The 3 Korean transit cards — which one is actually the right choice?

If in doubt, T-money. That's the conclusion. Seoul, Busan, and Jeju can all be ridden with a single card, and its versatility — you can pay at convenience stores with it as-is — is unmatched.

However, if you're "Seoul only, riding a lot every day," the Climate Card is better, and if you "want to handle cash exchange all at once," WOWPASS means fewer steps. The dividing line comes down to just two things: "How many days will you be there?" and "Do you need to exchange cash?"

And what's surprisingly little known: the refund rules and how much to load. The card fee is not refunded — only the balance comes back. So many people don't know this and panic on their departure day. Here are the prices, where to buy, and refund conditions for all three cards, laid out so you can decide the moment you land at the airport.

The three cards' prices and coverage, in one table

First, the big picture. Rather than fine specifications, once you know how much you pay, where you can buy it, and how far it covers, you can choose your card.

Card	Physical card fee	Where to buy	Coverage
T-money	4,000 won	Convenience stores, subway stations	Most cities in Korea (subway, bus, taxi, partner stores)
Climate Card	3,000 won + pass fee	CU, GS25, 7-Eleven	Some transit within Seoul (some lines excluded)
WOWPASS	Issued at dedicated machines	WOWPASS machines (double as exchange machines)	T-money transit function + card payment + currency exchange
EZL (formerly cashbee)	—	Convenience stores	Roughly equivalent to T-money. If you already have one, just use it

Beyond these, some tourist-pass products also include a transit card function. But those are combo passes for people visiting multiple paid attractions, not something to buy as a transit card. If getting around is your goal, you can rule them out.

T-money — Why It Remains the Default Choice

T-money's strength comes down to how little thinking it requires. Buy it at a convenience store, top it up at a convenience store, ride subways, buses, and taxis. Even if you move from Seoul to Busan or fly to Jeju, the card keeps working. At partner stores you can even pay for coffee with it.

What to watch out for: the 4,000-won physical card fee is not refundable. Even if you process a refund before going home, you only get back your loaded balance minus a fee — the card fee itself is excluded. In other words, think of the 4,000 won as the "cost of your ticket case."

Editor's note: Rather than going home with a leftover balance, it's faster to spend it down on drinks or snacks at a convenience store on your last day. No fees, no waiting. If you plan to visit Korea again, keep the card instead of tossing it.

How much should you load the first time?

This is the most searched number. Based on local experience, the following amounts are just right:

• Seoul, 3 days … 20,000–30,000 won
• Seoul, 5 days … 30,000–50,000 won
• Busan, 3–4 days … 20,000–40,000 won

If you run out, you can add funds at a convenience store in increments of 1,000 won. So don't load too much from the start. The more balance you have left over, the more of a hassle your departure day becomes.

Climate Card — When It Pays Off, and the Coverage Trap

This is Seoul City's flat-rate unlimited-ride pass. The physical card costs 3,000 won, and you add a pass for however many days you'll use. You can buy it at three chains: CU, GS25, and 7-Eleven.

Pass	Price
1-day pass	5,000 won
2-day pass	8,000 won
3-day pass	10,000 won
5-day pass	15,000 won
7-day pass	20,000 won

The 3-day pass is 10,000 won, the 7-day pass 20,000 won. The per-day cost drops as the duration increases, so if you ride 4–5+ times a day, it's a sure win. It pairs well with Seoul-focused itineraries like Myeongdong → Seongsu → Hongdae → Hangang.

But you can't ride these

The trap is coverage. The Climate Card excludes the Sinbundang Line, wide-area (gwangyeok) buses, airport buses, and routes outside Seoul. So if your itinerary includes Hwaseong Fortress in Suwon, Incheon, or Nami Island, this card alone won't get you there.

If you have even one day of going out to the suburbs, the practical combo is to carry a separate T-money card. Splitting the roles — "Climate Card within Seoul, T-money outside the city" — is less stressful than worrying about your balance every time.

From March 2026, you can buy it with a credit card

Purchases and top-ups, previously limited to cash or cards like KB Kookmin Card, became possible with overseas-issued Visa and Mastercard starting March 2026. However, an average fee of about 3.7% is added. On a 20,000-won 7-day pass that's only a few hundred won, but if you want to avoid fees, paying cash is the safe bet. 💳

WOWPASS — Convenience, at the Cost of Two Balances

WOWPASS combines T-money transit, prepaid payment, and cash exchange in one card. Insert Japanese yen (or other currency) into a dedicated machine and it's loaded as won, usable directly for card payments. Its biggest value: the time spent hunting for exchange offices disappears entirely.

However, there's a point where almost every first-time user stumbles. The spending balance and the transit balance are managed as separate accounts, and each must be topped up individually. Load 50,000 won for shopping, and you still can't ride the subway with that balance. You only find out when the turnstile rejects you — the classic mistake.

If you use it, transfer a few thousand won to the transit balance right when you exchange money. Get that one step out of the way first, and WOWPASS becomes the shortest route to "doing all of Korea with one card in your wallet."

Two questions decide your card

If you're torn, ask yourself in this order:

1. Will you leave Seoul on any day? → Yes / not sure: T-money. No: the Climate Card is a candidate.
2. Do you need to exchange cash? → Yes: WOWPASS. No: stick with your answer above.

For 4 days in Seoul with no suburbs and lots of moving around daily, a Climate Card 3-day pass (10,000 won) + 3,000-won physical card is simplest. For 3 days in Seoul + 1 day out to Incheon or Suwon, a T-money card at 4,000 won loaded with 20,000–30,000 won is the most carefree. If cash exchange is involved, consolidate with WOWPASS.

Card specifications can change, so before your trip, check the latest prices and covered routes on the official T-money website and the official Seoul Metropolitan Government website to be sure. ✈️

Summary

First time in Korea / multiple cities: T-money (physical card 4,000 won, card fee non-refundable). Riding all over Seoul only: Climate Card (physical card 3,000 won + passes from 5,000 won for 1 day to 20,000 won for 7 days, available at CU, GS25, and 7-Eleven). Want to bundle cash exchange: WOWPASS (but the spending and transit balances are separate).

For your first load: 20,000–30,000 won for 3 days in Seoul, 30,000–50,000 won for 5 days, and 20,000–40,000 won for 3–4 days in Busan. When you land at the airport, just decide one thing: "Will I leave Seoul on any day?" The rest narrows itself down to one card automatically.

FAQ

Can I get the T-money balance and card fee refunded?

Only the balance comes back. You're refunded your loaded balance minus a set fee, and the 4,000-won physical card fee is excluded. If only a small amount remains, spending it down at a convenience store is faster and loses you nothing.

Can I get to Incheon Airport or Suwon with the Climate Card?

No. The Sinbundang Line, wide-area buses, airport buses, and routes outside Seoul are excluded. If you plan to go to Incheon, Suwon, Nami Island, or the like, it's safest to have a separate T-money card ready.

Can I buy the Climate Card with a Japanese credit card?

Starting in March 2026, you can now purchase and top up with overseas-issued Visa and Mastercard cards. However, since an average fee of about 3.7% applies, buying with cash at a convenience store is the safer option if you want to avoid fees.
