Research Methodology

Demand-side practitioners and supply-side operators were both consulted through structured primary interviews with payment engineers at fintech developers, platform architects at super-app operators, treasury automation leads at logistics enterprises, and merchant acquisition heads at retail chains. Secondary validation drew from Financial Services Commission regulatory filings, Bank of Korea payment system statistics, open banking API documentation, and hyperscaler cloud service disclosures. Bottom-up transaction volume modeling triangulated against top-down infrastructure capacity assessments.

Across the projection horizon, the analytical framework segmented volume and value outputs by payment method, transaction type, platform architecture, and user segment, with CAGRs derived from trend extrapolation of open banking adoption curves and mobile wallet penetration rates. Forecast inputs incorporated ISO 20022 migration timelines and central bank digital currency pilot expansion scenarios without assuming specific commercialization dates.

The analysis sits within stated boundaries; outcomes outside sustained regulatory support for open banking interoperability or accelerated legacy system modernization would require recalibration. Practitioners should keep alternative scenarios live as Financial Services Commission API governance standards and Personal Information Protection Commission consent frameworks evolve.
