Can I Use Credit Card on Korea Buses? Payment Guide 2026
You cannot tap a foreign credit card directly on Korean city bus card readers the way you might in London or Sydney. Almost all city buses in Seoul, Busan and other Korean cities require a rechargeable transport card such as T-money (티머니) or Cashbee (캐시비), or exact-change cash payment. Some intercity and express buses allow you to buy tickets with a credit card at the terminal counter or online, but on-board payment still defaults to the transport card. After reading this guide, you will know which payment methods work on city buses, intercity coaches and airport limousine buses, how to buy and reload a transport card, and when you actually need cash or a Korean-issued card.
- City buses

Why foreign credit cards do not work on Korean bus readers
Korean city buses use a domestic contactless transport-card standard that is separate from international Visa payWave, Mastercard contactless or Apple Pay bank-card networks. The card readers installed on Seoul, Busan, Daegu and other city buses are designed to communicate only with T-money (티머니), Cashbee (캐시비) and a handful of other Korea-specific rechargeable cards. These readers do not recognise the chip or contactless signal from a foreign Visa, Mastercard or American Express card, even if your card works for contactless payment at a shop or restaurant.
This is different from transport systems in London, Sydney or Singapore, where you can tap a foreign contactless bank card directly on the gate or reader. Korea's transport-card system predates the widespread international contactless-payment standards, and operators have not retrofitted buses with dual readers that accept both domestic transport cards and international bank cards. The installed base is large and the existing T-money ecosystem works reliably, so there has been little commercial pressure to change.
Some foreign visitors try Apple Pay or Google Pay on the bus reader. These will fail unless the digital wallet holds a Korean-issued transport card or a Korean-issued credit card registered with the local contactless rail and bus network. A foreign bank card tokenised in Apple Pay is still just a foreign bank card to the reader. The only practical solutions are to carry a rechargeable transport card loaded with Korean won, or to pay the driver in exact-change cash if the bus route permits it, which many do not.
How to get and use a T-money or Cashbee card
T-money (티머니) and Cashbee (캐시비) are the two main rechargeable transport cards that work nationwide on city buses, subways and some taxis. You buy a physical card once, load it with cash, and tap it on the card reader when you board and alight. Both cards are functionally identical for foreign travellers; T-money has slightly wider acceptance on taxis and at convenience-store payments, while Cashbee is issued by some banks and has a loyalty programme that matters little to short-term visitors. Either card works on Seoul, Busan, Daegu, Incheon, Gwangju and Daejeon buses and metros.
You can buy a T-money or Cashbee card at any CU, GS25, 7-Eleven or Ministop convenience store, which are found in every neighbourhood and inside most subway stations. Ask the clerk for a "T-money card" (English is fine, or say "티머니 카드") and hand over roughly 2,500-4,000 KRW in cash. Character editions featuring cartoon mascots or K-pop groups cost about 4,000-5,000 KRW. The card price itself is not refundable, but the stored balance is, so treat the card as a small souvenir. Subway station vending machines also sell and reload cards; the machines have an English-language option and accept cash.
Once you have the card, reload it with cash at the same convenience stores or at any subway-station kiosk or ticket machine. Tell the clerk how much you want to load (say "10,000 won, please" and hand over a banknote), and the clerk will scan the card on the reader and add the balance. Machines accept banknotes and will print a receipt. A 10,000 KRW top-up typically covers a few days of city bus and subway rides. The Seoul subway base fare is 1,550 KRW with a transport card for the first 10 km, and bus fares are similar, so 10,000 KRW gives you six to eight one-way trips depending on distance.
To use the card, tap it on the card reader next to the driver when you board the bus, and tap again on a reader near the exit door when you alight. Korean buses charge by distance or by transfer, so both taps are required to calculate the correct fare. If you forget to tap out, the system may deduct a maximum fare or flag the card. The same card works on subway turnstiles, where you tap in and tap out just as you would in any metro system. Check your remaining balance on the screen each time you tap, or ask the convenience-store clerk to check it when you reload.
Paying with cash on city buses
Most Korean city buses accept exact-change cash payment into a fare box next to the driver, but the system is less convenient than using a transport card and may cost more. The cash fare is typically 100 KRW higher than the transport-card fare. For example, if the card fare is 1,550 KRW, the cash fare may be 1,650 KRW. You must have the exact amount in coins or small banknotes; drivers do not carry change and cannot break a 10,000 or 50,000 KRW note. The fare box is a one-way chute with no refund mechanism.
A bigger limitation is that cash payment forfeits the free or discounted transfer benefit. Korean city transport systems allow you to transfer between buses and subways within 30 minutes (or sometimes longer) and treat the combination as a single journey with one base fare, provided you use the same transport card for both taps. If you pay cash on the first bus, the system has no record of your journey, so the second bus or subway will charge you a fresh full fare. For a traveller planning to transfer, this effectively doubles the cost. If you pay cash on the bus, you must insert the exact fare into the fare box when you board, and you do not tap out when you alight.
Cash is a practical fallback only if you have exact change, you are not planning a transfer, and you cannot find a convenience store or subway station to buy a transport card. In practice, convenience stores are so ubiquitous in Korean cities that it is almost always faster to walk an extra block and buy a T-money card than to hunt for exact coins. The only scenario where cash on the bus makes sense is a one-off short ride in a remote rural area where you have no other payment option and the driver waves you on with an approximate handful of coins. Even then, many intercity and rural buses now require prebought tickets rather than on-board payment.
Intercity and express bus payment options
Intercity buses (시외버스) and express buses (고속버스) that travel between cities operate differently from city buses. You almost always buy a ticket in advance at the terminal ticket counter, at a self-service kiosk, or online through platforms such as Kobus (kobus.co.kr) or T-money's intercity booking site (txbus.t-money.co.kr). These platforms and terminal counters typically accept international Visa and Mastercard credit cards, as well as Korean-issued cards and mobile payment apps. You board the bus with a printed ticket, a mobile QR code or a booking confirmation, and you do not tap a card reader on boarding.
Some intercity routes that stop at villages or smaller terminals allow passengers to pay the driver directly with cash or a transport card, but this is becoming rare. If you plan to take an intercity bus, assume you need to buy a ticket at the terminal before departure. The ticket price depends on distance and comfort level (standard, deluxe or premium) and may range from roughly 5,000 KRW for a short intercity hop to 30,000 KRW or more for a long-distance express coach. Ticket counters have English signage in major terminals, and the Kobus website has an English interface. You can check schedules, compare operators and pay with a foreign credit card online, which is often easier than navigating a busy terminal.
Airport limousine buses that run from Incheon or Gimpo airports to hotels and neighbourhoods in Seoul also require prebought tickets. You buy a ticket at the airport bus-ticket counter in the arrivals hall, usually for around 10,000-16,000 KRW depending on the route. The counter accepts credit cards and cash. Some limousine buses allow you to tap a T-money card on a reader if you board at certain stops in the city, but the airport-to-city route almost always requires a ticket. Once on board, there is no card reader or fare box; the driver checks tickets as passengers board or presents a QR scanner for mobile tickets.
Mobile apps and digital wallets for transport
Korea has mobile versions of T-money that you can load onto a smartphone and use by tapping the phone on a card reader, similar to Apple Pay or Google Pay in other countries. However, these mobile transport cards are generally available only on Korean Android phones with NFC and a Korean-issued SIM or mobile-carrier account. iPhones sold outside Korea do not support Korean transport-card NFC protocols at the time of writing, and foreign Android phones may lack the required NFC chip configuration or the local mobile-carrier integration. If you have an iPhone purchased in the US, UK or Australia, you cannot currently add a T-money card to Apple Wallet and tap your phone on bus readers.
Some Korean mobile-banking and payment apps, such as Kakao Pay (카카오페이) and Naver Pay (네이버페이), allow you to register a plastic T-money card and check its balance, but this does not turn your phone into the card itself unless the phone has the compatible hardware and you have a Korean bank account or phone plan. For almost all foreign visitors, it is simpler and more reliable to carry a physical T-money or Cashbee card than to attempt a mobile setup that may not work with your device.
That said, if you have a long stay in Korea and open a Korean bank account or get a Korean SIM card on a postpaid plan, you may be able to register for mobile T-money through the T-money app or your carrier's wallet app. This is a multi-step process requiring identity verification and a Korean phone number, so it is practical only for residents or long-term visitors. Short-term travellers should budget two or three minutes and 5,000 KRW to buy a plastic card and reload it as needed; the physical card is inexpensive, works every time, and doubles as a small souvenir.
Credit card acceptance at transport terminals and stations
While you cannot use a foreign credit card on the bus vehicle itself, you can use credit cards at many points in the Korean transport system. Subway ticket vending machines accept international credit cards for buying single-journey tickets, though the card rate for a single-journey ticket (1,650 KRW in Seoul for the base fare) is slightly higher than the rechargeable-card rate, and you pay a 500 KRW deposit for the plastic token, which you reclaim at a deposit-refund machine after you exit. This is practical for a one-time trip, but it is more expensive and time-consuming than using a transport card if you plan multiple rides.
Intercity and express bus terminals have ticket counters and self-service kiosks that accept international credit cards. Major terminals such as Seoul Express Bus Terminal (서울고속버스터미널), Dong Seoul Bus Terminal (동서울종합터미널) and Central City Terminal (센트럴시티터미널) have English-language kiosks and staff who can process card payments. Smaller rural terminals may be cash-only at the counter, so always carry some cash as a backup. The Kobus online booking platform accepts Visa and Mastercard and is often the easiest way to buy intercity tickets in advance, especially if you are travelling during a Korean public holiday when buses fill up quickly.
KTX and SRT high-speed trains, which compete with intercity buses on long routes, allow you to buy tickets with international credit cards at station counters, ticket machines and online through the Korail website (letskorail.com) and the SRT app. Ticket machines at Seoul Station, Yongsan Station and other major hubs have English interfaces and accept chip-and-PIN cards. If your card is chip-and-signature, the machine may decline it, in which case use the staffed ticket counter. Mobile-ticketing apps such as Kakao T (카카오 T) and Naver Map sometimes require a Korean credit card or phone-based payment method, but their English interfaces are improving and foreign-card acceptance is gradually widening. For city buses, though, none of these payment options help; the physical card reader on the bus itself will only respond to a domestic transport card or cash.
What to do if your T-money card stops working
T-money and Cashbee cards are durable, but they can occasionally malfunction if the embedded NFC chip is damaged by bending, water or strong magnets. If you tap your card and the reader beeps with an error tone or displays a red X, first check your balance. The most common cause of a failed tap is insufficient balance. Reload the card at a convenience store or subway ticket machine and try again. If the reader still rejects the card and you know the balance is sufficient, the card may be physically damaged or demagnetised.
You can check the card balance and transaction history at a convenience-store card reader (ask the clerk to check it for you) or at a balance-check kiosk inside subway stations. If the card reads as zero balance or unreadable, the chip may be broken. Unfortunately, physical damage to the card is not covered by any warranty, and the card itself is not refundable. You will need to buy a new card and transfer any remaining balance if the old card is still readable. Some subway-station kiosks and convenience stores have a balance-transfer function that copies the stored value from an old card to a new one, but this requires both cards to be readable by the machine. If the old card is completely dead, the balance is lost, which is why it is wise to load only 10,000 or 20,000 KRW at a time rather than 50,000 KRW.
If you are leaving Korea and have remaining balance on a working card, you can refund it at convenience stores or designated refund kiosks in subway stations and airports. The clerk or machine will deduct a small processing fee (usually 500 KRW) and return the remaining balance in cash. The card itself is not refunded; you keep it or discard it. Many travellers keep the card as a souvenir or for a future trip, since T-money cards do not expire and can be reloaded years later.

Practical tips
Frequently asked questions
Before you go
Foreign credit cards do not work on Korean city bus card readers, so you need a rechargeable T-money or Cashbee card for almost all bus and subway travel. Buy the card at a convenience store or airport for roughly 2,500-4,000 KRW, load it with 10,000-20,000 KRW to start, and tap it on and off every bus and subway ride. Intercity and express buses let you buy tickets with a credit card at the terminal or online, but city buses require the transport card or exact-change cash. The card is inexpensive, widely accepted and reloadable anywhere, making it the single most useful payment tool for navigating Korean public transport.
