Vietnamese e-commerce, which continues to grow in the 20%-a-year range, is dominated by mobile web and app orders, and Android accounts for the majority of devices. Google Pay offers one-click payment with cards saved by this Android user base, reducing drop-off at the input stage, and it supports both Chrome web checkout and in-app payment. Since card-linked services in Vietnam are still expanding, checking supported card coverage and adopting it alongside local methods is a realistic strategy.

It is recommended first for Korean merchants where shortening checkout time drives revenue, such as mobile games, app services, and subscription content, and for commerce whose main customers are young Android users in Vietnam. To also reach local bank debit card holders, you'll need to combine it with NAPAS cards and MoMo — see the comparison table below.

When a consumer taps the Google Pay button, authentication proceeds with a card saved to their Google account, and a token is passed to the merchant instead of the actual card number. The approved amount is charged in VND, and Hecto Financial receives it locally, then converts and pays out to the Korean merchant in the contracted currency — USD, KRW, or JPY. The range of supported cards and banks in Vietnam requires technical confirmation before integration.

You can consider integration by adding a Google Pay button to your checkout page through Hecto Financial, without needing a separate local contract in Vietnam. The actual scope provided, along with fees, settlement cycle, and currency options, is determined based on merchant screening results.

• 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 Google Pay's restricted-category merchant policies

• Local regulatory compliance

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

The transaction currency for a Google Pay payment is the Vietnamese dong (VND), but the settlement currency paid to the Korean merchant is whichever of USD, KRW, or JPY was set in the contract. Hecto Financial handles local receipt and conversion, and the settlement cycle and fee rate are fixed by the contract terms. Refunds are reversed to the original card used for payment, with the timeline following the issuing bank's standards.
