Discover is a method aimed less at local Hong Kong consumers and more at customers holding cards issued abroad, mainly in the United States. For businesses with a share of international customers, this page covers the payment flow and settlement structure when accepting the Discover Global Network.
As an international financial hub, Hong Kong sees frequent tourism, business travel, and transactions from overseas residents, so the share of the payment market held by cards issued abroad is not negligible. Discover is a US-based card network operated by Discover Financial Services, with Diners Club under its umbrella and mutual acceptance partnerships with networks such as UnionPay and BC Card. That said, the base of cards issued locally in Hong Kong is limited, so it is more accurate to view it not as a primary method for local consumers but as a complementary channel for accepting cards issued in places like the United States.
This is valuable for businesses that receive a mix of orders from US-resident customers or foreigners staying in Hong Kong. For commerce that supports global shipping, or booking and service businesses with a share of English-speaking customers, adding the Discover family (including Diners) alongside Visa and Mastercard can reduce revenue lost to card declines.
As with standard card payments, the consumer enters their Discover or Diners card number at checkout, or pays with a saved card, and authorization and acquiring are processed via the Discover Global Network. Proceeds from transactions into Hong Kong are received by Hecto Financial in HKD, and after conversion, settled to the Korean merchant in the currency chosen at contract signing from USD, KRW, or JPY. Whether fraud-prevention options such as 3-D Secure apply should be confirmed against technical documentation before integration.
Accepting the Discover network is handled together within the scope of Hecto Financial's international card payment integration, so a Korea-based corporation does not need to sign a separate contract with Discover itself or a local acquirer in Hong Kong. Fee rates and support terms by card brand are calculated differently by industry and transaction volume, so confirm the applicable scope with Hecto Financial's sales team before signing a contract.

Payment proceeds from Discover transactions are first received by Hecto Financial in the local currency, HKD. They are then converted at the time of merchant settlement and paid out in the currency designated in the contract from USD, KRW, or JPY, with the settlement cycle and fee rate set according to the contract terms. Refunds and chargebacks follow the dispute-handling rules of the international card network, so it is advisable to review the processing deadline, evidence requirements, and exchange rate basis together at the contracting stage.
