Why this matters now

## Why KYC is the compliance backbone for digital lending

01

### Fraudulent apps drew RBI attention

Sham digital lending apps and harassment by unlawful lenders triggered targeted RBI action. Rigorous KYC has moved from competitive advantage to regulatory baseline.

02

### Aadhaar regulation keeps moving

The 2018 judgment, the 2019 Finance Ministry circular, the 2021 RBI notification, the 2022 CERSAI rectification window — lenders that stopped tracking after Aadhaar's quash are working off stale rules.

03

### Outsourcing concentrates risk

RBI views fintech-as-tech-provider arrangements as exposing lenders to financial, operational, and reputational risk. The compliance burden sits with the regulated entity, not the fintech.

What the rules actually say

## Three things lenders get wrong about KYC

Insight 01

### Decision-making cannot be outsourced

RBI is explicit: regulated entities cannot outsource the decision on KYC compliance. The fintech's role is operational; the call sits with the lender. Most fintech-bank arrangements miss this until an audit catches it.

Insight 02

### C-KYC has a rectification window now

Until 2022, a CERSAI record was treated as final. The new rectification provision lets lenders request corrections to misstated customer particulars during audits — which means lenders should now actively use it instead of accepting bad records.

Insight 03

### Periodic updation has timing rules

High-risk customers re-KYC every 2 years, medium 8, low 10\. The cycle must be digitised but personalised — no-change confirmation, address change, status change (minor to adult). Bulk re-KYC campaigns ignore the cycle and burn customer trust.

How to attempt KYC

## The KYC cascade

C-KYC first, then offline e-KYC, then online or video. Following the cascade reduces friction, drop-offs, and ops cost without compromising compliance.

STEP 01 C-KYC When the customer is already in CERSAI Authorise lookup of stored documents from the central registry — lowest friction. STEP 02 Offline e-KYC When CERSAI has no record Customer-initiated XML upload or QR scan of Aadhaar — no Aadhaar number ever held. STEP 03 Online e-KYC / V-CIP When the cascade above does not work OTP or biometric via KUA license, or live video session — most resource-intensive. Lowest friction → highest friction

What's covered

## What this guide walks through

KYC has moved from a one-time onboarding step into the compliance backbone of Indian digital lending. The 2018 Aadhaar judgment, the 2021 RBI circular on KUA licenses, the 2022 CERSAI rectification window — each shifted what is permitted. This guide walks through the four KYC methods, the regulatory entanglement with Aadhaar, the data-storage rules, and the operating model that lets fintechs build responsibly.

01

**The four KYC methods**Physical, Video (V-CIP), Aadhaar e-KYC (online OTP/biometric and offline XML/QR), and C-KYC — what each requires, when each works, and where regulation has shifted.

02

**Aadhaar after the 2018 judgment**What Section 57 quashed, what the RBI's 2021 KUA-license circular permits, and the workarounds non-banks now use without holding the Aadhaar number itself.

03

**Storing and processing Aadhaar data**The Aadhaar Data Vault rules, encryption requirements for scanned copies, and the SPDI Rules every lender's processing pipeline must conform to.

04

**The KYC cascade**C-KYC, then offline e-KYC (XML/QR), then online e-KYC or video — the preferred order, why it minimises friction, and where it breaks for thin-file customers.

05

**Building a responsible KYC programme**UI/UX patterns that keep drop-offs low, periodic updation cycles (2/8/10 years for high/medium/low-risk customers), automation, and the outsourcing rules every fintech-bank partnership runs into.
