Discover is a US-based card network linked to the Diners Club network, with almost no local issuance base in Europe, including France. In the French market it should therefore be approached not as a primary method but as a complementary one, to avoid losing payments from visitors and expatriates carrying cards issued abroad, such as in the United States.
France is one of the world's leading tourism destinations with a steady inflow of American visitors and international expatriates, but local payment defaults to the CB card, and Discover has virtually no issuance base within France. The value of accepting Discover isn't about reaching French consumers — it's about preventing declined payments from customers holding cards issued abroad in the Discover or Diners Club family.
It has a complementary effect for merchants that actually see traffic from cards issued abroad — tourism and hospitality-linked commerce, global sales sites with a meaningful share of American customers, and services aimed at expatriates or international students. It's not too late to decide after checking the decline rate for foreign-issued cards in your own payment data.
Holders of Discover or Diners Club cards pay by entering card details just as with a standard card payment, and even a foreign-issued card can be subject to authentication under PSD2's SCA policy for transactions with a merchant based in the EU. Whether the network is accepted depends on the integration configuration, so this should be confirmed in advance.
We recommend reviewing together whether the Discover network can be included within Hecto Financial's card acceptance scope, and whether it offers real value given your merchant's customer mix. Coverage of local French customers is handled by CB, Visa, and Mastercard, so the roles are clearly divided.

Discover transactions arising in France are also processed as euro (EUR) funds, received by Hecto Financial and, after conversion, settled in whichever of USD, KRW, or JPY is selected in the contract. The settlement cycle follows the contract terms, and refunds are processed as a cancellation of the original transaction. If you are selling to consumers within the EU, handling the 14-day withdrawal right works the same way as for other cards.
Hecto Financial's team will help you review the right combination of payment methods for the French market.
