The Aadhaar (UIDAI) sandbox for digital identity and finance innovation

The Unique Identification Authority of India (UIDAI) launched a regulatory sandbox in 2023 to plug a critical gap: FinTechs and start-ups had no safe, cost-effective way to integrate core Aadhaar APIs and validate e-KYC or authentication journeys before going live. The sandbox offers that controlled environment, accelerating new use cases in digital identity, financial services, and authentication, and supporting India’s broader digital-financial-inclusion strategy.

Commissioned by the Gates Foundation, MSC designed the sandbox end-to-end—drafting operational guidelines, eligibility and evaluation criteria, and outreach plans—then set up the cohort-management process and provided hands-on technical support so shortlisted FinTechs could refine biometric-authentication flows and KYC models.

In its first year, the sandbox attracted 150+ applications, selected 15 high-potential start-ups across two cohorts, and facilitated more than 1 million test authentications, helping participants cut average product-validation time by ~40 percent (UIDAI monitoring data, May 2025). These pilots have already produced paperless KYC stacks, contactless biometric-auth solutions, and AI-driven credit-scoring models, now moving toward market launch.
