How to Use a T-money Card Like a Local
T-money is the rechargeable transit card used across Seoul buses, subways, taxis, and convenience stores. It saves you time, gives you a small discount per ride, and is the single most useful thing you can get on day one of your trip.
What Is T-money?
T-money is South Korea's rechargeable transit card, accepted on buses, subways, taxis, and even at many convenience stores. It is the single most useful item you can get on day one of your Seoul trip.
Unlike buying individual subway tickets each time, T-money gives you a small discount per ride (₩100–₩150) and lets you transfer between bus and subway without paying full fare again.
How to Get One
T-money cards are sold at:
- Convenience stores — GS25, CU, 7-Eleven, and Ministop (look for the T-money logo near the register)
- Seoul Station information and ticket counters
- Incheon Airport — Exits 5 and 10 of the arrivals hall
Card cost: ₩2,500–₩4,000 depending on the design (there are many collectible versions)
How to Recharge
Add credit at:
- Any convenience store cashier — just hand over the card and say the amount
- Subway station ticket machines — select "Recharge T-money" on the screen
- The T-money app (for NFC-compatible smartphones)
Recommended first top-up: ₩30,000–₩50,000 if you plan to use public transport daily
Where You Can Use It
| Where | Details |
|---|---|
| Seoul Metro | All lines — tap in and tap out at the gate |
| City Buses | Seoul, Incheon, and most of Gyeonggi Province |

Transfer Discounts
One of T-money's best features is the transfer discount. If you transfer between a bus and the subway (or between two buses) within 30 minutes, the second ride is discounted. Over the course of a week, this can save several thousand won.
The discount applies automatically when you tap in — no action needed.
Common Mistakes Foreigners Make
Not checking the balance before boarding. If your card runs out mid-trip on the subway, you must settle the fare at the exit gate — which causes delays during rush hour.
Forgetting to tap out on the subway. You must tap both when entering and when exiting. Skipping the exit tap causes a fare error and may temporarily freeze your card.
Assuming it works everywhere. T-money is a transit card, not a general payment card. It does not work at most restaurants, on KTX (high-speed trains), or at most tourist attractions.
Over-topping up. Refunds are available at convenience stores, but there is a ₩500 fee per refund and a ₩20,000 maximum per transaction. Try not to load more than you need.
Returning or Keeping the Card
If you have remaining balance when leaving, you can get a refund at any convenience store (minus the ₩500 service fee).
Alternatively, keep the card — it works every time you return to Korea, and some limited-edition T-money cards make genuinely nice souvenirs.
