The T-Money card is the single most useful item you can have in Seoul — and this complete T-Money card guide tells you everything you need to know before you arrive.
This T-Money card guide covers where to buy your T-Money card, how to charge it, how to use it on every form of transport, and insider tips that most visitors only learn after their first day in Seoul.
What Is the T-Money Card?
The T-Money card is a rechargeable prepaid transportation card that works across Seoul’s entire public transport network — subways, buses, taxis, and even some convenience stores.
Think of the T-Money card as an Oyster card (London) or Suica card (Tokyo) — a single card that handles all your transport needs without buying individual tickets every time.
The T-Money card saves money too. Every ride paid with a T-Money card costs ₩100–₩150 less than a single-use ticket. For a week of daily travel, your T-Money card saves roughly ₩1,000–₩2,000.
Before using your T-Money card on Seoul’s subway, read our complete Seoul Subway Guide to understand the network.
Where to Buy a T-Money Card
Buying a T-Money card is extremely easy. T-Money cards are available at every convenience store in Korea — CU, GS25, 7-Eleven, and Ministop all sell T-Money cards at the counter.
T-Money card price: ₩2,500–₩4,000 for the card itself (blank — no credit loaded)
At the airport: The convenience store in Incheon Airport arrivals sells T-Money cards — buy yours immediately after landing. Read our Incheon Airport to Seoul Guide for full arrival logistics.
Special T-Money cards: Kakao Friends, BTS, and character-themed T-Money cards are available at convenience stores and tourist shops. These make great souvenirs and function identically to standard T-Money cards.
How to Charge Your T-Money Card
Charging your T-Money card takes about 30 seconds. There are two easy ways.
At a convenience store: Hand your T-Money card to the cashier and say “T-Money card charge, [amount] won please” or simply show the card and hold up fingers indicating how much you want to add. Minimum charge is usually ₩1,000.
At subway station machines: Every Seoul subway station has T-Money card charging machines near the entrance. Insert cash, tap your T-Money card, select the amount, and done.
How much to charge: Load ₩20,000–₩30,000 for a week of regular use. Each subway ride costs ₩1,400–₩1,800 with a T-Money card.
How to Use Your T-Money Card
Using your T-Money card is simple — tap in, tap out.
On the subway:
- Tap your T-Money card on the yellow reader at the entrance turnstile
- Ride to your destination
- Tap your T-Money card again at the exit turnstile
- The fare is automatically deducted based on distance
On buses:
- Tap your T-Money card on the reader when boarding
- Tap again when exiting (important — skipping the exit tap can result in maximum fare charges)
In taxis: Tell the driver you want to pay by T-Money card before the ride ends. Tap your T-Money card on the reader near the driver when paying.
At convenience stores: Some CU and GS25 locations accept T-Money card payments for purchases. Look for the T-Money card logo at the register. Read our Korean Convenience Store Guide for more on convenience store payments.
T-Money Card Transfer Discount
One of the best T-Money card features is the transfer discount.
When transferring between subway lines or from subway to bus (or vice versa) within 30 minutes, your T-Money card automatically applies a transfer discount — you pay only the distance difference rather than a full new fare.
This T-Money card transfer discount can save significant money on longer journeys involving multiple transport types. It only works with a T-Money card — single-use tickets don’t get this discount.
Checking Your T-Money Card Balance
Checking your T-Money card balance is easy.
At subway turnstiles: Your T-Money card balance appears on the reader screen every time you tap in or tap out.
At convenience stores: Ask the cashier to check your T-Money card balance — they can see it instantly on their register.
At subway machines: Insert your T-Money card into any T-Money card charging machine to see your current balance.
Minimum balance warning: If your T-Money card balance drops below ₩500, you may not be able to complete a trip. Keep your T-Money card charged to avoid being stranded.
T-Money Card Refund
When leaving Korea, you can get your remaining T-Money card balance refunded.
At convenience stores: Refunds of up to ₩20,000 are available at any CU, GS25, or 7-Eleven. A small fee of ₩500 is deducted.
At subway station service centers: Larger refunds are available at staffed service centers in major subway stations.
Keep your T-Money card: If you plan to return to Korea, keep your T-Money card. It never expires and saves you ₩2,500–₩4,000 on your next visit.

T-Money Card Tips for Foreigners
Buy your T-Money card at the airport. Don’t navigate Seoul’s subway on your first day without a T-Money card — buy one immediately at the Incheon Airport convenience store.
Always tap out. Forgetting to tap your T-Money card on exit results in maximum distance fare being charged. Always tap out.
Keep ₩10,000+ loaded. Running out of T-Money card credit mid-journey is easily avoidable. Check your balance regularly.
The T-Money card works outside Seoul. Your T-Money card works in Busan, Daegu, Incheon, and most other Korean cities — useful if you’re following our Busan vs Seoul Guide and visiting both cities.
