Cards held by local Danish consumers are centered on Dankort (Visa co-badged) and international-brand debit and credit cards, and Discover cards are rarely issued locally. So real demand for this method comes from customers holding foreign-issued Discover or Diners Club cards, such as American tourists, business travelers, and expatriates visiting Copenhagen. It is not a primary method for the Danish market but a method aimed at broadening the range of cards you can accept.

Merchants where foreign-issued cards frequently appear—hotel and tour bookings with a share of American customers, or international event registration desks—may find it worth adding to reduce declined authorizations. If your goal is commerce aimed at local Danish consumers, the order to follow first is putting Dankort, MobilePay, and international card networks in place first.

Payments with foreign-issued Discover or Diners Club cards follow the same flow as a standard card payment, and transactions within Europe are subject to PSD2 SCA (3DS authentication) requirements. Hecto Financial collects the approved amount in DKK, converts it, and settles it to the Korean merchant in the contracted currency—USD, KRW, or JPY.

Consistent with its position as a complement for foreign-issued cards, Hecto Financial provides guidance for adding Discover and Diners Club acceptance on top of your existing card network integration. Whether adoption is possible for a Korea-registered business, along with fees and settlement terms, varies by industry and transaction volume.

• Business registration country

  Confirm contract eligibility as a business registered in Korea

• Sales channels

  Integration method and priority vary depending on your online sales channel mix—owned store, open marketplaces, mobile app, etc.

• Product categories

  You need to check in advance whether your products fall under categories restricted by Discover's operator merchant policy

• EU regulatory compliance

  Confirm compliance with EU payment regulations such as PSD2 and SEPA (see official sources below)

Discover transaction proceeds are also collected in DKK and then converted before being settled in the currency selected in the contract—USD, KRW, or JPY. Because foreign-issued cards can make disputes and chargebacks take longer to resolve, keep a system for retaining transaction evidence, and manage sales to EU consumers separately, bearing in mind that intra-EU rules such as the 14-day right of withdrawal apply to them.
