If a Korean cashier or card terminal asks about installments, most short-term visitors using a foreign-issued card should choose 일시불. It means making one full payment rather than splitting the purchase over several months.
Do not choose 2, 3, 6, 12, or another month option unless your card issuer has specifically confirmed that the card can use a Korean merchant installment plan. A home-country card app may offer its own post-purchase installment feature, but that is separate from the option shown by the Korean merchant terminal.
Quick answer: Say or select 일시불. If you need a complete phrase, say 일시불로 해주세요, meaning “Please process it as a one-time payment.”
Korea is highly card-friendly. The official VISITKOREA currency and credit card guide says credit cards are widely accepted at major hotels, department stores, and general shops. Approval can still depend on the merchant, terminal, card network, and your issuer.
Why Korean Card Terminals Ask About Installments
Installment purchases are part of Korea’s domestic credit card system. Korean cardholders may be able to divide an eligible purchase over several months, depending on the issuer, merchant, purchase amount, and current promotion.
Many Korean card terminals and checkout flows therefore include an installment field. The same question can appear when a short-term visitor presents a foreign-issued card. Seeing the option does not necessarily mean that the card is eligible for a Korean installment plan.
BC Card’s English terms describe installment transactions as available at domestic merchants authorized by the bank or BC Card. This illustrates that the option is connected to domestic card and merchant arrangements. Read the BC Card English card terms for the domestic-card context.
The Korean Words You May See or Hear
The most useful word is 일시불, pronounced approximately “il-shi-bul.” It means paying the full purchase amount in one card transaction.
You may also see 할부, pronounced approximately “hal-bu.” This means installment payment. A number followed by 개월 indicates the number of months.
| What you see or hear | Meaning | What most foreign travelers should do |
|---|---|---|
| 일시불 | One-time payment or pay in full | Choose this |
| 할부 | Installment payment | Avoid unless your card is confirmed as eligible |
| 몇 개월? | How many months? | Answer “일시불” |
| 3개월 | Three months | Do not select for a normal foreign-card purchase |
| 6개월 | Six months | Do not select for a normal foreign-card purchase |
If the cashier does not understand “full payment,” show the word 일시불 on your phone. The complete phrase 일시불로 해주세요 is also useful.
What to Do If You Selected an Installment Period
Do not assume that selecting a month option created a valid installment plan. Ask the cashier to cancel the unclear attempt and process the payment again as 일시불.
Check the total amount before leaving and keep the receipt for a large purchase, return, or tax-refund claim. Open your card issuer’s app later to confirm that the correct transaction has posted.
If a canceled attempt remains pending, monitor it through the issuer’s app. A pending authorization is not always a completed charge, but only the card issuer can confirm its final status. Contact the merchant and issuer if two completed charges appear.

How to Answer at the Counter
The easiest phrase to prepare is 일시불로 해주세요. It means “Please process it as a one-time payment.” Perfect pronunciation is not necessary; saying “il-shi-bul” while showing the word on your phone is usually enough to communicate the choice.
At a staffed checkout, wait for the cashier or terminal prompt. If the cashier asks “일시불이세요?” or “몇 개월?”, answer 일시불.
At a self-service kiosk, select English when available. If the Korean screen shows month numbers and you are not sure what the buttons mean, do not guess. Cancel the step and ask a staff member or move to a staffed counter.
- Check the total amount in Korean won.
- Choose 일시불 or one-time payment.
- Insert the physical chip card if contactless payment fails.
- Review the final amount before confirming.
- Keep the receipt for larger purchases and refunds.
Installments and Currency Choice Are Different
The installment question is different from Dynamic Currency Conversion, or DCC. The installment prompt asks whether the purchase should be paid in full or divided over several months. A DCC prompt asks whether the card should be charged in Korean won or in your home currency.
Selecting 일시불 answers the payment-type question. If a separate currency screen appears, selecting KRW declines the merchant’s home-currency conversion offer and leaves the conversion to your card network or issuer under the terms of your card.
Visa says a DCC screen should show the transaction amounts, exchange rate, and additional fees or markup, and the customer should be allowed to accept or decline the conversion. Review the Visa Dynamic Currency Conversion guide before deciding.
Your card issuer may still charge foreign-transaction or currency-conversion fees when you select KRW. Check your card’s terms before traveling.
Easy reminder: Choose 일시불 for the payment type. Choose KRW when you want to decline the merchant’s home-currency conversion. These are separate decisions.
What to Prepare Before Paying in Korea
- A physical card: Some terminals work more reliably with chip insertion than with a mobile wallet or contactless card.
- A second card: A card from another issuer or network provides a better backup than two cards tied to the same account.
- A small amount of Korean won: Cash can help with markets, transportation-card top-ups, lockers, and unexpected terminal failures.
- Your issuer’s app: Confirm that overseas in-person payments are enabled and that you can receive security alerts while abroad.
- An appropriate spending limit: Check the daily or per-transaction limit before making an expensive purchase.
Apple Pay and other mobile wallets can be convenient, but they should not be your only payment method. See Apple Pay in Korea for Travelers for a practical backup setup.
Frequently Asked Questions
Can a foreign card use Korean installments?
Most short-term visitors should not expect a foreign-issued card to use a Korean merchant installment plan. Choose 일시불 unless the card issuer has specifically confirmed eligibility.
Your home issuer may separately allow you to convert a completed purchase into installments after it posts. That is an issuer service, not the installment option offered by the Korean checkout terminal.
What should I say if I do not understand the cashier?
Say 일시불 or show the phrase 일시불로 해주세요 on your phone. In English, you can say “one-time payment” or “pay in full.”
Is choosing 일시불 the same as choosing KRW?
No. 일시불 means paying the purchase in full rather than by installments. KRW is the currency choice that may appear in a separate DCC prompt.
Final Takeaway
Korean card terminals ask about installments because domestic credit cards commonly support monthly payment plans at eligible merchants. For most foreign travelers, the practical response is simple: choose 일시불, confirm the amount in Korean won, and keep the receipt for important purchases.
Once you recognize the words 일시불 and 할부, the checkout process becomes much easier to understand.
