Accepting e-KYC as an Officially Valid Document enables paperless KYC with biometric authentication for identity and address verification. Authorised Persons may accept physical Aadhaar or UIDAI e-KYC outputs as an Officially Valid Document for identity and, where address matches, for address verification. Use of UIDAI e-KYC requires the individual's explicit consent, biometric authentication, a KYC User Agency agreement with UIDAI, deployment of certified biometric scanners and UIDAI compliant software, and capture of the digitally signed, encrypted demographic data and photograph with a full audit trail. e-Aadhaar downloaded from UIDAI may be printed from the portal or authenticated by UIDAI services as prescribed.
