T-money vs Climate Card: Which Transport Card to Buy in Korea
Both T-money and Climate Card are rechargeable transit cards that work on Seoul subways, buses, taxis and convenience stores throughout South Korea. The short answer: for most short-term foreign visitors, T-money is the simpler, more widely available choice. Climate Card is a monthly unlimited-ride pass launched in early 2024 that offers value only if you take at least 60 subway or bus trips per month within the Seoul metropolitan area. This guide explains what each card costs, where they work, how to buy and reload them, and which travellers actually benefit from the Climate Card subscription model.

What T-money is and how it works
T-money (티머니) is a stored-value card you tap on subway gates, bus card readers, and payment terminals in taxis and convenience stores across South Korea. You buy the physical card once for roughly 2,500-4,000 KRW, then load it with cash at any convenience store (GS25, CU, 7-Eleven, Emart24), subway station ticket machines, or using the T-money mobile app if your phone supports Korean NFC payment standards. Most foreign phones do not support the mobile T-money app, so visitors rely on the physical card.
When you tap in and out of the subway, the system deducts the distance-based fare automatically. The Seoul subway base fare is 1,550 KRW for the first 10 km, with small surcharges added for longer trips. Buses charge a similar base fare, and transfers between subway and bus within 30 minutes are free or discounted, which the card calculates for you. You do not select a fare or input a destination; the card reader knows where you tapped in and where you tapped out.
T-money works nationwide. The same card you use in Seoul works on the metro in Busan, Daegu, Daejeon and Gwangju, intercity buses, city buses in small towns, and many taxis. You can use it to pay at convenience stores and some vending machines, though international credit cards are widely accepted at those locations too. The card never expires. If you visit Korea again, you can reload and reuse the same card.
To reload, walk into any convenience store, hand the card to the cashier and say the amount you want to add in Korean won. They will tap it on their terminal and you pay cash or card. Machines at subway stations also reload T-money, with multilingual menus. A typical traveller loads 10,000-20,000 KRW at a time. Before you leave Korea, you can get a refund of your remaining balance at a convenience store. If the balance is under 20,000 KRW, a small processing fee of 500 KRW applies; balances over 20,000 KRW are refunded without fee. The card itself is not refundable.
What Climate Card is and who it is designed for
Climate Card (기후동행카드) is a monthly unlimited-ride public transport pass launched by the Seoul Metropolitan Government in January 2024 as an environmental and cost-saving initiative for daily commuters. You pay a flat monthly subscription, currently around 62,000-65,000 KRW depending on the tier, and ride Seoul subway lines and Seoul city buses as many times as you want within the calendar month. The stated goal is to encourage residents to choose public transit over private cars.
The card is sold as a physical card or a digital card loaded in a mobile app. Foreign visitors must use the physical version or the Seoul Metro app, but app setup requires a Korean phone number for verification in most cases. The physical Climate Card is available at select subway customer service centres, not convenience stores. You register the card, choose a subscription tier, and pay for the month. The unlimited rides activate immediately and expire on the last day of that calendar month, regardless of which day you purchased it.
The subscription covers only Seoul Metropolitan Rapid Transit lines (Seoul Metro lines 1-9, Shinbundang Line, and other Seoul-area light rail) and Seoul city buses operated by the city or affiliated companies. It does not cover intercity buses, taxis, the Airport Railroad Express (AREX) beyond certain stations, KTX trains, or any transport outside the Seoul metropolitan area. If you ride the subway from Seoul to Incheon or tap your card on a bus in Busan, the unlimited benefit does not apply and you are charged the standard fare, which the card deducts from a separate stored balance you must load, just like T-money.
Climate Card is a subscription model. If you do not cancel, it auto-renews each month. You must actively cancel through the app or service centre before the end of the month if you do not want to be charged for the next month. Refunds for unused days within the month are prorated, but processing takes time and requires returning the physical card or submitting a refund request in the app.
The breakeven point is roughly 60 rides per month at the base subway fare. A single ride costs 1,550 KRW with a transport card, so 60 rides cost 93,000 KRW. The Climate Card costs about 62,000-65,000 KRW, so daily commuters taking 2-3 trips a day save money. A tourist on a one-week trip takes maybe 14-20 subway and bus rides total, far below the breakeven threshold.
Cost comparison for short-term visitors
Most foreign visitors to Korea stay between 5 and 14 days. A typical Seoul itinerary involves 2-4 subway trips per day: morning trip to a palace or museum, midday move to a shopping district, evening trip to a restaurant neighbourhood, and a late return to the hotel. Add a few bus rides, and a week-long trip totals roughly 15-25 transit rides.
With T-money, each subway ride costs 1,550 KRW base fare, and most tourist destinations are within the 10 km base zone or add only 100-300 KRW in distance charges. Twenty rides at an average of 1,600 KRW each cost 32,000 KRW in fares, plus the 2,500-4,000 KRW card purchase, for a total of about 35,000-36,000 KRW. If you refund the remaining balance, your net cost is the fares paid plus the non-refundable card price.
With Climate Card, you pay roughly 62,000-65,000 KRW for the monthly pass, which gives you unlimited rides but only within Seoul city transit. If you stay seven days and take 20 rides, you paid 65,000 KRW for 20 rides that would have cost 32,000 KRW on T-money. You spent an extra 33,000 KRW, about 23 USD at the approximate 1,410 KRW per USD August 2026 exchange rate.
The only scenario where Climate Card saves a short-term visitor money is if you stay close to a full calendar month, never leave Seoul, and take an unusually high number of trips. For example, a digital nomad staying 28 days in Seoul, working from different cafes and co-working spaces, taking 3-4 subway trips per day, might hit 85-110 rides. At that volume, Climate Card saves money. But this is not the typical foreign tourist itinerary.
Additionally, if you plan day trips outside Seoul such as to Suwon Fortress, Sokcho, Busan, Jeonju or Gyeongju, the Climate Card offers no value at all on intercity buses, KTX trains or regional metro lines. T-money works everywhere. Even within Seoul, taxis accept T-money but not Climate Card unlimited benefits; you pay the metered fare even if you have an active Climate Card subscription.

Where to buy and reload each card
T-money cards are sold at convenience stores, subway station ticket machines and vending kiosks, tourist information centres, and the arrival hall at Incheon International Airport. Convenience stores are the easiest option because they are everywhere, open 24 hours, and staff are used to foreign customers buying T-money. Walk in, point to the T-money display rack near the counter, choose a card design, and pay. Character editions featuring cartoon mascots or K-pop groups cost about 4,000-5,000 KRW; plain cards cost 2,500-3,000 KRW.
Reloading T-money is equally simple. Hand your card to any convenience store cashier, say or gesture the amount you want to load, and pay. The transaction takes 10 seconds. Subway station ticket machines also reload T-money and offer English, Chinese and Japanese menus. Insert cash or use a credit card, tap your T-money on the reader, select the reload amount, and confirm. Machines accept 1,000, 5,000 and 10,000 KRW notes.
Climate Card is harder to acquire. The physical card is sold only at Seoul Metropolitan Rapid Transit customer service centres located inside major subway stations such as City Hall, Gangnam, Hongik University and Seoul Station. These centres have limited hours, typically 9:00-18:00 on weekdays, with reduced weekend hours or closures. You cannot buy a Climate Card at a convenience store or airport kiosk. The mobile app option requires downloading the Seoul Metropolitan Government or Seoul Metro official app, creating an account, and verifying a Korean mobile phone number, which most tourists do not have. Some travellers report using a foreign number, but the process is inconsistent.
Once you have a Climate Card, you must purchase the monthly subscription. This is done at the service centre when you buy the card, or through the mobile app. Payment is by credit card or Korean bank transfer. Unlike T-money, you cannot walk into a convenience store and ask staff to activate a Climate Card subscription; they have no way to process it. This makes Climate Card much less accessible for a newly arrived visitor who lands at Incheon at 10 PM and wants to get on the airport train immediately.
Refunds for T-money are processed at convenience stores. Hand the card to the cashier and ask for a refund. They will check the balance, subtract a 500 KRW fee if the balance is under 20,000 KRW, and give you cash. Climate Card refunds require returning the card to a service centre or submitting a cancellation and refund request in the app, with a wait time of several days to several weeks for the refund to process.
Coverage and acceptance outside Seoul
T-money is a national standard. The card works on every metro system in South Korea: Seoul, Busan, Daegu, Gwangju, Daejeon and the light rail networks in smaller cities. It works on intercity express buses, local city buses and most taxis that have a card reader installed, which is the majority in urban areas. In rural areas and small towns, some older taxis and small independent bus lines may not accept cards, but convenience stores in those areas still let you pay with T-money.
You can also use T-money for small purchases at convenience stores, coin-operated lockers at bus terminals and train stations, vending machines and some tourist-site ticket kiosks. The balance is deducted just like a prepaid debit card. Not all vendors accept it, but it is common enough that you can think of T-money as a general-purpose stored-value card, not just a transit pass.
Climate Card, by contrast, has strict geographic and modal limits. The unlimited-ride benefit applies only to Seoul Metropolitan Rapid Transit subway lines and Seoul city buses. If you tap your Climate Card on the Busan Metro, it does not recognise the Seoul subscription, and you are charged the standard Busan fare, deducted from a separate stored-value balance you must preload on the Climate Card. The card technically supports stored-value payments like T-money, but you must load that balance separately from the subscription fee.
Intercity buses operated by private companies do not honour the Climate Card unlimited plan. Taxis never do; even if the taxi is in Seoul and accepts card payment, you pay the metered fare. The same applies to the Airport Railroad Express: stations within Seoul may be covered under the subscription in some cases, but the express service to Incheon Airport is not, and you are charged the full AREX fare.
If your itinerary includes any travel outside Seoul, T-money is the practical choice. Even if you stay in Seoul the entire time, the convenience of buying and reloading T-money at any convenience store, and the ability to use it for small purchases, outweighs the theoretical savings of a Climate Card subscription that you will not come close to breaking even on.
Mobile app and digital card options
T-money offers a mobile app and digital card option for phones that support Korean NFC payment standards. Most foreign smartphones do not. The NFC chip in an iPhone purchased outside Korea, or an Android phone bought in the US, Europe or Australia, typically cannot emulate the Korea-specific transit card protocol. Some newer Android phones sold internationally have added support, but compatibility is inconsistent and requires installing the T-money app, creating an account, registering a Korean payment method, and enabling NFC permissions. For most tourists, the physical card is simpler and guaranteed to work.
Korean residents and long-term foreign residents with a Korean bank account and phone number use the mobile T-money card routinely. It works exactly like the physical card: tap your phone on the subway gate or bus reader. Reloading is done in the app via bank transfer. But setting this up during a one-week vacation is not practical, and if your phone does not support the protocol, it will not work at all no matter how much troubleshooting you attempt.
Climate Card similarly has a mobile version available in the Seoul Metro app or a standalone Climate Card app. Registration requires a phone number, and payment setup asks for a Korean credit card or bank account in many cases. Some travellers report successfully using foreign credit cards, but the process is not streamlined for tourists. The app interface is available in English, but error messages and customer service are mostly in Korean. If you are staying in Seoul for a month or longer, working or studying, it may be worth the effort to set up the app. For a short visit, the friction is not justified.
Neither app is necessary if you use a physical card. The apps offer features like balance checking, transaction history and automatic reloads, which are conveniences, not requirements. A foreign visitor can complete an entire trip using a physical T-money card loaded at convenience stores and never install an app.
Which card to choose for your trip
Choose T-money if your trip is shorter than three weeks, if you plan to visit any city outside Seoul, if you want the simplest purchase and reload process, or if you want to use the card for convenience store purchases and taxis. This applies to the large majority of foreign tourists. T-money is more flexible, easier to acquire, and costs significantly less for typical itineraries.
Choose Climate Card only if you meet all of the following: you are staying in Seoul for at least 25-30 days, you will remain within Seoul city limits the entire time, you will take at least 60 subway or bus rides during the month, you are comfortable navigating a Korean-language registration and refund process, and you are willing to go to a specific subway service centre during business hours to buy the card and potentially return it for a refund. This scenario fits long-term travellers, digital nomads staying a month, or foreigners on extended work or study assignments, not typical vacation visitors.
If you are unsure, default to T-money. The financial risk is low: you spend 3,000 KRW on the card and load only as much as you need. If you underestimate, you reload at any convenience store in two minutes. If you overestimate, you get a refund minus a small fee. Climate Card locks you into a 65,000 KRW monthly fee with a more complex refund process and no flexibility for trips outside Seoul.
Some visitors ask whether they can buy both and use Climate Card for Seoul days and T-money for day trips. This is technically possible but adds unnecessary complexity and cost. You still pay for the full Climate Card month even if you only use it half the days. The savings are marginal at best, and you have to carry and manage two cards. The simpler strategy is to use T-money for everything and accept that you pay per ride, which is what the system is designed for.
Remember that Google Maps does not provide walking or transit directions inside South Korea due to mapping data export restrictions. Use Naver Map or KakaoMap, both of which have English interfaces, to plan routes and check subway transfers. Both apps show real-time subway and bus arrivals and calculate fares and transfer discounts automatically when you input your origin and destination.

Practical tips
Frequently asked questions
Before you go
For nearly all foreign visitors on a typical one- to two-week trip to Korea, T-money is the clear choice: cheaper, easier to buy and reload, accepted nationwide, and flexible enough to use at convenience stores and in taxis. Climate Card is a commuter subscription designed for residents who ride Seoul transit daily; tourists rarely take enough trips within the calendar month to justify the upfront cost or the hassle of purchasing and refunding it. Unless you are staying in Seoul for close to a full month and never leaving the city, buy a T-money card at a convenience store, load it as you go, and get on with exploring the country.
