In Korea, especially in large cities, people get around using public transportation. The subway is one of the most common and efficient forms of public transportation. For convenience, we recommend purchasing a rechargeable T-money card, but there is now a new “unlimited” option to consider as well. Let’s take a look at the latest updates on Korea’s public transportation cards.

What is a T-money card?
Subway lines in Korea are highly efficient and affordable. As of the latest updates, the base fare for the Seoul subway starts at 1,550 won (roughly 1.10 USD) when using a transportation card, following recent fare hikes to support system maintenance.
Single tickets can still be purchased from machines at each station, but the most convenient way to travel is with a T-money card. You can purchase this rechargeable card at convenience stores such as GS25, CU, and 7-Eleven for approximately 2,500 to 5,000 won (depending on the design).
This prepaid card can be recharged at any metro station or convenience store. It is particularly convenient for “transfers”: if you switch from the metro to a bus (or vice versa) within 30 minutes, you receive a significant discount, often only paying a small distance-based surcharge rather than a new base fare. Because it uses RFID technology, you must tap your card on the electronic sensors both when entering and exiting the subway or bus to ensure the correct fare is calculated.
The “Climate card” for unlimited travel
If you are planning to stay in Seoul for a longer period or plan to travel multiple times a day, the standard T-money card might not be your cheapest option anymore. In early 2024, Seoul introduced the Climate Card (기후동행카드).
As detailed in this article, the Climate card is an eco-friendly pass that allows unlimited use of Seoul’s subways and buses for a fixed monthly price (starting at 62,000 won). It is an excellent choice for students or residents who commute daily. While the T-money card is better for occasional travelers or those visiting multiple cities like Busan and Daegu, the Climate Card is the king of convenience for Seoul locals.
Where else can you use T-money?
The T-money card is more than just a transit pass. It acts as a prepaid debit card in most convenience stores, certain bakeries (like Paris Baguette), and even some taxis.
If you have a Korean bank account and a Residence Card (ARC), you can link your bank card to function as a “post-paid” T-money card, where expenses are debited once a month. However, for tourists and short-term visitors, the rechargeable “pre-paid” version remains the standard.

Tips for navigating the subway
The South Korean subway system is world-class, but the scale varies by city. The Seoul subway system is massive, featuring 23 lines and over 700 stations that can take you almost anywhere in the metropolitan area. In contrast, Busan offers a more streamlined experience with 6 lines (4 main metro lines plus the Donghae Line and Gimhae Light Rail) serving 158 stations.
Here are a few modern tips for your journey:
- Avoid rush hour: To stay comfortable, avoid traveling between 7:30 – 9:30 a.m. and 6:00 – 7:30 p.m. In Seoul: Be extra wary of Line 2 (the green circle line) and Line 9 (the gold express line). In Busan: Line 1 (orange) and Line 2 (green) are the busiest, especially around Seomyeon Station, where the two lines intersect.
- Language is no barrier: Don’t worry about getting lost; all announcements, digital screens, and physical signs are available in Korean, English, Japanese, and Chinese.
- Essential apps: Download Naver Maps or KakaoMap. While “Subway Korea” is helpful for simple routing, Naver Maps provides real-time data on exactly how crowded each subway car is and precisely where to stand on the platform for the fastest transfer.
- Traveling between cities: If you want to travel between Seoul and Busan (or beyond), use the KTX or SRT express trains.
- In Seoul: Trains depart primarily from Seoul Station (서울역) and Yongsan Station (용산역).
- In Busan: The main hub is Busan Station (부산역).
- Bonus Tip: From Cheongnyangni Station (청량리역) in Seoul, you can take the KTX-Eum to reach Pyeongchang or the east coast much faster.
We hope that you’re ready to navigate Korea’s public transportation cards. With your T-money or Climate Card in hand, the entire country is now just a tap away.
