T-money vs WOWPASS vs Climate Card: Seoul 2026 Guide

You cannot choose a transit card on price. Every card charges essentially the same fare.

The differences sit in how you load them and what happens to the balance. T-money takes cash only. WOWPASS lets you top up by card and doubles as a currency exchange. The Climate Card is unlimited riding within a defined zone.

So the real question is not which is cheapest but how long you are staying, how much you will move, and how much cash you intend to carry.

1. T-money basics and 2026 fares

T-money is Korea’s standard transit card, accepted on subways and buses nationwide. The card itself costs 3,000–4,000 KRW (about $2.20–2.90) at convenience stores (CU, GS25) and station vending machines. The card fee is non-refundable.

Fares with the card: 1,550 KRW (~$1.10) per subway ride and 1,500 KRW (~$1.08) per city bus ride. Tap off when you exit and transfers within 30 minutes are discounted — 60 minutes between 9 p.m. and 7 a.m.

One note on topping up: convenience stores take cash only. The good news for foreign visitors is that newer vending machines on subway lines 1–8 increasingly accept foreign-issued Visa and Mastercard for top-ups, so you’re no longer forced to carry won for every recharge.

Refunds cost a 500 KRW fee. Balances under 20,000 KRW can be refunded at convenience stores; anything larger means a trip to a T-money Town counter, with limits varying by location. Honestly, the easiest move is to just spend it down before you fly out.

2. WOWPASS: currency exchange and prepaid card in one

WOWPASS is a foreigner-focused card that combines a currency exchange kiosk, a prepaid spending card, and T-money in a single piece of plastic. Feed foreign cash — including US dollars — into a WOWPASS machine at the airport or major stations, and it loads as Korean won instantly.

Issuance costs 5,000 KRW (~$3.60), or 4,500 KRW if you reserve ahead through the app. Exchange rates track close to Seoul’s best street-level money changers, with no separate exchange fee.

One trap to know: the T-money function on the back holds a separate balance. You can’t move money from your WOWPASS spending balance to the transit side — the T-money portion needs a cash top-up at subway machines or convenience stores.

3. Climate Card: unlimited rides, tourist-friendly passes

The Climate Card (기후동행카드, gihu donghaeng kadeu) is Seoul’s unlimited-ride pass, and it now comes in short-term versions built for tourists: 1-day 5,000 / 2-day 8,000 / 3-day 10,000 / 5-day 15,000 / 7-day 20,000 KRW (roughly $3.60 / $5.80 / $7.20 / $10.80 / $14.40).

Add a one-time 3,000 KRW (~$2.20) card fee. You buy it at station vending machines — payment is primarily cash, though machines accepting foreign-issued cards are gradually rolling out. There’s also a 30-day pass at 62,000 KRW, but that’s overkill for a short trip.

4. The Korea Tour Card is discontinued

The tourist-oriented “Korea Tour Card,” once a standard recommendation, is now listed as discontinued in current local guides. Plenty of older blog posts still push it — ignore them.

Its successor, a tourist-design T-money card, works exactly like regular T-money. Stock varies by store, so don’t build your plans around finding one.

5. Stay-length simulation: which card wins

Let’s assume 3–4 subway or bus rides per day — a normal sightseeing pace — at 1,550 KRW per ride. Card fees are about 3,000 KRW either way, so we exclude them from the comparison.

The break-even points: 7 rides for the 3-day pass, 13 rides for the 7-day pass. If your trip is Seoul-centered, the Climate Card pulls ahead the moment you stay longer than three days.

Getting from the airport into the city is covered in the Incheon-to-Seoul comparison, and finding your route once you’re tapping in is in the map app guide.

6. The verdict by traveler type

For a light-transit 2–3 night trip, or any itinerary with day trips outside Seoul, plain T-money is all you need — it works everywhere. If you’d also like to skip currency-exchange errands, WOWPASS gives you spending money and transit in one card.

Riding 3+ times a day and staying inside Seoul? The Climate Card short-term pass is the cheapest option, hands down. The local move: pair it with a small T-money balance just for the airport train.

One honest caveat: the Climate Card only pays off if you actually ride that much. Plenty of visitors buy the pass, then walk everywhere because Seoul neighborhoods are dense — and the pass money is wasted. If you’re a walker, or your hotel sits in the middle of everything, don’t buy it.

If you’re still torn at the airport, just grab a plain T-money at the convenience store and go. It’s never the wrong answer — at worst it costs you a few dollars versus the perfect pick, and you’ll have spent zero vacation minutes doing card math.

A transit card is hard to switch mid-trip. Choosing again in the second half of your stay means eating whatever balance and fees you have already committed.

Frequently asked questions

Which card should I actually buy?

For a three-day trip T-money and the Climate Card come out nearly the same. From four days up, if you are mostly moving around central Seoul, the Climate Card wins; if your trip includes airport runs or day trips outside the city, stay with T-money.

What does the Climate Card cost?

1-day 5,000 / 2-day 8,000 / 3-day 10,000 / 5-day 15,000 / 7-day 20,000 KRW, plus a one-time 3,000 KRW card fee. You buy it at station vending machines, and payment is primarily cash.

Does the Climate Card cover the airport train?

No. AREX and intercity buses are outside its coverage. Getting that wrong throws off the whole calculation, so plan airport transfers on T-money or a separate ticket.

What is the T-money base fare?

About ₩1,550 on card, with distance added on top. Changing lines inside the fare gates costs nothing extra, and subway-to-bus transfers are discounted if you tap within 30 minutes of getting off.

How is WOWPASS different?

It combines a currency exchange kiosk, a prepaid spending card and T-money in one piece of plastic. Feed foreign cash into a WOWPASS machine at the airport or a major station and it loads as won instantly. Issuance costs 5,000 KRW, or 4,500 KRW if you reserve through the app first.

Can I still get the Korea Tour Card?

No, it has been discontinued. Older articles still mention it, but there is no reason to factor it into your decision now.

Climate Card vs T-money: which is cheaper?

Do the arithmetic on rides. T-money charges about ₩1,550 per subway ride. A 3-day Climate Card is ₩10,000 plus the one-time ₩3,000 card, so it breaks even at roughly nine rides — three a day. The 5-day pass (₩15,000 + ₩3,000) needs about twelve rides, the 7-day (₩20,000 + ₩3,000) about fifteen. If you ride the subway or city buses three or more times a day inside Seoul, the Climate Card is cheaper; if you take the airport train or day trips outside the city, those are on T-money anyway.

Can the Climate Card be used as T-money?

No. It is a separate card that only covers Seoul subway lines within the city, Seoul city buses and Ttareungyi bikes. It cannot pay for the AREX airport train, Gyeonggi buses, taxis or shops. Most visitors carry both: a Climate Card for daily rides and a T-money card for everything else.
