The first thing to recognize is that Discover has virtually no local issuance base in Belgium. That said, Brussels is an international city that hosts EU institutions and NATO headquarters, drawing a steady inflow of expatriates and business travelers who use cards issued outside the EEA, such as in the United States. This makes accepting Discover, including the Diners Club network, meaningful as a complementary option to avoid missing this minority customer segment.

It is worth accepting if you run a service business with a meaningful share of foreign visitors, such as hotels or tours, or an industry with a mix of offshore customer payments, such as international schools or language programs. If your goal is revenue from local Belgian consumers, it makes more sense to review the Bancontact or wallet pages before this one.

The payment flow mirrors that of standard card networks: the consumer enters their Discover or Diners Club card details, and approval is granted through the international network. Since most cards are not EEA-issued, EU SCA (Strong Customer Authentication) requirements may apply differently depending on the issuer's location, and it is advisable to design fraud detection rules that account for the nature of foreign-issued cards. Approved funds are received by Hecto Financial in euros.

Integrating through Hecto Financial lets a Korean corporation consider accepting Discover and Diners Club cards without a separate local contract in Belgium. Because transactions are centered on foreign-issued cards, fraud prevention policy and fee terms should be confirmed together, and actual coverage varies by industry and transaction volume.

• Business registration country

  Confirm whether a contract is possible on the basis of a Korean business entity

• Sales channels

  The integration method and priority differ depending on your online sales channel mix, such as your own mall, open marketplaces, or mobile apps

• Product categories

  Advance confirmation is needed as to whether your category falls under restricted industries per the Discover operator's merchant policy

• EU regulatory compliance

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

Even when paid with a foreign-issued card, the transaction currency is the euro (EUR). Hecto Financial receives these funds, converts them, and settles them to the Korean merchant in USD, KRW, or JPY as specified in the contract. The settlement cycle follows the contract terms. Refunds follow the original-card-refund principle, and even if the cardholder resides outside the EEA, if the transaction is a remote sale shipped to Belgium, it is advisable to take a conservative view on whether the EU's 14-day withdrawal rule applies and set a broad refund policy to prevent disputes.
