The Aadhaar Enabled Biometric Attendance System was launched by the Government of India in 2014 as part of the Digital India initiative, to promote transparency and punctuality in government offices. The AadhaarBAS mobile application, developed by the National Informatics Centre, enables registered government employees to seamlessly mark their daily attendance.
The app is exclusively for government officers and employees enrolled on the central attendance portal and is not available for the general public. Initially, attendance was captured through fingerprint or iris authentication devices, matched in real time with UIDAI’s Central Identities Data Repository (CIDR). To meet evolving requirements, the AEBAS team has integrated Face Authentication using UIDAI’s Aadhaar Face RD service, offering employees a faster, touch-free, and highly secure mode of marking attendance.
In practice, an employee simply enters their attendance ID and verifies identity through biometric or face authentication. The system responds in 2–3 seconds, recording both check-in and check-out seamlessly. This innovation has enhanced user convenience while maintaining robust security.
The AadhaarBAS app is a secure, India-only platform that exemplifies how Aadhaar authentication can support efficient governance, transparency, and accountability in public service.
