Online spending in Vietnam is growing more than 20% a year, and payment demand from tourists and business visitors is also rising. Most local consumers use NAPAS cards or e-wallets, but for a business with a mix of customers using U.S.-issued cards, accepting Discover acts as a safety net that reduces payment failures. Discover is a U.S. card network that has expanded its acceptance footprint across Asia through mutual acceptance agreements with networks like Diners Club and UnionPay.

It's well suited as a complementary method for services aimed at foreign residents in Vietnam or customers from the Americas, and for travel, accommodation, and airline booking commerce with a share of internationally issued card payments. If the local mass market is your main focus, adoption priority is lower — we recommend establishing local methods like MoMo and NAPAS first, then considering Discover as a coverage extension.

When a consumer enters their Discover card number and passes card issuer authentication, approval goes through the international card network. Hecto Financial receives the Vietnamese transaction amount in local currency, converts it, and settles with the Korean merchant in whichever currency was set in the contract — USD, KRW, or JPY. The card approval routing and fee structure should be confirmed before integration.

Discover acceptance is reviewed within the scope of Hecto Financial's card network integration, and a Korea-based entity can proceed without a separate local contract. Approved industries, fees, and settlement cycle and currency options vary by transaction characteristics and need to be confirmed before signing.

• Business registration country

  Confirm contract eligibility as a Korea-registered business

• Sales channels

  Integration method differs depending on whether you are online-only or also have physical stores in Vietnam

• Product categories

  Check in advance whether your products fall under Discover's restricted-category merchant policies

• Local regulatory compliance

  Confirm compliance with Vietnam's payment and foreign exchange regulations (see official sources below)

From the consumer's perspective, a Discover payment is also a VND transaction, and the Korean merchant does not receive VND directly. Hecto Financial converts the received amount and pays out in whichever currency was contracted — USD, KRW, or JPY — with the cycle and fees varying by contract terms. Refunds and chargebacks follow international card network rules, so familiarize yourself with dispute-response procedures in advance.
