France has a sizable resident Chinese-speaking population—students and expatriates—in addition to tourists, and since their daily communication happens on WeChat, the path from browsing to payment within WeChat flows naturally. WeChat Pay is Tencent's service, which together with Alipay splits China's mobile payment market, and its defining feature is the ability to complete everything from product discovery to payment inside the WeChat ecosystem, via mini-programs and official accounts.

For merchants that communicate and sell to Chinese-speaking customers through the WeChat channel—Chinese-market-focused commerce, services aimed at international students, travel-linked products—completing the entire purchase inside WeChat is advantageous for conversion. This should be designed as a separate track from targeting general French consumers.

The transaction is completed when a consumer scans a QR code in the WeChat app or approves payment via a mini-program or in-app checkout. Even though the consumer pays in yuan, the merchant transaction is processed in the local currency—a cross-border structure—and selling within the WeChat ecosystem (mini-programs) uses a different integration method from external web checkout, so technical requirements need to be confirmed once the channel is decided.

Through Hecto Financial, Korean merchants can look into accepting WeChat Pay cross-border. The scope of integration varies depending on whether you operate a WeChat official account or mini-program, so it is efficient to consult together with your channel strategy.

For WeChat Pay transactions in France, Hecto Financial receives the payment in euros (EUR), converts it, and settles to Korean merchants in whichever currency—USD, KRW, or JPY—was chosen in the contract. The settlement cycle follows the contract terms. For transactions involving EU consumers, you also need to prepare a refund process aligned with local consumer protection rules, including the 14-day withdrawal right.
