Discover is a US-based card network that includes the Diners Club network, and it has essentially no local issuance base in Switzerland. This guide is organized from the perspective of a supplementary payment method for holders of cards issued in the US and other countries who visit or reside in Switzerland, a country dense with international organizations and multinational companies.
In Switzerland, Discover is not a primary payment method but a niche complement. With almost no local issuance in Europe, domestic consumer demand is minimal, but there is a steady base of customers using cards issued abroad — international organization and multinational company staff concentrated in Geneva, Zurich, and Basel, as well as American tourists. Through network partnerships with Diners Club, UnionPay, and others, Discover has broad acceptance coverage and serves as a safety net that reduces payment failures for this customer segment.
Hotel, travel, and education service providers with a confirmed share of American customers, or booking businesses targeting English-speaking visitors, can consider adding Discover from a card brand coverage standpoint. If Swiss local consumers make up the main customer base, TWINT and the major card brands are often sufficient on their own.
When a consumer selects a Discover or Diners Club card and enters their card details, the transaction goes through the same approval process as a standard international card, and online transactions may be subject to 3-D Secure-based authentication (equivalent to SCA). The approved CHF amount is collected by Hecto Financial, converted, and settled to the Korean merchant in the contracted currency of USD, KRW, or JPY.
Discover acceptance can be considered on a domestic (Korean) business basis within the scope of Hecto Financial's card network integration. Whether it is supported and the applicable fees and settlement terms vary depending on industry and transaction volume, so a consultation before signing a contract is recommended.

Confirm whether a contract is possible on the basis of a domestic (Korean) business registration
The integration approach and priority vary depending on the composition of online sales channels, such as owned storefronts, open marketplaces, and mobile apps
Advance confirmation is needed as to whether the products fall under industries restricted by Discover's operator merchant policy
Since Switzerland (under FINMA jurisdiction, non-EU) is a market with almost no local Discover issuance, it is worth first checking whether attempted payments from cards issued in the US and elsewhere actually show up in your payment data (see official sources below)
The settlement principle is the same for Discover transactions. Hecto Financial collects and converts the CHF amount, then pays it out in the contracted currency of USD, KRW, or JPY. Because cards issued abroad have different chargeback dispute handling channels and deadlines than domestic cards, it is recommended to confirm the dispute-handling procedures before signing a contract.
Hecto Financial's team will work with you to review the right combination of payment methods for the Swiss market.
