pass, announced as Climate Card Plus | Not reported | Launched Sept 1, 2026; Seoul residents only; I found no foreign-card reports | Seoul city FAQ, Herald |
| Tap at the subway gate | No | EMV gates planned for 2027 (city’s 2025 roadmap) | Korea Times |
| Tap on a bus | Not yet | Seoul buses first in 2027, no official month | Korea Herald |
| Top up Apple Pay T-money with a foreign card | Unverified | Sources conflict, see below | Korea Times vs a May 2026 guide |
The machines also take KakaoPay and NaverPay, and the launch was timed to coincide with the BTS Gwanghwamun show on March 21. The single-journey ticket price is 1,650 won, unchanged in the May 2026 guide I read.
The monthly rows trap long-stay visitors, because many guides still describe a pass that is gone. The old 30-day card kept recharging to Aug 31 and stopped working Oct 1 (prepaid last use Sep 29). Its successor, announced as Climate Card Plus for Jul 1, was delayed and renamed the Modu Card (Climate Pass); it launched Sept 1 for Seoul residents only. The 1-7 day passes stayed as they were.
The latest kiosk coverage I found is the April first-month report. Check the screen at the machine.
If you are a new arrival still waiting on an ARC (외국인등록증, oegugin deungnokjeung, the Alien Registration Card) or a bank account, the split is simple. Kiosk tickets and 1-7 day passes work with your home card today. For a monthly pass, the Modu Card is for Seoul residents only, and K-Pass-style registration generally wants a Korean-bank-linked card, so check eligibility before relying on it. A cash-loaded T-money card works either way, and its price varies by design.
What does the 3.7% kiosk fee add to each ticket and pass?
Foreign-card purchases carry an additional service fee that averages 3.7%. It is an average, not a fixed rate, and I found no per-card breakdown. The cost is charged to the rider. I ran 3.7% across the price ladder as an illustration, and for a first-time buyer I added the 3,000-won plastic card and counted how many 1,711-won single rides it takes before the pass wins.
| Item | Price (₩) | ~3.7% fee | Price + fee | Rides to beat singles, first-timer |
|---|---|---|---|---|
| Single ticket | 1,650 | ~61 | ~1,711 | – |
| 1-day pass | 5,000 | ~185 | ~5,185 | 5 (in a day) |
| 2-day pass* | 8,000 | ~296 | ~8,296 | 7 (in 2 days) |
| 3-day pass | 10,000 | ~370 | ~10,370 | 8 (in 3 days) |
| 5-day pass | 15,000 | ~555 | ~15,555 | 11 (in 5 days) |
| 7-day pass | 20,000 | ~740 | ~20,740 | 14 (in 7 days) |
*Launch coverage gave only the ladder’s ends (5,000 to 20,000 won), so the 2-day price comes from the city’s own October 2024 tourist-pass announcement and a 2026 guide. The 1,711-won single ride is the 1,650-won ticket plus fee; my earlier post uses 1,550 won for card fares, so against that the break-even can be a ride or two higher. The last column adds the 3,000-won card to the pass price and assumes the fee lands on the pass only; if it also hits the card, add about 111 won. I have not seen reporting that says which.
Per day, the 7-day pass breaks even at 2 rides and the 5-day at about 2.2, even after the card. The 3-day needs about 2.7, the 2-day about 3.5 and the 1-day 5. A visitor doing four rides a day is clearly ahead on any pass of three days or more.
Between Mar 17 and Apr 17, an average of 9,158 people a day paid with overseas cards or simple-pay apps, about 70 million won a day (roughly 7,600 won each, by my division). Visa was the most-used card with 3,788 transactions, WeChat Pay led the simple-pay apps, and the 3-day pass was the most popular at about 35%, ahead of the 5-day pass at 24%.
Why do so many guides disagree?
Because the answer changed three times in six months, and each version got written up. Here is the ledger.
| Date | What was said | What was true |
|---|---|---|
| Oct 17, 2025 | City tells the Korea Times foreign cards will buy and recharge transit cards at new kiosks “by year-end” | Not available |
| Jan 8, 2026 | Seoul’s official clarification: not yet, pending talks with the Financial Services Commission on who bears the overseas fee | Correction to the above |
| Mar 16-17, 2026 | Announced, then launched, with a 3.7% average fee | Kiosk purchases work |
| Jun 17-Sept 1, 2026 | Plus delayed from Jul 1 and renamed Modu Card (Climate Pass), launched Sept 1; old 30-day card extended to Oct 1 | March’s “30-day review” line is obsolete |
| Sept 17-22, 2026 | Tmoney’s open-loop deal for 2027 buses signed and announced | Plan, not service |
So the claims you will meet online sort out like this. “Cash only” was largely true for kiosks until March (Android users could already top up through an app, per the Korea Times) and is out of date now. “Just tap your card at the gate” is not true today. “Foreign cards work by the end of 2025” was a promise the city walked back in January. “Buy a 30-day pass with your overseas card” and “use the mobile Climate Card with it” are wrong for a different reason than in March: the 30-day card ended Oct 1 (mobile card status not re-checked).
The Oct 2025 piece was wrong about the date, not the destination, which is why it is still quoted. A quick test for any guide: does it name the 440 machines or the 3.7% fee, and does it separate kiosk purchase from gate tap? If it does neither, it may be built on the 2025 promise. A step-by-step guide dated May 29, 2026, two and a half months after launch, did not mention kiosk card payment at all, so publication date is not a freshness guarantee.
What does the 2027 plan actually say?
In mid-September 2026, Tmoney signed with Visa, Mastercard, UnionPay, JCB and Hana Card, which will be the domestic acquirer, to build an EMV open-loop system (EMV is the chip standard behind contactless Visa and Mastercard taps). Seoul city buses come first in 2027, then Incheon buses and airport buses, with development and testing running through the end of 2026.
Only part of this is confirmed, and the list below keeps the two apart.
- Confirmed (Korea Herald): the five-party agreement, buses first, 2027 start, testing through 2026.
- No official month: Hana Card told Korean press (SBS Biz, Toyo Economy) it plans a January 2027 launch, while the Korea Herald and Visa’s own release give no month, so I treat it as a company plan, not a city commitment.
- Different document: the city’s October 2025 roadmap upgrades all Line 1-8 subway terminals to EMV in 2027 and widens to village buses and private rail from 2028 to 2030, at a cost of at least 50 billion won (about $35.2 million). The Tmoney deal is bus-first, so I would not promise a gate tap in 2027.
My guess is the pressure behind the plan is volume: Korea had about 16.4 million foreign visitors in 2024 (a single-source figure, from the Korea Times). For a guest landing in early 2027, I would plan on the kiosk route and treat any bus tap as a bonus, since no launch month is confirmed.
The item I cannot settle is Apple Pay. Apple Pay T-money launched on July 22, 2025 as prepaid top-up transit, with no post-paid, Climate Card or K-Pass support. The Korea Times quoted a city plan in October 2025 for foreign cards to top it up “this year,” while a May 2026 guide says Apple Pay does not support T-money at all, which contradicts the 2025 launch, so I give that guide little weight. Nothing newer turned up, so treat it as unverified.
Which option for which guest?
My own commute is two rides a day on one line, which suited the old 30-day card I used until it was wound down this fall. Guests ride differently, and the short passes are a different calculation.
| Guest | My pick | Why |
|---|---|---|
| Weekend visit, 2 days, hotel | 2-day pass at a kiosk, about 11,300 won with card and fee | Singles for 7 rides cost about 11,977 won, and the pass covers extra detours |
| 5-day visit, about 3 rides a day | 5-day pass, about 18,555 won with card and fee | 15 single rides would be about 25,665 won, so about 7,110 won saved |
| 7-day visit | 7-day pass, about 23,740 won with card and fee | Break-even is 14 rides, which is two a day |
| New arrival, no Korean card, 30+ days | Repeat 7-day passes, or a cash-loaded T-money card | The old 30-day card is gone and the Modu Card is residents-only with no foreign-card reports, so the kiosk’s 7-day pass is the longest sure option |
If a friend flew in for five days, I would walk them to the kiosk at the first station and have them buy the 5-day pass with their own Visa, rather than lend my card. For anyone staying past a week with no Korean card, I would plan on repeat 7-day passes or cash T-money until they hold an ARC and a Korean card, and only then look at the Modu Card. If you are reading this after a 2027 bus launch, the table above is the first thing I would re-check.
Before the flight, tell the guest three things: bring a Visa or Mastercard, the two networks named for the kiosks; expect the fee line on the screen; and do not count on Apple Pay. For the monthly side, my earlier post on Climate Card Plus covers the setup (renamed Modu Card since; use the dates above), and my Apple Pay vs KakaoPay comparison covers phone payments.
