Overview

Zero Pay is South Korea's public-sector QR-code-based payment service launched by Seoul Metropolitan Government + Ministry of SMEs and Startups (MSS) as a small-business-fee-reduction policy intervention [1, 2, [kr-cro]]. Zero Pay's distinctive feature is 0% commission rate for small businesses with annual sales below KRW 800 million — addressing the SME-burden of card-payment commissions. Zero Pay is accepted at 2+ million businesses including taxis, markets, festivals + integrates with WeChat Pay, UnionPay, Alipay+, PXPay Plus (Taiwan) + other global payment services for cross-border tourist acceptance.

The structural significance: Zero Pay is a government-policy-driven payment intervention — Seoul Metropolitan Government launched it specifically to reduce small-business card-commission burden. The system operates as direct bank-account-to-seller-account transfer triggered by scanning Zero Pay QR + entering payment amount — bypassing card networks entirely. Kakao Pay's announced 2025 integration with Zero Pay marks major adoption milestone — bringing one of Korea's largest fintechs into the government QR ecosystem. Zero Pay's integration with Alipay+ at 1.7M Korean merchants enables outbound Korean-user acceptance at international Alipay+ merchants + inbound international wallet acceptance at Korean merchants. This makes Zero Pay both domestic SME-policy + international tourism-acceptance infrastructure.
