Discover is one of the four major global card networks with the United States as its home market, and unlike other markets, its local issuance base in the US is genuinely large. For merchants in Korea targeting US consumers, it's a card brand worth considering for baseline acceptance alongside Visa and Mastercard.
Discover is a US card business spanning network, issuing, and acquiring, with tens of millions of cards issued in the United States and a loyal user base built around cashback-focused products. It was acquired by Capital One in 2025, reshaping the group, and as a network it has expanded its overseas acceptance footprint through its affiliation with Diners Club International. While it remains only a supplementary brand in overseas markets, within the US it carries genuine payment demand.
Because its customer base is general consumers across the entire United States, it's best approached from the standpoint of 'completeness of US-facing card acceptance' rather than a specific industry vertical. At a checkout that only accepts Visa and Mastercard, payments from Discover-exclusive cardholders or customers who prefer Discover for its cashback benefits can be lost, so the larger a merchant's US sales share, the greater the benefit of closing this acceptance gap.
When a consumer enters their Discover card number at checkout, the issuer's approval process runs, and additional 3-D Secure-based authentication may apply depending on the risk policy. A Discover card registered in a wallet is charged using a tokenized number, so the original card number is never passed to the merchant. Approved funds are received by Hecto Financial in USD, then converted and paid out in the contracted currency.
Through Hecto Financial, businesses incorporated in Korea can explore accepting Discover, and it is typically designed as part of a broader US-facing card payment setup. Because industry restrictions and fee terms vary based on card network rules and contract conditions, preparing data on your US sales volume ahead of discussions with the sales team makes it easier to determine terms.

Discover transaction funds are received by Hecto Financial in USD, then converted and paid out to the merchant in whichever currency (USD, KRW, or JPY) was selected under the contract. Refunds are processed as a reversal to the original card, and since chargebacks are subject to deadlines and evidence requirements set by card network rules, it's advisable to confirm the dispute-handling procedure at the contracting stage.
