The Aadhaar System is built on a sound strategy and a strong technology backbone and has evolved into a vital digital identity infrastructure. Aadhaar, being a unique digital ID – provides a powerful platform for authenticating a resident anytime and anywhere which is in line with the vision of the UIDAI. The purpose of Authentication is to enable residents to prove their identity and for service providers to confirm that the residents are ‘who they say they are' in order to supply services and give access to benefits.
Enrolment & Update Ecosystem

Enrolment Agencies are appointed by Registrars and are responsible for collecting demographic and biometric information of individuals during the enrolment process by engaging certified Operators/Supervisors.
