Korea Transport Cards Guide (2026): T-money & Passes
For most visitors, the answer is refreshingly simple: just get a T-money card. It works on subways, buses, taxis and even convenience-store snacks, everywhere in Korea — no registration, pay as you go.
The only real reason to look further is if you're a heavy Seoul rider (think 4+ trips a day, all within the city). Then Seoul's Climate Card unlimited pass can save you money — as long as you know its Seoul-only limits.
Hi there. I put this together because the card landscape genuinely changed in 2024–2026 — new passes, a rebrand, even new credit-card kiosks — and a lot of older guides are now out of date. Sources are cited inline and listed at the end.
A quick, honest note up front: every price here is approximate for 2026 and fares were revised recently, so treat the numbers as a guide and confirm at the point of sale before you tap in.
T-money card: the default for nearly everyone
T-money is Korea's standard rechargeable transit card — the exact same one locals use. Tap to pay on the subway, city buses, most taxis, and even at convenience stores, vending machines and coin lockers (source: Trazy 2026; discoverrealkorea 2026).
Here's what matters, in plain numbers:
- Card cost: ~₩2,500–4,000, non-refundable (character/designer editions cost more) (source: Trazy; unniespicking 2026)
- Base subway fare: ~₩1,550 for the first 10 km, then +₩100 per extra 5 km (source: Trazy; KoreaPeek 2026 — verify, fares are periodically revised)
- Where to buy: any CU, GS25, 7-Eleven or Emart24, plus subway station machines and Incheon Airport counters (source: KoreaPeek; askkoreatravel 2026)
- Top-up: mostly Korean Won cash only at CVS counters and station machines; max load ~₩500,000 (source: Trazy 2026)
One 2026 upgrade worth knowing: since around March 2026, Seoul Metro added 440 kiosks across 273 stations (Lines 1–8) that take foreign credit cards (Visa, Mastercard, JCB, UnionPay, Amex) and sell both T-money and Climate Card passes — no Korean cash needed (source: Trazy 2026).
The quiet superpower is the transfer discount. Tap onto a bus or subway within 30 minutes of tapping off, and you only pay the distance difference — not a second base fare (source: koreapeek; citygramseoul 2026). It's capped at 4 transfers a day, and the window stretches to 1 hour between 21:00–07:00 (source: Trazy; korvia 2026).
💡 One rule you can't skip: you MUST tap out when leaving a bus. Subways tap you out automatically at the gate, but buses need an active tap-off — miss it and you lose the transfer discount and may be penalized on your next ride (source: koreapeek 2026).
⚠️ There's also a Tmoney Travel Card — a tourist version of T-money (~₩4,000) that adds partner discounts at shops and attractions across Seoul, Gyeonggi and Busan. Multiple 2026 guides report it has replaced the old "Korea Tour Card" (source: askkoreatravel; Trazy 2026). The transit function is identical to plain T-money, so buy it only if you'll actually use the merchant perks.
Climate Card: Seoul's unlimited pass (and its gotchas)
The Climate Card (기후동행카드) is Seoul's unlimited-ride pass — charge it once and ride as much as you like for the period (source: Seoul Metropolitan Government official site). It comes in monthly tiers and short-term tourist passes.
30-day (monthly) tiers (source: Seoul Gov, 2026):
| Tier | Price (30 days) |
|---|---|
| Subway + bus | ~₩62,000 |
| + Ttareungi public bike | ~₩65,000 |
| + Hangang Bus | ~₩67,000 |
| + Ttareungi and Hangang Bus | ~₩70,000 |
Ages 13–39 get roughly ₩7,000 off each tier with registration and age verification — open to foreigners too (source: Seoul Gov; korealivingguide 2026).
Short-term tourist passes — the ones most travelers want (source: Seoul Gov, 2026):
| Duration | Pass price | Roughly worth it at |
|---|---|---|
| 1-day | ~₩5,000 | 5+ rides |
| 2-day | ~₩8,000 | — |
| 3-day | ~₩10,000 | 7+ rides |
| 5-day | ~₩15,000 | 10+ rides |
| 7-day | ~₩20,000 | — |
Add a one-time ₩3,000 physical card on top (reusable for future trips). Short-term passes cover subway + city bus only — no bike or river bus (source: korealocally 2026; Seoul Gov).
Now the part that trips people up. The Climate Card is Seoul-only, and the exclusions are specific:
- Shinbundang Line (신분당선): not covered, even inside Seoul (source: Seoul Gov; korealocally 2026)
- Subway lines outside Seoul and non-Seoul-licensed / intercity / airport buses: not covered (source: Seoul Gov)
- Incheon Airport: the biggest gotcha — you cannot start a trip at Incheon T1/T2 with a Climate Card. On the Airport Railroad (AREX) it only works on the Gimpo Airport ↔ Seoul Station section (source: korealocally; flipkorea 2026)
- Boarding in-zone but getting off outside Seoul: staff will collect an extra fare (source: Seoul Gov)
⚠️ iPhone users, take note: the Climate Card mobile pass runs on Android (OS 12+) only. On iPhone you'll need to buy the physical card (source: Seoul Gov).
So the Climate Card is a great deal for someone circling central Seoul all day — but don't rely on it for the airport run, and keep a T-money in your pocket for anything outside the city.
The other options: WOWPASS, Discover Seoul Pass, M-PASS
Beyond the two big players, a few specialty cards fit specific travelers.
WOWPASS is a payment card + currency exchange + T-money, all on one card, built for foreigners (source: WOWPASS official; inmykorea 2025). At a kiosk you insert home-country cash (USD, EUR, JPY and ~20 currencies) and it loads Korean Won at rates usually better than airport counters. The card then carries two separate balances: a spending balance for shops and restaurants (no foreign-transaction fees), and a separate T-money transit balance you top up yourself, just like a normal T-money card (source: inmykorea 2025; korea-insider 2026).
- Issue fee: ~₩5,000, non-refundable (source: Klook; inmykorea 2025)
- Cash withdrawal: up to ₩100,000 per withdrawal, ~₩1,000 fee each (source: inmykorea 2025)
- Best for: travelers whose bank charges high foreign-transaction/ATM fees and who want one card for spending + transit
Discover Seoul Pass is a sightseeing pass first, transit second. It gives free entry to 70+ attractions (N Seoul Tower, Gyeongbokgung, Lotte World, Nami Island and more) and the physical card also works as T-money, with free AREX/bike/tour-bus rides on some tiers (source: discoverseoulpass.com; Klook 2026). It comes in 24/48/72/120-hour and "Pick 3" options; pricing is vendor-dependent — roughly ~₩35,900–49,000 for 24 hours (verify), and the old 48-hour pass was reportedly replaced by a "Pick 3" theme-park pass (source: Trazy; NOL World; kkday). Worth it only if you're hitting many paid attractions in a short window.
M-PASS is a prepaid metro-area pass for foreign visitors — subway, city bus and Airport Railroad, up to 20 rides/day (source: NOL World; VisitKorea). Reported prices run ~₩15,000 (1-day) to ~₩64,500 (7-day) (source: NOL World 2026 — verify). It's niche: for pure Seoul riding, the Climate Card short-term pass is cheaper.
Here's everything side by side:
| Card / Pass | Cost (2026, approx.) | What it covers | Best for |
|---|---|---|---|
| T-money | Card ~₩2,500–4,000 + pay-per-ride (base ~₩1,550) | Subway, bus, taxi, CVS — nationwide | Almost everyone; flexible / day trips |
| Tmoney Travel Card | ~₩4,000 + pay-per-ride | Same as T-money + partner discounts | Tourists who'll use merchant perks |
| Climate Card (short-term) | Card ₩3,000 + ₩5k–20k pass | Unlimited Seoul subway + city bus | Heavy Seoul riders (4+/day) |
| Climate Card (30-day) | ~₩62,000–70,000 | Unlimited Seoul subway/bus (+bike/river tiers) | Residents / long Seoul stays |
| WOWPASS | ~₩5,000 issue fee | Card payments (FX) + separate T-money | Avoiding FX/ATM fees; spend + transit |
| Discover Seoul Pass | ~₩35,900–49,000 (24h) | 70+ attractions + T-money/AREX | Sightseers hitting many attractions |
| M-PASS | ~₩15,000–64,500, 20 rides/day cap | Metro-area subway/bus + Airport Railroad | Niche capped metro + airport transit |
Which card should you actually buy?
Here's the short version, matched to how you travel. If you only remember one line: when in doubt, get a T-money.
- Short trip / casual sightseeing / day trips outside Seoul → plain T-money. No commitment, works nationwide, transfer discounts, top up as you go (source: Trazy; KoreaPeek).
- Heavy Seoul rider (4+/day), several days in the city → Climate Card short-term pass (e.g. 3-day ~₩10,000 or 5-day ~₩15,000). Keep a T-money too for the airport and any Shinbundang/outside-Seoul trips (source: Seoul Gov; korealocally).
- Arriving/leaving via Incheon Airport → T-money or WOWPASS. AREX and the limousine buses both take T-money, and the Climate Card can't start a trip at Incheon (source: korealocally; flipkorea).
- Hate carrying cash / high foreign-card fees → WOWPASS, accepting the ~₩5,000 fee for spending + transit in one card (source: WOWPASS official; inmykorea).
- Attraction-heavy itinerary (palaces, towers, theme parks) → Discover Seoul Pass — the transit function is a built-in bonus (source: discoverseoulpass.com).
💡 A combo that rarely goes wrong: T-money for flexibility + a Climate Card short-term pass if you end up commuting hard around central Seoul. You're covered nationwide and still capped on the days you ride the most.
Summary
For nearly every visitor, a T-money card is the right default — cheap, nationwide, no commitment. Add a Climate Card short-term pass only if you're a heavy Seoul rider, and reach for WOWPASS if you want spending and transit on one card.
The Climate Card is Seoul-only and can't start a trip at Incheon Airport — so keep a T-money for the airport no matter what.
Final thoughts
- Honestly, most people overthink this. A T-money card from any convenience store handles 95% of trips, and you can decide on a pass later once you see how much you actually ride.
- The Climate Card is a genuinely good deal — but only inside its box. Its Seoul-only coverage and the Incheon exclusion are where travelers get caught out, so it's worth reading those limits twice.
- The names keep shifting (Korea Tour Card → Tmoney Travel Card, Discover Seoul Pass tiers, new credit-card kiosks), which is exactly why you should trust current prices at the point of sale over any single guide.
⚠️ Every price and rule here is approximate for 2026 and Korean fares were revised recently — always confirm the current fare and coverage at the machine, kiosk or official site before you tap in.
