eKYC, or electronic Know Your Customer, is the digital replacement for the paperwork-heavy identity verification process banks and fintechs have relied on for decades. Instead of physical documents and in-person checks, eKYC verifies a customer's identity using digital records — most commonly Aadhaar in India — in real time.
How eKYC Works
In a typical Aadhaar-based eKYC flow, a customer consents to share their Aadhaar details, which are then verified against UIDAI's database using either an OTP sent to the registered mobile number or biometric authentication. The response confirms identity, and in many cases returns demographic details like name, address, and date of birth directly from the source — eliminating manual data entry entirely.
Types of eKYC
- OTP-based eKYC — fast, low-friction, ideal for low-to-medium risk onboarding.
- Biometric eKYC — fingerprint or iris-based, used where stronger identity assurance is required.
- Offline eKYC (XML/QR) — uses a UIDAI-issued offline document instead of a live API call, useful where connectivity is limited.
Why Businesses Are Moving to eKYC
Traditional KYC can take days and requires physical document handling, storage, and manual review. eKYC compresses that into seconds, reduces the cost of onboarding at scale, and produces a verifiable digital audit trail — all while meeting RBI and SEBI compliance requirements for regulated entities.
Where eKYC Is Used
- Bank and fintech account opening
- SIM card activation for telecom operators
- Insurance policy issuance
- Digital lending and credit onboarding
- Gig economy and marketplace seller onboarding
