Frequently asked questions

Key information about adopting Diners Club payments

QCan I adopt Diners Club payments without an overseas entity?

QHow is Diners Club different from other card networks?
Diners Club is the world's first credit card brand, launched in 1950, with a merchant network spanning more than 190 countries. It has a long tradition as a business card issued for corporate travel and entertainment purposes, and it gained an even more stable infrastructure after Capital One's 2025 acquisition of Discover.
QWhat is the relationship between Diners Club and Discover?
Diners Club has been operated by Discover Financial Services since 2008, and when Capital One acquired Discover in May 2025, the Diners Club brand was also brought under the Capital One group.
QHow much is the payment fee?
Merchant fees vary depending on the transaction country, payment type (domestic vs. overseas), and payment gateway contract, and are generally set at typical international card payment fee levels. When integrating through Hecto Financial, fees are negotiated separately based on transaction volume.
QCan an online-only store also adopt this?

QWhat currency is used for settlement?
Customers pay in the currency linked to their card, and after Hecto Financial receives and converts the overseas payment funds, settlement to the Korean merchant is made in USD, KRW, or JPY as selected in the contract. The settlement cycle and exchange rate basis follow the contract terms.
QCan I integrate other card networks (Visa, JCB, etc.) as well?
Yes. In addition to Diners Club, Hecto Financial supports major global card networks such as Visa, Mastercard, American Express, UnionPay, and JCB, and can also manage various country-specific local payment methods such as PayPay and Rakuten Pay under a single integrated contract.
