The first time I stood at a Seoul convenience store checkout holding a crisp 1,000-won note, the cashier looked at it like I'd handed him something obsolete. He didn't say anything rude. He just gestured toward the card reader. Card is the default mode across Korea. Walk into any CU or GS25 in Myeongdong, sit down at a Korean barbecue place in Hongdae, grab coffee at any Hollys branch in the country: the terminal comes out before you've finished ordering. Knowing how to handle that moment in Korean makes a small but real difference.
신용카드 and Its Close Relatives
신용카드 (sin-yong-ka-deu) is the word you need. The first half, 신용 (sinyong), means 'trust' or 'creditworthiness.' The second half, 카드, is borrowed directly from the English 'card.' Together they track closely enough to the English phrase that most people recognize the word immediately when they hear it. Credit card goes deeper into the pronunciation if you want to hear the syllable breaks clearly. The companion word is 체크카드 (chekeu kadeu), which Koreans use for debit cards — cards that pull directly from your bank account rather than running a credit line. The distinction comes up at checkout more than you'd expect. When a cashier asks which kind you have, knowing both words saves you from pointing at your wallet and hoping. Debit card has the details on that one. For casual shorthand, 카드 by itself works in most contexts. Saying 카드로요 ('by card, please') at a convenience store gets the point across immediately.
Seoul Runs on Plastic
Korea is consistently among the world's top countries for credit card usage per capita. That's visible at street level. Walk the length of Insadong on a Saturday: even the small stalls selling ceramics and traditional snacks have portable card readers propped near the cash box. Namdaemun Market, long known as a cash-first destination, has shifted steadily toward card acceptance across most of its vendors. The preference for cards isn't just habit. The Korean government introduced card-linked tax deduction incentives in the early 2000s, making it genuinely advantageous for Koreans to pay by card. That policy shaped spending patterns fast. I've watched vendors at the Gwangjang Market food alley set up card readers between steaming plates of bindaetteok without missing a beat. Cash isn't gone. It's still worth carrying in smaller towns, at some pojangmacha tents, and at the handful of traditional spots that explicitly ask for it. But in Seoul and every major city, card is the default assumption.
The Checkout Question Every Cashier Asks
Here's the part most Korean phrase books skip. Every time you pay by credit card in Korea, the cashier will ask: 일시불이에요, 할부에요? (il-si-bul-i-e-yo, hal-bu-e-yo?) Translation: 'One lump sum, or installment?' 일시불 (il-si-bul) means paying the full amount at once, which is what virtually every foreign card will process by default. The word breaks down as 일 (one) + 시 (time) + 불 (payment). Installment payment covers 할부 in depth, but for most visitors 일시불 is the correct answer every single time. The right response is 일시불로요 (il-si-bul-lo-yo). Short, clear, done. If you blank and say nothing, the cashier will typically punch in 일시불 by default. But knowing the phrase means you're not left parsing a question you don't recognize. The checkout moves faster once that click happens in your brain.
Phrases That Cover Every Payment Situation
These are the phrases worth learning before your trip. They're short enough to pick up in a single session:
- 카드로 해주세요 (ka-deu-ro hae-ju-se-yo): Please charge this to my card.
- 일시불로요 (il-si-bul-lo-yo): One payment, please.
- 영수증 주세요 (yeong-su-jeung ju-se-yo): Receipt, please.
- 카드 돼요? (ka-deu dwae-yo?): Do you accept cards?
- 얼마예요? (eol-ma-ye-yo?): How much is it?
카드 돼요? is useful for smaller restaurants or outdoor vendors where card acceptance isn't obvious. Most will just point at the terminal. A few will say 현금만요 ('cash only'), which is when you'll be glad you kept some 원 in your pocket. For receipts, you'll sometimes be asked whether you want a receipt printed or sent digitally. The printed version is 종이 영수증 (jong-i yeong-su-jeung, 'paper receipt') and the digital is 전자 영수증 (jeon-ja yeong-su-jeung). For most purchases, the cashier offers without being asked. Card payment covers the full transaction vocabulary for when you want to go beyond basics. Payment gives you the broader noun for conversations outside the checkout line.
T-Money and the Cards You Won't Swipe
If you're riding the Seoul Metro or taking a city bus, your credit card won't tap the transit turnstile. Korea's public transit system runs on T-money (T머니), a rechargeable contactless card you can buy at any GS25 or CU for around 2,500 won and top up at the gate machines. T-money is independent of your bank account and doesn't need a Korean phone number or local banking relationship. It's the simplest transit solution for any stay longer than a couple of days. You can also use it at most convenience stores for small purchases. On the app side, Koreans pay constantly via KakaoPay and Naver Pay. As a visitor with a foreign banking setup, those apps aren't easy to access. If you hear 간편결제 (gan-pyeon gyeol-je) around you at the counter, that's 'simple payment' or 'easy pay' — you'll find the full breakdown on the payment app page.
Common questions
Q: What is the Korean word for credit card?
신용카드 (sinyong kadeu) is the standard term. 신용 (sinyong) means 'trust' or 'creditworthiness,' and 카드 is a loanword from English 'card.' The full word sounds close enough to 'sinyong card' that most English speakers can approximate it on the first try. At checkout you can shorten it to 카드로요 ('by card, please') and every cashier understands. For a complete phrase, 신용카드로 해주세요 ('please charge it to my credit card') leaves no ambiguity. The credit card word page has pronunciation audio if you want to hear the exact syllable breaks before your trip.
Q: What does 일시불 mean when a Korean cashier asks?
일시불 (il-si-bul) means 'one lump sum payment,' meaning the full charge goes through at once rather than splitting across several months. Korean credit cards can process in monthly installments (할부), which is why cashiers ask every time. For most foreign cardholders, your home bank won't support the Korean installment system, so 일시불로요 is always the right answer. The word comes from 일 (one), 시 (time), and 불 (payment). Once you know those pieces, it's easy to reconstruct from memory. You'll hear this question at every card payment in Korea. See installment payment for the full 할부 breakdown.
Q: Can I use a foreign credit card in Korea?
Foreign Visa, Mastercard, and Amex cards work at most Korean payment terminals without issue. Convenience stores, chain restaurants, department stores, and tourist-area shops are generally fine. Some smaller vendors and traditional market stalls run Korean-card-only systems, so it's worth keeping some Korean won in your wallet as a backup for those moments. Any surcharges come from your home bank's foreign transaction policy, not the Korean terminal, so check those fees before you travel. If a cashier seems uncertain about your card, saying 해외카드예요 (hae-oe-ka-deu-ye-yo, 'it's an overseas card') usually clears things up fast.
Paying Like You Already Know the Language
A handful of words carries you through almost every payment interaction in Korea: 신용카드, 일시불, 영수증, 카드 돼요?. Once you've heard 일시불이에요, 할부에요? a couple of times, you'll answer without thinking. That's the moment Korean stops feeling like a foreign phrase you're retrieving and starts feeling like something you just know. Koko AI has word pages for dozens of payment and everyday finance terms. Explore them one at a time and you'll find the checkout conversation gets shorter with each visit.
