Public transport in South Korea is simple to use, but it is even easier (and sometimes cheaper) with a T-money card (or the Seoul Climate Card).
From the buses of Busan to the Seoul Subway, the best way to use public transport across South Korea hassle-free is by using a T-money card or similar transportation card.

Getting around South Korea with a T-money card
The main ways to get around South Korea are by subway, bus, train or taxi / driving.
Whilst buses and trains operate in all towns and cities, the South Korea Metro / Subway system can only be used in bigger cities – Seoul, Busan, Incheon, Daegu, Gwangju, Daejeon and Gyeonggi-do.
T-money cards are accepted on most metropolitan local bus services too and some airport shuttles.
Most importantly, if you are arriving into Seoul Incheon International Airport for the first time, you can use the T-Money card on the Airport Limousine buses and the non Express Airport AREX train) – but not the Climate Card. So consider buying a T-Money card from Klook >

What are T-money cards in Korea?
T-money cards are top-up payment and transit cards that you can use on public transport and in taxis, as well as convenience stores, telephone booths and many electronic storage lockers.
To use a T-money card in Korea, you can purchase one from a convenience store like 7-Eleven or station and top it up using cash (KRW only) or a debit card. Alternatively, there are T-Money vending machines available at Incheon International Airport.

How much is a T-money card?
In South Korea, T-money cards initially cost 5,000 Won but last indefinitely and are very convenient to hop on and off public transport in Seoul and South Korea.
A minimum top-up starting balance starts from 1,000 Won on top of your purchase price.

As well as convenience stores, T-money cards can be used to purchase items in shops like Daiso, Starbucks, Dunkin Donuts, McDonalds and Lotteria (but alas not in Olive Young!).
Look out for the T-money logo on display in shops that accept it as a payment method.
Please note only Korean Won can be used to top up a Korean T-money card.

T -Money Refunds
The refund process varies a little depending on the store / city.
For instance, in Seoul, T-money refunds of up to 30,000 Won can be completed at CU, MiniStop and eMart 24, and up to 25,000 Won at 7-Eleven and GS25.
At Subway stations, up to 50,000 Won refunds can be processed. For anything over 50,000 KRW, you would need to visit a bank, T-money head office or consult the T Money mobile app – pay.tmoney.co.kr.
Remember that the original T-money card payment (usually 5,000 Won) is non-refundable – but you get to keep it as a unique souvenir of South Korea. Plus you can use it on your return trip as T-money cards never expire.

What are the benefits on T-money cards?
The main advantage of T-money cards is not having to worry about having cash on you to pay for fares (plus some South Korea buses don’t accept cash). Those buses that do – like the airport limousine buses often don’t give change if you only have big notes.
In addition, for overseas travellers, it is very easy to buy and top up a T-money card as opposed to having to consider opening additional bank accounts or worry about whether your overseas debit card will work everywhere.
In our experience, our UK ATM / debit cards often get rejected so it is handy to have a guaranteed form of payment.
T Money cards also enable payment at both on and offline stores, and T-money cards can be used by all ages (although parents may need to register children under the age of 18 to make use of transport discounts).
In addition, some of the transport fares are marginally cheaper if you use aT-money card as opposed to cash.
Plus the Korea Tour T-money card offers discounts at some tourist attractions like 10% off Seoul Sky or 50% off hanbok rental at Cham Hanbok in Jongno, Seoul.

Safety
T-money cards are easy and safe to use – the other advantage they have over cash is that you register your card online, you can report the loss online and cancel via the T-money app, but you must register it first.

Personalised T-money cards
A big theme / trend in South Korea is to personalise your T-money card or transport payment cards with your own stickers or designs.
For instance in Busan, we were given fairly blank Korean Tour Cards and we blinged them (some would say ‘upgraded’!) with Kakao Friends character stickers like Choonsik the cat or fun transport stickers.

Personal experience using T-money cards
We were lucky enough to win a Korea Tour Card / T-money card by the Korean Tourism Organisation at a K-Pop concert in Busan.
We found using the T-money card so easy and quick and it transformed our public transport trips.
We didn’t have to try and fiddle around finding loose change or research how much public buses cost in advance to ensure we had the correct change. Did you know most buses in South Korea that accept cash don’t provide any change either?
We used our T-money cards in both Busan and Seoul and never had any issues – we regularly topped them up at transport card terminals in Subway stations and never looked back.
All in all, T-money cards are incredibly easy to use and top-up and we’d highly recommend buying one (and covering it in crazy stickers too!)

Can you use your T-money card to pay in convenience stores?
Yes, most big South Korean convenience stores like CU shops, 7-Eleven and GS25 accept topped up T-money cards as payment – although you must ensure you have sufficient credit to cover your purchases.

Is there a T-money app in South Korea?
There are supporting Korean apps but T-money is a physical digital payment card – if you want an e-payment app on your phone, consider Line Friends or Kakao.
T-money also has a website / app where you can register your details but this is not compulsory (and not something we did).

Seoul Climate Card
Introduced in 2024, the Seoul Climate Card is different from the T-Money card as it is an unlimited public transport pass for Seoul only.
The Climate Card can be used for unlimited travel for 30 days on the Seoul Metro, buses (not airport limousine or Intercity) and Ttareungi (Seoul Bikes you can hire).
There are some exceptions for instance you cannot use it on the AREX from Incheon Airport into Seoul BUT you can use it to go from Seoul back to Incheon Airport – nor can you use it on the Sinbundang Line / Dynamic Express Line.
The Seoul Climate Card price is 65,000 Won for a 30 day pass that includes Seoul Subway, buses and the Ttareungi / bikes – the Climate card price is correct as of April 2025.
So the full Climate Card costs around £35, $46 USD or 40 Euros.
For a 30 day Seoul Climate Card without bike usage, the price drops to 62,000 Won.
You can also buy the following shorter duration Seoul Climate Card passes (all excluding bicycle rental):
1 day – 5,000 Won
2 day – 8,000 Won
3 day – 10,000 Won
5 day – 15,000 Won
7 day – 20,000 Won
Like the T-Money card, you must tap on and off the Climate card when using buses and trains. For bicycle hire, download the T Money Go App, register you card then go the bike tab – you can use bicycles for up to 2 hours at a time.
Climate Cards can be purchased from Seoul Tourist Information Centers, customer safety kiosks at selected subway stations on lines 1 to 8 and some convenience stores near Subway stations. Top up kiosks can be found in Seoul Metro stations, Line 9, Ui-Sinseol Line and the Sillim line.

Discover Seoul Pass / Visit Busan Pass (for visitors)
Exclusive to foreign travellers visiting South Korea from overseas, both Seoul and Busan offer special ‘free-pass style’ tourist passes that allow tourists use of major attractions, all for one low price over a certain timeframe.
With these Discover Seoul Passes or Visit Busan Passes, users can enjoy numerous discounts and ticket attractions as well as free transport options like hop-on hop-off bus passes or airport shuttles.
If you use the physical Discover Seoul Pass or Visit Busan Pass cards (rather than mobile app), you can then use the card as a T-money card. Both cards have multiple pick up points including the main airports.
We’ve used both a Visit Busan Pass and Discover Seoul Pass on separate occasions and on average, saved around 70% on average on top attractions.
On both passes, we visited / completed 7 or 8 activities and tours including Lotte World Seoul and Lotte Adventure World in Busan.
As of April 2025, the Discover Seoul and Discover Busan pass prices are as follows:
Discover Seoul Pass costs:
- 24 hours for 50,000 Won
- 48 hours for 70,000 Won
- 72 hours for 90,000 Won
- 120 hours for 130,000 Won
