Online payments in the Czech Republic are led by cards and bank transfers, and the card networks are effectively all Visa and Mastercard. Discover, an American card brand that connects through the Diners Club network, has almost no local issuance base in the Czech Republic, so it should be approached not as a way to target local consumers but as a supplement for capturing payments from tourists, business travelers, and expatriates who hold cards issued abroad, such as in the United States.

For businesses whose actual logs show payment attempts with foreign-issued cards — Prague-centered tourism demand, or accommodation, tours, and global digital services with a mix of English-speaking customers — accepting it can reduce declined authorizations. On the other hand, if you serve only domestic Czech customers, the priority should be to first put Visa/Mastercard-family cards and bank transfer methods in place.

When a consumer enters a card number or pays with a saved card, authorization runs through the Discover network, and for transactions within the EU, additional 3DS-based authentication may apply under PSD2's Strong Customer Authentication (SCA) requirement. Hecto Financial receives the approved funds, converts them, and settles to the Korean merchant in whichever currency — USD, KRW, or JPY — was selected under the contract.

Through Hecto Financial, you can consider accepting Discover and Diners Club cards as an addition to your existing card integration, without a separate local contract in the Czech Republic. That said, because of its nature as a supplementary method, terms may vary depending on expected transaction volume, so this should be confirmed through a consultation before contracting.

• Business registration country

  Confirm contract eligibility based on domestic business registration

• Sales channel

  The integration method and priority vary depending on your online sales channel mix — owned mall, open marketplace, mobile app, and so on

• Product category

  Check in advance whether your products fall under categories restricted by Discover's merchant policy

• EU regulatory compliance

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

Settlement follows a "receive locally, then convert" structure. Whatever currency is displayed at the time of payment, Hecto Financial receives and converts the funds and pays the Korean merchant in a single selected currency — USD, KRW, or JPY — with the cycle and fees following the contract terms. Given the nature of foreign-issued cards, dispute (chargeback) processing deadlines may differ from those for domestic cards, and for sales to EU consumers, the refund obligation arising from the 14-day right of withdrawal should also be factored in.
