Buy the card and load it separately
The Korea Tourism Organization's card guide lists convenience stores and Seoul subway information centers on Lines 1–8 as purchase locations. Its August 2026 guide gives a general card price of ₩3,000–5,000. The card price and the balance you add are separate costs.
At the counter, ask for a regular rechargeable T-money card, then specify the amount to load. Check the balance before walking away. Bring Korean won as a fallback instead of assuming a foreign bank card will fund every type of transit product.
Tap out of the bus as well as the subway
Seoul's bus rules require an exit tap to receive the transfer discount. Use the same card for the next leg. Reboarding the same bus or route does not qualify.
For example, a daytime bus exit at 14:00 followed by a different eligible service at 14:20 is inside the transfer window; 14:35 is outside it. Keep the card ready before reaching the exit reader rather than searching for it after the doors open.
Do not confuse three payment products
| What you are buying | What to check |
|---|---|
| Regular T-money | Card cost, loaded balance and the top-up method accepted at that location |
| Climate Card short-term pass | Coverage and validity for the journeys you intend to make |
| Single-journey subway ticket | Destination and the ticket machine's payment options |
Seoul's March 2026 payment announcement covers international-card purchases of short-term Climate Cards and single-journey tickets. It is not an announcement that any foreign bank card can be tapped directly at a gate, or that every regular T-money top-up accepts it.
Avoid loading more than you expect to spend
Top up again when needed instead of loading your entire shopping budget onto a transit card. For refunds, KTO directs T-money balances above ₩50,000 to Tmoney Town near Seoul Station; check the operator's current fee and counter conditions before making a special trip. If your departure is early, arrange any refund beforehand rather than leaving it until the airport transfer.
