T-money and Cashbee cards: the essential guide for getting around Busan
Do I need a T-money card for Busan's metro?
Yes, practically speaking. Busan's metro does not accept contactless credit cards or Apple Pay as of 2026 — you pay with a T-money card or buy a single-journey cash token each time. T-money also gives you a 10% discount on every ride and free transfers between metro and bus within 30 minutes. Buy one at any convenience store before your first journey.
Why a transit card is not optional in Busan
Busan has a clean, well-signed, air-conditioned metro system with four lines covering most places visitors want to reach — Haeundae, Gwangalli, Seomyeon, Nampo, the KTX station at Busan Station, Gimhae Airport on the dedicated airport rail. On paper, it sounds straightforward. In practice, there is one catch that catches a surprising number of first-time visitors off guard: Busan’s metro does not accept tap-to-pay credit cards.
No Visa contactless. No Mastercard tap. No Apple Pay. No Google Pay. As of mid-2026, the fare gates in Busan accept two things: a T-money transit card, or a single-journey token purchased from a ticket machine with cash. That is it.
This matters because travellers who arrive with a modern wallet — expecting to tap their phone or credit card like they would in London, Singapore, or Tokyo — walk up to the fare gate and find themselves with no way through. The alternative (single-journey tokens) works, but it means queuing at a ticket machine for every single journey, paying the slightly higher cash fare of ₩1,700 instead of the card fare of ₩1,600, and losing all transfer discounts. Over a week of daily metro use, the friction and the cost difference add up.
The fix is simple: buy a T-money card before or immediately upon arrival. This guide tells you exactly how.
| Where to buy | Gimhae Airport arrivals, or any GS25/CU/7-Eleven |
| Cost | ₩2,500 card deposit + initial load (₩10,000–20,000 typical) |
| Fare saving | ₩1,600 card vs ₩1,700 cash per journey |
| Transfer window | 30 minutes between metro/bus for discount |
| Refund | Balance + ₩2,500 deposit minus ₩500 fee, at any major convenience store |
For the full picture of how Busan’s metro system works — lines, zones, journey times — see the Busan metro guide. If you are arriving directly from the airport and want to plan your first journey into the city, the Gimhae Airport to city centre guide covers the airport rail and bus options in detail.
T-money and Cashbee: what they are
T-money is South Korea’s national transit card. It was introduced in Seoul and expanded nationwide; today it is accepted on most public transport across the country — metro systems, intercity and city buses, some taxis — and also at convenience stores for everyday purchases. Think of it as an RFID chip on a card that you preload with Korean won, then tap to pay. The balance sits on the chip, not on an account, which means it works without internet, phone signal, or a bank card.
Cashbee is a competing card that originated in Busan and the southeastern region of Korea. Historically it was the dominant transit card in Busan while T-money dominated Seoul. Today that distinction has largely dissolved: both cards are accepted on Busan metro, city buses, and most convenience stores in the region. You are unlikely to find a situation in Busan where one works and the other does not.
Neither card is linked to your identity or bank account. You load cash onto them and spend down the balance. If you lose one, the remaining balance is gone — there is no recovery mechanism unless you registered the card (which most visitors do not do).
T-money vs Cashbee: which should you buy?
For the practical purposes of a trip to Busan, the cards are interchangeable on transit. The fare, the transfer discount, and the top-up process are identical. The meaningful difference is geographic scope:
T-money is the better choice if you are also travelling to Seoul, Gyeongju, Daegu, or anywhere else in Korea during your trip. It is accepted on Seoul’s metro, on many intercity buses, and widely recognised nationwide. If you ride the KTX back to Seoul, you can use the same T-money card on Seoul’s subway from the moment you arrive.
Cashbee is equally fine if you are staying in Busan for your entire visit. It works on everything that matters locally. It is sold at Family Mart and other convenience stores in Busan; in Seoul-based or national chains like GS25, T-money tends to be more prominently stocked.
Verdict for most visitors: buy T-money. Not because Cashbee is worse, but because T-money’s national coverage removes one decision if your itinerary changes. Both cost the same (₩2,500 card deposit plus your initial load), and both do the same job in Busan.
Where to buy a card
At Gimhae Airport
The fastest option: convenience stores in the arrivals hall sell both T-money and Cashbee. Before you clear the arrivals area, grab a card, load ₩10,000–20,000, and you are ready to board the airport rail or bus immediately. There is no reason to hunt for a card after you land — it is right there.
The Gimhae Airport to city centre guide covers the journey options in more detail.
At metro stations
Most metro stations have vending machines that sell single-journey tokens. Some machines also sell T-money cards, but this varies by station. Do not rely on this as your primary plan — convenience stores are more reliable for purchasing a new card.
At convenience stores — the easiest option
GS25, CU, 7-Eleven, Family Mart, and Emart24 all sell T-money cards. There is at least one of these within a short walk of almost every metro station in Busan. This is where the vast majority of locals buy and top up their cards.
One thing to note: the cards are usually behind the counter, not on the shelves. Walk in, go to the cashier, and ask for a “T-money card” — they will know immediately what you mean. The staff at most Busan convenience stores are accustomed to foreign visitors asking for transit cards and will show you the options without needing Korean.
Cost: ₩2,500 deposit for the card itself, plus however much you want to load initially. The ₩2,500 deposit is refunded when you return the card, minus a ₩500 handling fee (see the refund section below).
How to load (top up) your card
At metro station machines
Every metro station has fare machines, and all of them have an English-language option. Select “T-money recharge” or equivalent on the screen, tap your card on the reader, insert cash, and confirm. The minimum top-up amount is ₩1,000, but machines typically prompt for round amounts — ₩5,000, ₩10,000, ₩20,000. Loading ₩10,000 before a day of exploring gives you comfortable headroom; a standard metro journey costs ₩1,600, so that covers six or seven rides with change left over.
At convenience store counters
Hand your card and the cash you want to load to the cashier and say “T-money charge” (or “tee-moni chaji” if you want to attempt Korean phonetics). They will tap the card on their reader, process the amount, and hand it back. Straightforward, fast, no language barrier issues in practice.
Keep the receipt if you want a record of the transaction — the machines and store systems do not send confirmation messages.
Recommended load amounts
For a week in Busan with daily metro use and some bus journeys: ₩20,000–30,000 total across your stay is typically sufficient. Load in increments that feel comfortable — ₩10,000 at a time is a sensible unit since metro machines and convenience stores both handle it cleanly. If you are heading to areas further from the centre (Dadaepo Beach on the western end of Line 1, for instance), top up before you go rather than hunting for machines at quieter stations.
Where T-money works in Busan
Busan Metro — all four lines
T-money and Cashbee work on every line of the Busan metro: Line 1 (orange, north-south from Nopo to Dadaepo Beach), Line 2 (green, east-west through Haeundae and Seomyeon), Line 3 (brown, inner circular), and Line 4 (blue, northeastern route via Minam). The fare is ₩1,600 per journey at the base zone, versus ₩1,700 if you pay cash — a 6% saving on each individual ride, which compounds over a trip with multiple daily journeys.
For route planning on all four lines, the Busan metro guide has station-by-station details.
City buses
T-money is even more important on buses than it is on the metro. Bus fare payment in Busan is handled almost entirely by card tap — the alternative is having exact change in coins and notes, since bus drivers cannot make change. Getting onto a Busan city bus with only a credit card and no T-money means either you have exact change ready (unlikely for tourists) or you negotiate with an impatient queue behind you.
Tap on when you board, tap again when you exit — both taps matter for the transfer discount system explained below. If you forget to tap off, you will not be charged extra, but the system will not register a completed journey, which affects transfer eligibility.
Some taxis
Many Busan taxis accept T-money. Look for a T-money sticker on the window or dashboard — it is usually visible from outside the vehicle. Payment by T-money is tap-on-the-reader at the end of the journey. Not all taxis participate, and there is no penalty for asking the driver before you get in. Kakao Taxi (Korea’s ride-hailing app) shows payment method options when booking.
No tipping in Korea — in taxis or anywhere else. The meter fare is the full fare.
Convenience stores
Every GS25, CU, 7-Eleven, Family Mart, and Emart24 accepts T-money for purchases. This makes the card genuinely useful beyond transit: you can pick up water, snacks, a coffee from the self-serve machine, or triangle kimbap and pay by tapping the card on the reader at the till. The balance is deducted from your card just as it would be for a metro fare.
This also gives you a natural way to use down remaining balance at the end of your trip — more on that below.
What T-money does not cover
T-money is not a general-purpose payment card in Korea. It will not work at most restaurants, cafes, shops, museums, or tourist attractions. Most of those accept credit cards (Visa and Mastercard are widely accepted), and many now accept Apple Pay and Samsung Pay at the point-of-sale terminal. The divide is specifically transit and convenience stores versus everything else.
The transfer discount: how it works and why it matters
This is the feature most visitors either never learn about or understand correctly.
When you exit a metro station or get off a bus, a 30-minute window opens. If you board another bus or metro within that 30 minutes, the second journey is either free (if the fare has already been “used”) or significantly discounted. The system is designed to make multi-leg journeys — a metro to a bus, or a bus to a metro — feel like a single continuous trip rather than two separate fares.
In practice: tap off when you leave the metro or bus (do not skip this step). Within 30 minutes, tap on to board your next bus or metro. Your card will be charged a reduced amount or nothing, depending on whether the combined distance exceeds the base fare zone. The machine does not ask you to confirm anything — it just calculates and deducts correctly.
This discount is only available with T-money or Cashbee. Single-journey tokens bought with cash get no transfer benefit.
For visitors doing combinations like metro to Haeundae followed by a bus along the beach strip, or metro to Nampo-dong followed by a local bus to the fishing port, the savings and convenience are meaningful over a full day.
Checking your balance
Two easy options:
At metro entrance gates: most stations have a card reader beside the fare gates specifically for balance checks. Tap your card and the remaining balance displays. Takes about two seconds.
At convenience store counters: hand the card to the cashier or tap it on the reader at the till and ask for the balance. They will show you the screen or tell you the amount.
There is no app required and no account registration needed. The balance is stored on the card chip itself.
What to do with the card at the end of your trip
You have three sensible options:
Keep it for your next visit. T-money and Cashbee cards do not expire. If you plan to return to Korea, leaving ₩3,000–5,000 on the card and keeping it in your travel wallet is a completely valid choice. You land, the card still works, and you top up at the airport convenience store.
Use up the remaining balance at convenience stores. In the last day or two of your trip, stop topping up and instead spend down the balance on snacks, drinks, and sundries at GS25, CU, or 7-Eleven. If you time it right you arrive at the airport with near-zero balance, no refund hassle.
Refund at a convenience store. Take the card to any GS25, CU, 7-Eleven, Family Mart, or Emart24 and ask for a T-money refund. They will process it at the till. You receive the remaining balance plus the ₩2,500 card deposit, minus a ₩500 handling fee. So if you have ₩3,000 left on the card, you get back ₩5,000 total (₩3,000 balance + ₩2,500 deposit - ₩500 fee). The minimum refundable balance after the fee is applied is ₩50 — if your card has less than that remaining after deducting the fee, some stores may decline the refund or apply their own minimum.
Note that the refund covers the deposit only at stores that are equipped to handle it — all the major chains are, but a very small independent convenience store occasionally is not. Stick to GS25, CU, or 7-Eleven and you will not have problems.
Credit cards, Apple Pay, and the cash alternative
It is worth being clear on what does and does not work on Busan transit, because misinformation circulates online and gets people into trouble.
Contactless credit/debit cards (Visa, Mastercard tap): do not work on Busan metro fare gates or city buses as of 2026. This includes physical cards with NFC chips and cards added to phone wallets.
Apple Pay and Google Pay: work at many retail shops and some restaurants in Korea, but not on Busan transit. The metro system runs on a proprietary RFID network that requires T-money or Cashbee. This is a infrastructure decision, not a feature gap that gets patched by software updates.
Single-journey tokens: bought at metro vending machines, work for one journey, no transfers. The machine takes cash (Korean won only). You pay ₩1,700 per token, queue each time, and get no transfer discount. A perfectly functional backup if your card is lost or depleted and you need one journey urgently — not a viable daily strategy.
Cash on buses: technically possible if you have exact change, but impractical for tourists. The driver cannot make change. Carrying the precise fare for each bus trip in coins is an avoidable headache.
The bottom line: T-money resolves all of this. The cards are cheap, available everywhere, and work on everything transit-related in the city.
Practical tips for using your card
Load enough before heading to less central neighbourhoods. Metro stations in areas like Dadaepo, Hadan, or the outer reaches of Line 3 and Line 4 have fewer convenience stores nearby. A Seomyeon-area top-up before heading west on Line 1 is easier than scrambling at a quiet suburban station.
Keep the card accessible. T-money works with a tap — you do not need to take it out of a wallet if the wallet is thin enough, but most fare gates work best with the card directly on the reader. A card holder on the back of your phone or a dedicated card slot in a travel wallet makes the tapping process faster and avoids the delay of digging through a full bag with a queue forming.
Card not registered means balance not recoverable if lost. Unlike some national transit systems that offer online account registration and balance transfer, the standard tourist T-money card balance is tied to the chip. If the card is lost or stolen, the balance on it is gone. This is not a reason to panic — ₩10,000 is about $7 — but it is a reason not to preload more than you need for a few days at a time.
The airport rail from Gimhae accepts T-money. The BGLRT (Busan-Gimhae Light Rail Transit) that connects Gimhae Airport to Sasang Station (where you transfer to Line 2) runs on the same T-money system. Buy your card in the arrivals hall before you board.
Language is not a barrier at top-up machines. Metro fare machines have English, Chinese, and Japanese menus. For the T-money recharge function specifically, the UI is minimal — tap card, insert cash, confirm amount — even without reading Korean.
Connecting T-money to the wider Busan experience
Transit cards are the kind of infrastructure that should be invisible — you buy one, it works, and you stop thinking about it. Getting that first purchase out of the way at the airport convenience store before anything else means you arrive in the city already able to move.
From there, the card is your key to the metro network covered in the Busan metro guide, to the airport connection detailed in the Gimhae Airport to city guide, and to the broader question of getting around Busan across its famously sprawling geography.
If you are thinking about cost more broadly, the Busan on a budget guide includes transit costs in the overall daily spend estimates. For visitors wondering whether the Busan City Pass is worth it alongside a transit card — those are two different products addressing different needs, and the City Pass guide explains when the combination makes sense. And if this is your first time in the city and you want the orienting overview before anything else, the Busan first-timer guide covers the neighbourhoods, the rhythms, and the priorities before you dive into logistics.
For currency: if you are still working out how much Korean won to carry and exchange, the currency converter lets you run the numbers in your home currency.
One last practical note: Korea does not have a tipping culture. On taxis, buses, in convenience stores, at restaurants — the price you see is the price you pay. No rounding up, no service charge addition, no expectation of extra cash. This applies to every transaction where you might use your T-money card or pay otherwise.
Registering your card: worth it or not?
Both T-money and Cashbee offer an optional registration process tied to a Korean phone number, which enables balance recovery if the card is lost and access to usage history through an app. For the vast majority of short-term visitors, registration isn’t worth pursuing — it typically requires a Korean phone number and sometimes a Korean bank-linked verification step that isn’t practical to set up for a one- or two-week trip.
The unregistered tourist approach (buy, load, use, refund or keep) works fine for the overwhelming majority of visits and is the path this guide assumes throughout. If you are relocating to Korea longer-term or visiting very frequently, registration becomes worth the setup effort, but that’s a different use case from the typical Busan trip.
T-money for families and groups: one card each or shared?
Families and groups traveling together sometimes ask whether one T-money card can cover multiple people. The answer is no in any practical sense: fare gates require one tap per person passing through, and buses similarly require a tap for each rider — a single card cannot be tapped twice in quick succession for two people walking through together, as the gate will simply reject the second attempt within its cooldown window.
Each traveller, including children old enough to need their own fare (younger children below a certain height typically ride free, verify current thresholds at a station), needs their own card. The practical approach for a family of four: buy four cards on arrival, load each with a similar amount, and keep them distributed so no single lost card strands the whole group without transit access.
Common card problems and how to fix them on the spot
Card not reading at the fare gate: try a different reader position — some gates read better with the card flat against the sensor rather than at an angle. If it still fails, the card may be damaged (cracked chip from being bent in a wallet) or genuinely empty; check the balance at the nearest station reader or convenience store counter. Insufficient balance error mid-journey: this shows at the exit gate rather than the entry gate in most cases, since fares are calculated on exit based on distance travelled; top up at the station’s fare machine before you can exit, using the “fare adjustment” or “insufficient fare” function on the English-language menu.
Lost card: nothing to be done for an unregistered card’s balance — treat the loss as a small, absorbed cost (typically under $10) and buy a replacement at the next convenience store. Card works on metro but rejected on a specific bus: rare, but some older buses have malfunctioning readers; try tapping again, and if it consistently fails, ask the driver — most carry a manual override for genuine reader faults.
Traveling beyond Busan with the same card
If your trip includes a day trip to Gyeongju, Ulsan, or a KTX ride onward to Seoul, the same T-money card follows you. Intercity and city buses across most of Korea accept T-money, and it works on Seoul’s subway from the moment you step off the train — no need to buy a separate card if you’re continuing your trip elsewhere in the country. Cashbee has narrower acceptance outside the Busan region, which is the main reason to default to T-money if your itinerary extends beyond the city.
