WOWPASS vs T-money vs Climate Card: Which Seoul Transit Card Fits Your Trip

Three cards, one question: which one won't let you down on day one? My answer is the boring one. Plain T-money works on buses, subways and taxis nationwide, and the other two only win in specific situations.

Why you can't just tap your US card yet

Seoul's October 2025 plan moves to overseas-card payment at the gates in stages: bus readers first, then a swap of the Line 1–8 subway gate readers in 2027, and the wider metro area by 2030. No tap-your-Visa date is set yet, so you need a transit card.

Since March 17, 2026, new ticket machines in 273 Line 1–8 stations take Visa, Mastercard and other foreign cards for Climate Card passes and single-ride tickets, with an average 3.7% service fee. A single ride costs 1,650 won against 1,550 won on a card, and transfer discounts need a transit card.

T-money: the plain card I'd hand you first

• Where to buy: Tmoney's visitor version, the Tmoney Travel Card, costs 4,000 won at convenience stores and Incheon Airport's staffed bus ticket counters.
• Top-ups: Korean won cash at convenience stores and station machines, in 1,000-won steps, 1,000 to 90,000 won per top-up. A card holds up to 500,000 won.
• What it covers: subways, buses, taxis, airport buses and express buses, nationwide.
• Transfers, in the Seoul area: tap when you get off. Board the next bus or train within 30 minutes (60 minutes from 9 p.m. to 7 a.m.) and you pay one base fare for the whole trip, plus distance extras, for up to four transfers. Other cities set their own rules.
• Refunds: 500-won fee; the card price isn't refunded. GS25 handles balances under 20,000 won, CU and Emart24 up to 30,000. Partial refunds: Tmoney Town (Seoul Station Exit 10) or a station service center.

My advice: top up 10,000 or 20,000 won at a time, so there's no big balance to refund at the airport. If you head to Busan or Daegu, the same card comes with you.

WOWPASS: T-money plus a prepaid spending card

WOWPASS is a prepaid card for foreign visitors: insert the chip to pay in shops, tap it like T-money on buses and subways, with a separate balance for each.

• Where to get it: walk up to any WOWPASS machine, including the CU stores at Incheon Terminal 1 (store No. 1) and Terminal 2 (store No. 3), which take won only, with no exchange or withdrawals. Tmoney also sells a WOWPASS-enabled Tmoney Travel Card+ for 6,000 won at convenience stores.
• Fee: 6,000 won for the first registration, not refundable. No fee for currency exchange or payments, according to WOWPASS.
• Top-ups: cash in 16 currencies at WOWPASS machines, or in the app with an overseas card (Mastercard and JCB; Visa through PayPal).
• The T-money side: fill it from the WOWPASS balance in the app, or with won cash at station machines and convenience stores. Money can't move back from T-money to WOWPASS.
• Cash out: up to 100,000 won per withdrawal at a WOW Exchange machine, 1,000 won each time, after you register the card in the app.

My take: WOWPASS earns its fee if you want to dodge your bank's foreign-transaction fees, expect shops whose terminals turn away foreign cards, or want won without hunting for an exchange counter. If your US card already works well for you abroad and you only need rides, plain T-money does the job.

South Korea WOWPASS Prepaid Payment and T money Card

• Who it suits: travelers who'd rather have the card reserved before they land.
• Pickup: at a WOWPASS machine. The listing names Incheon Airport Terminal 2 (CU store No. 3, won only; the listing doesn't name Terminal 1) and Gimpo Airport, Hongik Univ., Myeongdong, Seoul, Gangnam and Dongdaemun History & Culture Park stations.
• Before you buy: all sales are final.

Climate Card: unlimited rides, but only in Seoul

• Prices: 1 day 5,000 won, 2 days 8,000, 3 days 10,000, 5 days 15,000, 7 days 20,000.
• Clock: it starts the day you charge it and lasts until the final day's last train (the city counts that as running to 4 a.m.). No charging in advance.
• Covers: subway stations inside Seoul and Seoul-licensed city and village buses, including night buses, even where those buses run outside Seoul. You may ride from Seoul and get off at Incheon Airport Terminal 1 or 2.
• Doesn't cover: the Sinbundang Line, GTX, subway stations outside Seoul, wide-area and airport buses, buses licensed by other regions, or taxis. Boarding at the airport stations isn't allowed. Since October 1, 2026, subway stations in cities such as Gimpo, Goyang, Gwacheon, Guri, Seongnam, Hanam and Namyangju are out.
• The card: a physical card, 3,000 won at the new machines on Lines 1–8. iPhones can't hold the pass, and the Android app needs a Korean ID check, so most visitors buy plastic. One rider per card.
• Refunds: plan as if there are none. Seoul refunds only inside the valid period, minus the rides you took and a 500-won fee, and the card has to be registered on Tmoney's website, which asks for a Korean phone number in your name or a foreigner registration number. A 2024 city Q&A sends foreigners who can't register to Tmoney Town in person.

The 30-day Climate Card ended October 1, 2026. On a longer stay, charge a new short-term pass on the same card when one runs out.

Does the Climate Card pay off?

The math: (pass price + the 3,000-won card) ÷ the 1,550-won subway fare, rounded up; a "ride" is one journey with its transfers. All-bus riders (1,500 won) need slightly more.

How to read it: on a 3-day pass you need about three rides a day before it beats T-money, on a 5-day pass about two and a half, and on a 7-day pass just over two. Long subway rides help, since T-money adds 100 won per 5 km past the first 10 km. If you chain passes on one card, the 3,000 won counts only once.

My opinion: a 5- or 7-day pass is good value for a busy Seoul-only week. I'd skip the 1-day pass; six rides is a lot for one day.

The iPhone route: MobileTmoney in Apple Wallet

• Requirements: iPhone XS or XR or later on iOS 17.2 or later, or Apple Watch Series 6 / SE (2nd gen) or later.
• Setup: no sign-up for international users; top up in the app with Apple Pay.
• Cards: Mastercard, American Express, UnionPay and JCB.
• Where: buses and subways across Korea.
• Leftovers: Tmoney refunds mobile balances through the app to a bank account in your name, not at station counters. Top up only what you'll ride.

On Android, Tmoney's KOREA TOUR CARD app lists Visa top-ups, but it was last updated in April 2025; treat it as a backup.

What I'd tell you, depending on your trip

A week in Seoul, out every day: T-money for the airport ride, then a 5- or 7-day Climate Card from the next morning. If it's still valid on your last day, it covers the train back to Incheon too. Keep the T-money for taxis and anything outside Seoul.

Seoul plus Busan or Daegu: T-money first. A Climate Card only helps on your Seoul days.

A shopping-heavy trip: WOWPASS, with some money on the T-money side for rides.

Traveling with kids: register a child's T-money as a child card at a convenience store or station information center (ages 6–12) with ID. Under-6s ride free with an adult.
