Frequently asked questions
Key information about adopting Mastercard payments
QCan I adopt Mastercard payments without an overseas entity?
Yes. Integrating through Hecto Financial lets you adopt Mastercard payments without an overseas entity or overseas bank account.
QHow is Mastercard different from other card networks?
Mastercard is the world's No. 2 card network, accepted at over 110 million merchants in more than 210 countries. It holds a particularly strong position in some European countries and across Latin America, complementing Visa well.
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?
Yes. Hecto Financial's global payment service is provided for online (web/app) payments, so you can adopt it even if you only operate online sales channels such as your own store, an open marketplace, or a mobile app. It integrates into web and app checkout via a payment window or API.
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 Mastercard, Hecto Financial supports major global card networks such as Visa, American Express, UnionPay, JCB, and Diners Club, and can also manage various country-specific local payment methods such as PayPay and Rakuten Pay under a single integrated contract.
