T-money Card: Buying, Topping Up, and Getting Your Money Back

T-money Card: Buying, Topping Up, and Getting Your Money Back

Byjamesju

Quick Answer

A T-money card costs ₩2,500–4,000 and works on subways, buses, taxis and in convenience stores nationwide. The card fee itself is never refundable, but leftover balance is. Refunds under ₩20,000–30,000 are handled at convenience stores for a ₩500 fee; larger balances need a subway service centre. Online refunds charge 4% on anything above ₩20,000 — a fee most English guides do not mention.

The Full Answer

Almost every guide to Korea tells you to buy a T-money card. Very few explain what happens at the end of the trip, when you are standing at Incheon Airport with ₩13,400 sitting on a plastic card you will never use again.

That end-of-trip moment is where the details matter, and it is where English-language guides thin out. They agree on the basics — buy at a convenience store, tap in and out, ₩500 refund fee — and then stop. The Korean-language sources go further, and some of what they add changes what you should do.

I compared the official T-money refund guidance with the top English guides in July 2026, and checked the regional transfer rules published by each local authority. Three things appear consistently in Korean sources and in none of the English ones: a percentage fee on online refunds, convenience store limits that differ between branches, and card types that are excluded from ATM refunds entirely.

Buying and Loading

  • Where: any CU, GS25, 7-Eleven, Emart24 or Ministop, plus subway station machines
  • Card price: ₩2,500–4,000 depending on the design. Not refundable
  • Loading: cash at convenience stores and station machines. Some machines take cards, many do not
  • Discount: card fare is cheaper than cash fare on buses and subways, and cash fares do not qualify for free transfers

There are several competing cards — T-money, Cashbee, Hanaro — and for a traveller they are functionally the same. Take whichever the shop has.

Local tip — Load in ₩10,000 increments rather than topping up to an exact amount. Refund fees are flat at ₩500 in convenience stores, so several small refunds cost more than one larger one, and you cannot get a partial refund of a partial balance.

Getting Your Balance Back

This is the part worth reading before your last day.

Balance Where Fee
Under ₩20,000–30,000 Convenience store ₩500
Up to ₩50,000 Subway station service centre (고객센터) ₩500
Above ₩50,000 Korean bank account required —
Any amount Online (T-money site / PAYCO) 4% above ₩20,000

At a convenience store, hand the card to the cashier and say 환불 (hwan-bul). They will refund the balance in cash minus ₩500. At a station service centre you may be asked for your passport.

Local tip — The convenience store limit is usually quoted as ₩20,000 in English guides, but Korean sources list it as ₩20,000 or ₩30,000 depending on the branch. If a cashier refuses a ₩25,000 refund, that is not an error — try a different chain rather than assuming the card is faulty.

Local tip — Online refunds are convenient but carry a 4% fee on the portion above ₩20,000, and require a Korean bank account. For a departing visitor the offline route is almost always better, even with the ₩500 charge.

Local tip — Mobile T-money, Homeplus cards, and basic-tier cards cannot be refunded at ATMs. English guides usually treat all transit cards as interchangeable. They are not, and finding out at 05:00 in an airport is a bad time.

Before You Fly Out

The refund windows close earlier than people expect.

  • Do it before airport security. Once you are airside, the counters are behind you
  • Convenience stores inside the terminal can refund small balances, but queues at departure peaks are long
  • If your balance is above ₩50,000 and you have no Korean bank account, the practical answer is to spend it down — the AREX train to the airport, a taxi, convenience store snacks, or topping up a travelling companion’s card

Regional Differences

T-money works nationwide, but the local rules around it do not.

Region Card Transfer window
Seoul metro area T-money / Cashbee 30 min (60 min after 21:00)
Jeju Same cards accepted 40 min, and the same route number does not qualify
Busan Cashbee most common locally 30 min

Local tip — The transfer window is not the same across the country. Jeju allows 40 minutes where Seoul allows 30, and Jeju excludes transfers onto the same route number entirely. Guides written about Seoul are routinely applied to the whole country, and that is where the extra fares come from — see the Jeju bus rules.

Passes Worth Knowing About

Seoul sells unlimited-ride passes aimed at heavy users. Whether one beats pay-as-you-go depends almost entirely on how many journeys you make per day.

  • Pay-as-you-go suits most visitors making three or four trips a day
  • Unlimited passes start to win at higher volumes, or when you are using buses heavily alongside the subway

Local tip — Do the arithmetic before buying a pass. At ₩1,550 a ride, a daily pass needs roughly five or more journeys to break even, and most sightseeing days involve three or four. Passes are marketed hard at tourists and are frequently the more expensive option.

What You Need to Know

  • The card fee is gone for good. ₩2,500–4,000 buys the card, not credit. Only the loaded balance is refundable.

  • Refund limits vary by branch, not just by chain. Korean sources list ₩20,000 or ₩30,000 for convenience stores. Treat ₩20,000 as the safe assumption.

  • Online refunds cost 4% above ₩20,000 and need a Korean bank account. Not practical for most visitors.

  • Not all transit cards refund the same way. Mobile T-money and some retailer-branded cards are excluded from ATM refunds.

  • You keep the physical card. Refunding the balance does not surrender the card, so you can keep it for a future trip and reload it then.

  • Transfer rules vary by region. Jeju’s 40-minute window and same-route exclusion differ from Seoul’s.

  • Unlimited passes rarely pay off for sightseeing. Three or four rides a day usually favours pay-as-you-go.

Practical Tips

  1. Buy the card on arrival, not in advance. They are sold at every convenience store and airport counter, and pre-ordering online adds no benefit.

  2. Load ₩10,000 at a time. Easier to spend down, and avoids being stuck above a refund threshold.

  3. Ask for 환불 (hwan-bul). One word is enough at any convenience store counter.

  4. Carry your passport on refund day if your balance is over ₩20,000 — station service centres may ask for it.

  5. Spend down rather than refund if you are above ₩50,000. The bank account requirement makes refunds impractical for short-term visitors.

  6. Check local transfer rules when you leave Seoul. Jeju and Busan differ.

  7. Remember the tap-out penalty. Since March 2026 a missed tap-out adds a base fare to your next subway trip.

Frequently Asked Questions

How much does a T-money card cost?
The card itself is ₩2,500–4,000 depending on the design, and that fee is not refundable. Balance loaded onto the card is separate and can be refunded.

Can I get a refund at the airport?
Yes, for small balances at convenience stores inside the terminal, but you must do it before passing through security. Larger balances need a subway station service centre, which means handling it before you head to the airport.

Is there a fee to refund a T-money card?
₩500 at convenience stores and subway service centres. Online refunds charge 4% on the portion above ₩20,000 and require a Korean bank account.

Can I use T-money outside Seoul?
Yes. It works on buses and subways nationwide, including Busan and Jeju, though local transfer rules differ by region.

Can I pay for taxis with T-money?
Yes, most taxis accept transit cards, as do convenience stores for ordinary purchases.

What if I forget to refund it?
Nothing expires immediately — the balance stays on the card. If you return to Korea it will still be there, and you can also refund it on a later trip.
