South Korean Cards

2024-12-19 08:05

Credit cards have been a common payment method in South Korea since the 1960s, and remain the preferred payment method today, accounting for more than 50% of the online e-commerce payment volume. In a country where 95% of the population holds bank accounts and a credit card penetration rate surpasses 60%, accepting South Korean card payments enables you to reach nearly the entire population of over 50 million.

Supported card brands

In contrast to international cards, the majority of South Korea's local cards are issued by nine primary companies. Prominent brands include Shinhan, BC, Samsung, KB, Hyundai, Lotte, NH, Hana, and Woori. Of the over 110 million cards issued locally, single-badged cards account for around 45%, while co-badged cards, which also display international card scheme logos, make up approximately 55%. Antom's solution supports both single-badged and co-badged local cards.

The following are all supported South Korean local card brands:

Shinhan Card, Hyundai Card, Samsung Card, Lotte Card, Hana Card, KB Kookmin Card, BC Card, NH Nonghyup Card, Woori Card, IBK B.C., Gwangju Bank, KDB Industrial Bank, Saemaeul Geumgo, Shinhyeop, Citi Card, Post office deposit insurance, Korea Federation of Savings Banks, Jeonbuk Bank, Jeju Bank, Kakao Bank, K Bank, Toss Bank, SH Suhyup Bank.

User experience

Note: The following payment flows on different terminals are reference only, and represent this payment method's flow on different terminal types. For supported merchants' terminal types, consult Antom Technical Support.

Antom offers two types of payment flows for South Korean Cards:

Issuer-authentication payment: Users are redirected to the bank page of the chosen issuer to complete the payment. Payment is completed via different processes, such as scanning a QR code, or inputting card or bank account information, depending on the particular bank's capabilities. You are required to provide these payment flows for merchant industries such as gaming and top-up services.
Non-authentication payment (Key-in): Users need to manually key in their card details as per the typical international card payment process.

Note: For South Korean Cards-installment function, merchants can design how to show 2-12 installments for users, or merchants can redirect users to Ant's middle page for users to choose 2-12 installments. When users choose a specific installment plan, the common practice in the Korean market is that merchants do not show users the corresponding plan's interest rate on the checkout page. Instead, Korean users can check their interest fees on the card issuers' monthly bills or statements.

The following figures show the journey of paying with South Korean Cards in different scenarios.

Period: 12/01/2024 ~ 12/31/2024 Even if “FREE Installment” is displayed on the payment window, excluded cards and industries are not eligible. Depending on the card issuer's policy, debit, prepaid, and gift cards may be excluded from interest-free installments. In cases of NH Nonghyup Card's if the benefits from "Interest-Free Installment" and "Partial Interest-Free Installment" can be both applied, more beneficial one would be applied. Corporate/business/check/prepaid/gift/hybrid cards, and some bank-affiliated BC cards may be excluded. BC card covers personal credit payments for Woori, IBK, NH, SC, Daegu, Busan, Gyeongnam, Shinhan, Hana, KB, Citi BC(excluding Citi Visa), and Suhyup. For interest-free payments from other issuers, inquiries should be made to the individual issuer. Suhyup BC has been eligible for BC Card's "Interest-Free Installment" since 03/01/2024. However, Suhyup BC is excluded from BC Card's "Partial Interest-Free Installment." For cards issued by Citi card, "Interest-Free Installment" will not be provided in 2024. For Citibank BC cards, "Interest-Free Installment" will be provided according to the policies of BC cards. Interest-free benefits are provided for e-commerce PG industries. However, benefits may be restricted for other industries (such as vouchers, refunds, medicine, pharmaceuticals, academies, duty-free shops, insurance, car rentals, airlines, local tax payments, etc.). Some merchants directly contracted with card issuer, new merchants, public institutions, and certain offline payments are excluded from eligibility. However, Paynow Biz are eligible for interest-free installment. This event may change or discontinue depending on the card issuer’s decision.

Note: These information will be updated monthly and might change according to each card issuer's own policy.
