Luxembourg is a small domestic market with a population of around 680,000, but a high-income country with among the world's highest per-capita GDP, and because there are not many domestic online shopping options, a large share of consumption happens through overseas online purchases. Since PayPal itself has its European entity (CSSF-licensed) based in this very country and runs its Europe-wide service from there, local recognition and trust are especially high, and it serves as the default wallet that lowers the psychological barrier for Luxembourg consumers accustomed to paying on foreign sites when checking out at an unfamiliar Korean online store.

So even if the share of Luxembourg customers is small, a Korean merchant starting European cross-border sales would do well to consider PayPal as a top-priority method. The effect is especially strong in product categories where consumers are accustomed to buying directly from overseas, such as fashion, hobby goods, and digital content, and in mid-to-high-price categories where buyer protection programs influence conversion.

When a Luxembourg consumer selects PayPal at checkout, they log into their PayPal account and approve with the card or account linked to their wallet; for card-routed payments, PayPal's login and biometric authentication process satisfies the SCA (strong customer authentication) required by PSD2. The approved funds are received by Hecto Financial in euros (EUR) and, after conversion, settled with the Korean merchant in whichever of USD, KRW, or JPY was selected at the time of contracting.

PayPal's European merchant service is operated through its Luxembourg entity, but a Korean merchant can consider integration through Hecto Financial with only a Korean contract. The actual availability and conditions of support (settlement cycle, fees, currency options) vary by industry and transaction volume, so a consultation is needed before contracting.

• Business registration country

  Confirm whether a contract is available under a Korean business registration

• Sales channels

  The integration method and priorities differ depending on your online sales channel mix, such as an owned storefront, open marketplaces, or a mobile app

• Product categories

  Check in advance whether your products fall under a restricted category under PayPal's merchant policies

• EU regulatory compliance

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

Funds from a Luxembourg customer's PayPal payment arise in euros (EUR); Hecto Financial receives them in EUR and, after conversion, settles them with the Korean merchant in whichever single currency among USD, KRW, or JPY was designated at the time of contracting. The settlement cycle follows the contract terms. For refunds, PayPal's buyer protection policy may apply together with the 14-day right of withdrawal guaranteed to EU consumers, so it is safer to spell out the withdrawal procedure in your distance-selling terms.
