T-money Card Guide (2026): How to Use Korea's Transit Card

T-money card guide for travelers in Korea — how to buy, recharge, tap in and out, get transfer discounts, and refund your balance on subways, buses, AREX, and taxis.

Getting around Korea comes down to one small card. Buy a T-money card, load it with cash, and tap in and out — that's it. The same card works on the subway, city buses, the AREX airport line, taxis, and even convenience stores, all over the country.

Here's the short version: pick up a T-money card at any convenience store for about ₩2,500–4,000, top it up with Korean cash, then tap the reader when you board and again when you get off. Tapping out matters — it's how you get the distance fare right and keep your transfer discounts (source: official T-money guide).

Hi there. I put this together because a lot of visitors still arrive unsure whether they can just tap a foreign credit card at the gate (short answer: not yet — more on that below). Sources are cited inline and listed at the end. A quick, honest note: every price and fare here is approximate and changes, so treat the numbers as a guide and confirm the current amount when you buy or ride.

What a T-money card is (and where it works)

T-money is Korea's national rechargeable transit card — a contactless smart card you tap on and off. It's the dominant prepaid transport card in the country, so once you have one, you rarely need anything else (source: The Seoul Guide; Visit Korea).

The reach is the best part. One card covers most of your movement across Korea:

• Subway: Seoul plus Busan, Daegu, Gwangju, Daejeon, and Incheon (source: Discover Real Korea).
• City buses: nationwide — Seoul's blue, green, yellow, and red buses, Busan buses, and more (source: Visit Korea; Trazy).
• AREX (airport line): works on the All-Stop commuter train, not the Express train (source: Visit Korea).
• Taxis: any taxi showing the T-money logo (source: Visit Korea; The Seoul Guide).
• Convenience stores, cafes, vending machines, some shops, highway tolls, and public phones: as stored-value e-cash (source: Visit Korea).
• Intercity and express buses between major cities (source: Visit Korea).

💡 One card, one person. A single tap moves one rider through the gate — you can't tap a whole family through on one card. Everyone traveling with you needs their own card (standard IC-card rule).

The takeaway: because the same card rides Busan, Daegu, and beyond, you don't need a separate regional card in each city (source: Discover Real Korea).

Where to buy — and what it costs

The easiest place to grab a card is a convenience store. Look for the T-money sign at GS25, CU, 7-Eleven, Emart24, MINISTOP, Story Way, or 365PLUS (source: official T-money foreigner guide).

Other spots:

• Subway stations: ticket vending machines and station information/service centers (Seoul Lines 1–8) (source: Visit Korea).
• Incheon Airport: convenience stores (7-Eleven, GS25) in Terminals 1 and 2, and the Transit Center on B1. There's usually a convenience store right before the AREX platform (source: Travel Guide H).
• Tmoney Town: Seoul Station Exit 10, Seoul City Tower 1F (source: official T-money guide).

What it costs. The basic card runs about ₩2,500–4,000. Character and designer editions — Kakao Friends, BT21, Sanrio and the like — cost more (source: Trazy; Korea With Julia). One thing to note: the official Visit Korea page lists the card at ₩3,000–5,000, so ranges vary by source and store. Either way, the card price itself is a one-time, non-refundable purchase — that fee never comes back, even when you refund your leftover balance (source: official T-money guide).

⚠️ Sources disagree on the exact price. Treat "about ₩2,500–4,000" as a ballpark and expect designer cards to cost more. Verify at the counter.

How to recharge (top up)

Recharging is cash only, in Korean won — that's the long-standing rule at convenience stores and subway machines (source: official T-money guide; Trazy). Keep some bills on you.

The details:

• Amounts: top up in units of ₩1,000, typically ₩1,000–90,000 per transaction (source: official T-money guide).
• Maximum balance: your card holds up to ₩500,000 (source: official T-money guide; Korea With Julia).
• At a convenience store: hand your card to the cashier, say how much to add, and pay in cash.
• At a subway machine: insert the card, choose recharge, and feed in cash — machines usually take bills only, so keep ₩1,000 / ₩5,000 / ₩10,000 notes handy.

Checking your balance is easy: the simplest way is to ask the convenience-store cashier when you hand over the card. Your balance also flashes on the reader when you tap to ride or pay, and shows at subway machines (source: Korea Locally).

The 2026 exception. Since around March 2026, new Seoul Metro kiosks let you recharge with overseas credit/debit cards plus Apple Pay, Kakao Pay, and Naver Pay — a 3.7% service fee applies on overseas cards. These kiosks are limited to 273 stations on Lines 1–8, so cash is still the default everywhere else (source: Korea Herald). More on this launch below, because it's widely misreported.

How to use it: tapping, fares, and transfers

The rule that trips people up: tap in AND tap out. On the subway, tap the gate reader to enter and tap again to exit — the distance-based fare is deducted when you leave. On buses, tap when you board and tap again when you get off (source: official guide; multiple).

Fares (Seoul — verify current)

• Subway base fare: ~₩1,550 for up to 10 km, then +₩100 per additional 5 km band. This rose from ₩1,400 on June 28, 2025 (source: Korea Herald).
• City bus base fare: ~₩1,500 by card for the main blue/green buses; some yellow circulation buses are cited at ₩1,400 (source: Visit Korea).
• Card discount: paying by T-money gives you roughly ₩100 off per ride versus a cash single ticket, on top of transfer savings (source: Visit Korea; official guide).

⚠️ Some 2026 travel pages still quote old subway fares of ₩1,250 or ₩1,400 — those are outdated. Use ~₩1,550 as the current base fare, and confirm the amount when you ride, since it changes.

The transfer discount (your biggest money-saver)

This is where T-money quietly pays for itself. Transfer between bus ↔ subway and bus ↔ bus and you only pay the extra distance — not a whole new base fare (source: official T-money guide; Trazy).

• Window: tap the next vehicle within 30 minutes of tapping off (extended to 1 hour between 21:00 and 07:00).
• Limit: up to 4 transfers per day.
• The catch: you must tap out. Forget to tap off, and you can lose the discount and even pick up a penalty on your next trip.

💡 If you only remember one thing about buses, it's this: always tap out. That single habit protects both your fare and your free transfers.

Refunds: getting your balance back

You can refund your remaining balance when you leave — but not the card fee. The card cost plus a ~₩500 service fee are not returned, and you keep the physical card (source: official T-money guide; Trazy).

Where to do it:

• Convenience stores: refund smaller leftover balances, minus the ₩500 fee. The exact ceiling varies by store — commonly cited as up to a limit somewhere around ₩20,000–50,000 (sources conflict; see below).
• Larger balances: handled at Tmoney Town or Tmoney service centers in subway stations. The official guide describes partial refunds of ₩10,000–50,000 in ₩10,000 increments (plastic cards only) (source: official T-money foreigner guide).
• At the airport: you can get a balance refund at convenience stores inside Incheon Airport, before security (source: Unnie's Picking).

⚠️ Sources conflict on the refund limit. One guide says balances must be under ₩20,000; another says convenience stores handle up to ~₩50,000; the official guide points larger amounts to Tmoney Town. Safest read: small balances at a convenience store (minus ₩500), larger amounts at a service center — and verify at the point of refund.

A practical shortcut: because the ~₩2,500–4,000 card fee never comes back, many travelers simply spend the balance down at a convenience store before flying out — or just keep the card, since T-money doesn't expire in normal use (source: official T-money guide).

T-money vs. the foreigner cards: which one fits you

Basic T-money is the best all-round default — cheapest, works everywhere, but cash-recharge only. Depending on your trip, one of the tourist-focused variants might suit you better. Here's how they compare.

Card	What it is	Recharge	Best for
T-money (basic)	Korea's universal transit card	Cash only (KRW)	Anyone — cheapest, works nationwide
Korea Tour Card	A T-money card for tourists with partner discounts	Cash, or foreign cards via the KOREA TOUR CARD app (Android)	Tourists who want extra shop/attraction perks
WOWPASS	Prepaid debit + built-in T-money + currency exchange (two wallets)	Feed foreign cash (USD/EUR/JPY…) into a kiosk	One card for transit + spending + money exchange
NAMANE	Custom-photo prepaid debit + transit (uses Rail+, not T-money)	Top up anywhere via its app	Cashless travelers who want a personalized card
M-Pass	Foreigner-only unlimited pass, up to 20 rides/day	Reloadable as T-money afterward	Heavy Seoul-area riders incl. AREX All-Stop
Climate Card	Seoul unlimited pass (subway + Seoul city buses)	Cash; foreign cards at 2026 kiosks	Seoul-only stays with lots of daily rides

A few details worth knowing (all approximate — verify current):

• WOWPASS cards cost about ₩5,000, with kiosks at most major subway stations and Incheon Airport. It keeps two separate balances: a shopping/debit wallet and a T-money transit wallet (source: Seoul Explorer; Visit Korea).
• NAMANE works the same on subways and buses nationwide, but runs on the Rail+ system rather than T-money (source: Seoul Explorer).
• M-Pass covers Seoul-area subway, city buses (green/blue/yellow), and AREX All-Stop (not the Express). Prices per Visit Korea: 1-day ₩15,000 / 2-day ₩23,000 / 3-day ₩30,500 / 5-day ₩47,500 / 7-day ₩64,500, valid 30 days from issue, with ₩3,000 off if bought after 5 PM (source: Visit Korea).
• Climate Card costs ₩3,000 for the physical card. Its tourist short-term passes come in 1, 2, 3, 5, and 7-day versions, roughly ₩5,000 (1-day) up to ₩20,000 (7-day) (source: Seoul Metropolitan Gov). Note: the short passes cover Seoul subway and city buses only — not valid outside Seoul, and they don't include Ttareungi bikes or the Hangang river bus (source: Seoul Gov).

💡 Quick match: Seoul-only with lots of rides → Climate Card short pass. Transit + spending + currency exchange in one → WOWPASS. Simple, nationwide, cheapest → basic T-money or Korea Tour Card. Heavy Seoul-metro rider including AREX → M-Pass.

The 2026 update everyone gets wrong

You may have read that you can now "just tap your foreign credit card at the gate" in Seoul. That's not quite true yet, and it's the most common mistake in recent guides.

Here's what actually launched around March 16–17, 2026: Seoul Metro added 440 self-service kiosks at 273 stations on Lines 1–8. These kiosks accept overseas credit/debit cards (Visa, Mastercard, JCB, UnionPay, Amex) and Apple Pay / Kakao Pay / Naver Pay — but only to buy and recharge T-money and Climate Cards and to buy single tickets. A 3.7% fee applies on overseas cards (source: Korea Herald; Seoul Metropolitan Gov).

So the 2026 change is about buying and topping up, not tapping your Visa at the turnstile.

True open-loop EMV tap — waving your own credit card straight at every gate and bus reader — is a phased rollout planned through ~2030: bus terminals and payment servers first (2025–26), EMV terminals on Lines 1–8 next (2027), then town buses and private railways (2028–30) (source: Seoul Metropolitan Gov; Korea Times).

The practical bottom line for a mid-2026 trip: you still need a transit card (T-money, WOWPASS, or similar) — or one of the new kiosks — to ride. Flag this as newly launching and limited, and check the current status before you rely on it.

A few practical tips

• Keep a small buffer. A failed tap for insufficient funds at a bus door or gate is awkward. Top up ~₩10,000–20,000 for a few days of riding.
• It works beyond Seoul. The same card rides Busan, Daegu, Daejeon, Gwangju, and Incheon subways and buses, plus intercity buses — no regional card needed (source: Discover Real Korea).
• Use it off the rails too. Tap to pay taxis showing the T-money logo, and buy snacks or drinks at CU, GS25, 7-Eleven, Emart24, and vending machines with your balance.
• Carry some cash for recharging outside the new kiosk stations — most top-ups are still cash-only.
• Traveling as a group? Each person needs their own card. No shared taps.

Summary

A basic T-money card is the simplest way to move around Korea: buy it at a convenience store, load it with cash, and tap in and out on subways, buses, AREX, and taxis nationwide. Tapping out is what protects your fare and your transfer discounts. When you leave, refund the leftover balance — the card fee itself doesn't come back.

If you only remember one thing: get a T-money card, load cash, and always tap out — the card fee is non-refundable, and the March 2026 kiosks let you buy/recharge with a foreign card, but you still can't tap that card at the gate.

Final thoughts

• For most travelers, honestly, plain T-money is still the best default — it's the cheapest, works in every city, and does everything you actually need.
• The Climate Card and WOWPASS are genuinely useful for the right traveler (Seoul-heavy stays, or one card for money + transit), so it's worth matching the card to your trip rather than defaulting to whatever a blog pushed.
• The biggest thing to get right in 2026 is the open-loop myth: the new kiosks help you buy and top up with a foreign card, but gate-tapping your own credit card is still years away in most places.

⚠️ Every price, fare, and refund limit here is approximate and time-sensitive — the card price, ₩1,550 subway fare, refund ceilings, and kiosk coverage all change and vary by source. Confirm the current amount when you buy, ride, or refund.
