If you are planning a trip to Seoul, the very first thing you need is the T-money Card Korea. Without this, traveling in Korea is very difficult.
The T-money Card Korea is not just a subway ticket; it is your “Key to the City.” However, many tourists make mistakes with charging and refunding.
In this guide, I will explain everything about the T-money Card Korea, including where to buy it and how to get your money back.
What is the T-money Card Korea? 🤔
The T-money Card Korea is a rechargeable smart card used for public transport. But it does more than that. It is the most popular payment method for travelers.
With a T-money Card Korea, you can easily pay for:
- Transport: Subway, Bus, Taxi, and AREX (All-Stop Train).
- Shopping: Convenience stores (CU, GS25, 7-Eleven), Vending machines.
- Lockers: Subway coin lockers.
Step 1: Where to Buy? (Cute vs. Basic)
You can buy the T-money Card Korea at Convenience Stores or Subway Stations. The price is usually 3,000 KRW to 5,000 KRW (card only, no balance).

💡 Editor’s Pick: Go to a Convenience Store!
Subway vending machines only sell boring, basic cards. If you go to a convenience store (CU, GS25), you can find T-money cards with K-Pop idols (BTS, Seventeen) or cute characters (Kakao Friends, Line Friends). They make great souvenirs!
Step 2: How to Top Up (⚠️ CASH ONLY!)
This is the most important part of the T-money Card Korea guide. Please read carefully.
You CANNOT use a Credit Card to top up T-money.
Whether you are at a convenience store or a subway ticket machine, you must use Korean Won Cash (KRW). Many tourists bring only credit cards and panic at the station. Always carry at least 20,000 KRW in cash for transport.
Step 3: How to Get a Refund 💸
Leaving Korea? Don’t take the balance with you. You can get a refund easily.
- Balance under 20,000 KRW: Go to any convenience store (CU, GS25). They will give you the cash back instantly (minus a 500 KRW service fee).
- Balance over 20,000 KRW: Convenience stores cannot handle this. You must visit the “T-money Town” or specific subway service centers, which is complicated.
💡 Pro Tip: Try to use up your balance at the convenience store at the airport (buying snacks or water) instead of getting a refund. It is much easier.
