The 30-second answer
Buy a T-money card at a participating convenience store or designated subway sales point, then load Korean won. KTO's 2026 visitor guide says overseas-issued cards are not accepted for ordinary T-money purchase or top-up, so carrying cash is the safest baseline. Use the card only where the T-money logo or current operator guidance confirms acceptance. Check the official refund channel and limits before leaving Korea; spending a small remaining balance at an affiliated shop may be simpler.
The practical rule is: do not rely on tapping an overseas bank card on an ordinary city-bus reader. KTO's 2026 guide directs visitors to a regular transportation card and notes only limited exceptions on selected services.
What T-money actually covers
| Where | Works? | Notes |
|---|---|---|
| Participating subway and metro systems | Check the T-money/operator logo | Tap in and out; transfer rules depend on the operator and timing |
| Participating city buses | Check the operator | Tap when boarding and, where instructed, when getting off |
| Participating taxis | Common | Confirm the T-money logo before the ride or keep another payment method |
| Affiliated stores | Check the T-money logo | Acceptance is not the same as every convenience-store branch |
| AREX All Stop train | Yes | The Express train needs a separate ticket |
| Intercity/KTX trains | No | Buy tickets separately (Korail app, station counters) |
Buying the card: step by step
- Look for the T-money logo at a convenience store or use a designated subway sales point. Ask "티머니 카드 주세요"; stock and supported card types can differ by branch.
- Pay for the card itself — this is the price of the plastic, not stored value. Designs and prices vary (standard cards vs character editions); the current price range is a verification item below.
- Top it up immediately (next section). A brand-new card holds zero balance.
- Check the terms for the exact card product. A basic unregistered card may not offer balance protection after loss, while tourist or app-linked products can have different registration rules.
Where to buy at the airport: convenience stores inside the arrivals area sell T-money before you reach the trains — buy it there so your very first tap is at the AREX gate. See the airport-to-Seoul guide.
Recharging: step by step
- Convenience store: hand the card and cash to the clerk and say "충전해 주세요" with the amount. Round numbers (10,000 / 20,000 won) keep it simple.
- Subway station machine: tap the English button, place the card on the reader tray, insert cash, and wait for the confirmation screen before lifting the card.
- Machines accept Korean won banknotes — this is where the cash from the ATM guide goes.
- Check your balance any time: every tap at a gate shows the remaining balance on the reader display, and machines have a balance-check menu.
Do not count on topping up with an overseas-issued card. Keep enough Korean won for the top-up and wait for the machine or clerk's confirmation before leaving.
Getting your balance refunded before you fly home
- For a small remaining balance, ask a participating T-money service location whether that card type and amount can be refunded. Do not assume every store provides refunds.
- For larger balances, refunds are handled at the T-money customer service center rather than a convenience store counter; check the official T-money site for the current location and hours.
- The card price itself is not refunded — only the loaded balance.
- Practical alternative: if an affiliated shop accepts the card, spend a small remaining balance before departure and avoid relying on a last-minute refund.
When things go wrong
- Gate shows an error / insufficient balance mid-journey: use the top-up machine inside the paid area or at the station and re-tap. Staff at the wide gate can let you through to the machines if you gesture at the card.
- You forgot to tap out of a bus: you may be charged as if you rode further, and you lose the transfer discount for the next leg. Nothing to fix afterwards — just tap out next time.
- Card stops working entirely: cards do occasionally fail. Buy a replacement and refund the dead card's balance at the T-money service center (convenience stores cannot read a dead card).
- You are leaving from the airport and the refund queue is long: spend the balance at an airport convenience store instead — the goal is not leaving money on the card, not the refund ritual itself.

FAQ
Can I use my foreign contactless credit card instead, like in London or Sydney?
Do not plan around it. KTO's 2026 guide says foreign-card taps are unavailable on ordinary subway and AREX readers and on ordinary bus readers, with limited exceptions on selected services. Use the payment method shown by the actual operator.
Is there a special tourist version of the card?
Tourist-branded passes and competing transport cards exist, with different coverage and refund rules. Compare the current route coverage against your itinerary before loading a large amount.
Can two people share one card?
No. Each rider taps their own card — the gate and the bus reader register one fare per tap, and transfer discounts are calculated per card.
Does the balance expire?
Expiry and dormancy rules belong to the terms for the exact product. If you plan to keep the card, verify those terms and retain the card number or receipt where the product supports recovery.
Can I top up or check the card with my phone?
Korean residents use phone-based T-money, but for visitors with foreign phones and cards, the physical card plus cash remains the dependable path. NFC top-up apps generally require Korean payment methods.
What about children's fares?
Discounted child/youth fares exist but require age registration on the card at purchase — ask the convenience store clerk when buying, with the child's passport available.
Information that can change
Card prices, refund ceilings, service fees, transit fares, and contactless acceptance can change. Use the official T-money and transit-operator pages below and keep cash for purchase or top-up.
- Card prices, refund ceilings, service fees, and large-balance refund locations can change; check the official T-money page before purchase or refund.
- Transit fares depend on operator, distance, transfer, and traveler type; use the current operator fare table.
- Do not assume a foreign bank card now works on every gate or bus reader. Keep enough T-money balance until the operator officially confirms otherwise.
- A purchase receipt and the card itself can be required for troubleshooting, so keep both until the end of the trip.
