WOWPASS vs T-money vs Climate Card: Which Transit Card to Get

When does the Climate Card pay for itself?

At just over two fares a day on a 7-day pass, and more than three on a 1-day pass. The arithmetic is simple because a Seoul subway ride on a card starts at 1,550 won.

A 7-day pass costs 20,000 won and the card 3,000 won, so a week costs 23,000 won, or about 3,300 won a day. That is roughly two rides. A 1-day pass is 5,000 won, which is three rides and change, and on the first day the 3,000 won card pushes that past five. So the longer pass is the good deal, and the 1-day pass rarely is.

Two rules decide whether that works in practice. Days are calendar days that start on the day you charge the card, so a 1-day pass bought at 10pm expires with that night's last train. And a subway-to-bus change inside the transfer window already stays on one fare with T-money, so count journeys rather than vehicles when you estimate. The transfer rule is set out in the Seoul subway fares guide.

Buying the pass no longer needs cash. Since 17 March 2026, new machines at stations on Lines 1 to 8 sell Climate Card passes to Visa and Mastercard holders, with Seoul quoting an average fee of about 3.7%.

What changes on 1 October 2026?

The pass shrinks to Seoul. From 1 October, Seoul says short-term passes are valid within Seoul and on trips ending at Incheon International Airport, and Gimpo, Goyang, Gwacheon, Guri, Seongnam, Hanam and Namyangju drop out of the service area. Gimpo Airport Station, which is in Seoul, stays in.

The pass does not cover the Sinbundang Line, GTX, red Gwangyeok express buses or airport buses, and it does not include Ttareungyi bikes or the Hangang Bus. If you ride out of the area on the subway, station staff charge the fare from the station where you boarded.

The other change is one you can ignore. The 30-day Climate Card stopped taking recharges on 31 August 2026 and its replacement, the Climate Pass, is for Seoul residents only. The 1, 2, 3, 5 and 7-day tourist passes carry on.

Is WOWPASS worth the 6,000 won?

Only for the shopping side. On a bus or subway, WOWPASS works as a T-money card, and fares come out of its T-money balance rather than its main balance. You fill that transit balance with cash at the same machines as any T-money card, or by moving money across in the WOWPASS app. Money moves one way only: T-money balance cannot go back to the WOWPASS side.

What the fee buys is the main balance, a prepaid card you load with cash in 16 currencies at WOWPASS machines or with international cards in the app, and spend at shops that take cards. WOWPASS says it does not charge for currency exchange. Getting leftover money back costs 1,000 won per withdrawal of up to 100,000 won, and the 6,000 won membership fee is not refunded.

Our pick is WOWPASS for travellers carrying cash they want to change on arrival, or who expect their home card to be declined. For everyone else, a 3,000 to 5,000 won T-money card and a credit card do the same job. The wider question of cards and cash is covered in how to pay in Korea.

Can you skip the card and use your phone?

On an iPhone, yes. Since March 2026, a Foreigner option in the Tmoney app lets visitors top up a T-money card in Apple Wallet with a non-Korean Mastercard, American Express or UnionPay card, according to the Korea JoongAng Daily. Visa was not supported at the time of that report, so Visa holders still need a physical card.

If you are buying a data plan anyway, the card can come free: LG U+ includes a T-money card, collected at the airport, with eSIM plans of three days or more.

How do you get money back at the end?

At a convenience store for small T-money balances. Refunds carry a 500 won fee and the price of the card is not returned. The Korea Tourism Organization says refunds over 50,000 won have to be made at Tmoney Town near Seoul Station Exit 10.

A Climate Card pass refunds what you charged minus what you used and a 500 won fee, and the refund has to be requested before the pass ends. WOWPASS balances come back as won from a WOWPASS machine.

The cheapest end to a trip is to run the balance down: load small amounts in the last days, and spend what is left on a convenience store purchase, which T-money cards also pay for. For the rest of the planning, start with the South Korea travel guide.
