The primary full form of eKYC is Electronic Know Your Customer. In digital banking, telecommunications, and financial technology (Fintech), eKYC is a paperless, automated digital identity verification process that allows banks, mutual funds, stockbrokers, and telecom operators to verify the authentic identity and residential address of a customer electronically using government identity databases such as Aadhaar (UIDAI).

How does Aadhaar eKYC work in India?
1. Consent and credential submission
The customer initiates an online account opening process (such as opening a Demat account or digital bank account) and enters their 12-digit Aadhaar number or 16-digit Virtual ID (VID), providing explicit legal consent for identity lookup.
2. Multi-factor authentication
UIDAI verifies the request using one of two digital channels:
- OTP Authentication: A one-time password (OTP) is sent instantly to the mobile number registered with the customer's Aadhaar card.
- Biometric Authentication: The customer places their finger on a certified biometric scanner or looks into an iris reader at a retail banking branch or telecom kiosk.
3. Encrypted electronic packet transfer
Upon successful validation, UIDAI's central servers release a digitally signed, tamper-evident XML or JSON data packet containing the customer's verified demographic data: full legal name, date of birth, gender, address, and high-resolution photograph.
4. Automated account onboarding
The financial institution ingests the cryptographically signed data packet, confirms that the credentials match government registries, and activates the customer's bank account or SIM card instantly.
