Spain has a high share of Android smartphones even within Europe, so the Google Pay button offers broad effective coverage in mobile commerce. Because payment itself runs on top of a market structure where card is standard, it is accurate to understand Google Pay as a conversion device that lets shoppers use a saved card without re-entering it, and as a method that reduces PSD2 SCA friction through device authentication.

It is particularly effective for mid-to-low-price commerce with a high share of mobile web traffic, and for businesses selling app-based services, games, and subscription products. It is common to pair it with Apple Pay for iOS customers to align the payment experience across devices, while account-transfer-type demand is handled separately by Bizum and the SEPA family.

When a consumer taps the Google Pay button, the card stored on their device is passed as a token (virtual account number), and device unlock and biometric authentication serve as the PSD2 Strong Customer Authentication (SCA) component. The approved payment is recorded in euros (EUR), just like a card transaction, and Hecto Financial collects it, converts it, and settles it with the Korean merchant.

Google Pay is a method whose activation is reviewed as an extension of an existing card acceptance contract, and a Korean corporation can consider integration through Hecto Financial. Actual eligibility and detailed terms vary by merchant industry and transaction volume, so confirmation with the sales team before contracting is recommended.

• Business registration country

  Confirm contract eligibility based on domestic business registration

• Sales channels

  The integration approach and priority differ depending on your online sales channel mix, such as your own site, open marketplaces, and mobile apps

• Product categories

  Check in advance whether your category falls under restricted industries per Google Pay's merchant policy

• EU regulatory compliance

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

Hecto Financial collects Google Pay revenue in euros (EUR) and, after conversion, pays the Korean merchant in whichever currency — USD, KRW, or JPY — was specified in the contract. Refunds are processed as cancellations of the original card transaction, so no separate channel is needed, and 14-day right-of-withdrawal refunds for EU customers, including those in Spain, can be handled through the same route.
