Instant KYC and Onboarding: Redefining Fintech Verification with Multimodal WebRTC

The Compliance Landscape

In India, digital user onboarding (KYC) faces high dropout rates due to clunky video calls and manual document uploads. Vanira Real-Time AI integrates real-time document intelligence directly into standard WebRTC connections. This allows fintechs to scan Aadhaar/PAN cards, perform face matching, and verify identity within a single, continuous call for under ₹20.

Know Your Customer (KYC) regulation is the bedrock of modern financial services. Yet, the onboarding experience remains a massive point of friction. Consumers regularly drop off when asked to jump between uploading PDF files, verifying SMS OTPs, and waiting for video verification agents to become free.

Vanira resolves this by executing local edge-based features: face tracking, liveness verification, and text parsing are compiled into a sandboxed WASM library that runs directly inside the customer’s browser. Only high-confidence, encrypted keyframes are sent to domestic compliance databases for matching. This local-first structure ensures zero data leakage and absolute security.

The Paradigm Shift: User Onboarding

Before Vanira

  • High Dropout Rate: Forcing users to wait in queues for live agents to review their documents via video call.
  • Expensive Agent Ops: Traditional video-KYC vendors charge ₹40 to ₹100 per successful user verification.

After Vanira

  • Zero-Latency Scanner: Instant automated document OCR extraction and facial matching on live WebRTC stream.
  • Fractions of Cost: Complete compliance-grade identity validation runs for less than 20 rupees (₹20) per call.

How Onboarding Verification Works

1. Sandboxed Document Scan

Extracts Aadhaar/PAN fields locally using optimized edge OCR models.

2. Edge Liveness Check

Verifies structural features and user presence directly inside the browser sandbox.

3. Vanira Match

Matches verification payloads against domestic compliance vaults securely.

Secure Local Processing for Maximum Trust

In India, RBI regulations require strict controls over customer biometric data. Shipping unencrypted video streams to foreign public cloud APIs violates data sovereignty rules.

Vanira resolves this by executing local edge-based features: face tracking, liveness verification, and text parsing are compiled into a sandboxed WASM library that runs directly inside the customer’s browser. Only high-confidence, encrypted keyframes are sent to domestic compliance databases for matching. This local-first structure ensures zero data leakage and absolute security.
