Aadhaar Enabled Biometric Attendance System (AEBAS), explained honestly

AEBAS is a Government of India attendance programme. It is different from both a private biometric attendance system and the broader legal framework under which an approved public or private entity may request Aadhaar authentication. This guide keeps those three questions separate.

Get started Talk to sales

The Aadhaar Enabled Biometric Attendance System (AEBAS) is the government attendance programme accessed through attendance.gov.in by onboarded government organisations and institutions. AionHRMS is not AEBAS and does not perform Aadhaar authentication: it is a separate workplace attendance and shift-payroll product using enrolment data held for the customer's own supported terminals. Private entities should not infer from AEBAS eligibility whether they may use Aadhaar authentication for another purpose; UIDAI allows approved government and private requesting entities within its authentication framework, subject to purpose, consent and compliance requirements. Confirm the applicable route with UIDAI, NIC, the parent department and legal counsel before procurement.

What AEBAS is and where it applies

AEBAS was rolled out to bring punctuality and a single attendance record to government offices. Employees register with their Aadhaar number; each day's attendance is marked on a wall-mounted tablet terminal or a desktop fingerprint scanner and verified against Aadhaar in real time; dashboards on attendance.gov.in show presence across departments.

Run by the government for central and state offices and institutions on the programme
Marking requires real-time verification of the employee's biometric against their Aadhaar identity
Organisations onboard through attendance.gov.in with NIC-coordinated registration, and procure devices per the programme's published guidance
Public dashboards are part of the design — attendance transparency is the point

AEBAS onboarding is not Aadhaar authentication eligibility

AEBAS is a government programme, not ordinary attendance software sold off the shelf. Separately, UIDAI's authentication ecosystem can include approved government and private requesting entities. That does not make every employee-attendance use automatically permitted: the entity, purpose, consent, notice, security and other requirements still need to fit the applicable framework.

Government establishments should follow attendance.gov.in, NIC and their parent department's instructions
A private organisation should not claim AEBAS participation merely because it uses biometric attendance
A separate Aadhaar-authentication proposal must be assessed under UIDAI's requesting-entity framework and applicable data-protection law
AionHRMS does not offer Aadhaar authentication and should not be evaluated as an AEBAS terminal

What you actually need instead — and why it is better for you

The searcher who lands here usually wants three things: attendance that cannot be proxy-marked, a register visible to management, and less Excel at month-end. A standard biometric attendance system delivers all three without touching Aadhaar.

The supported terminal verifies locally using its own enrolment format — no Aadhaar number or government database is required by AionHRMS
Punches buffer on supported terminals during a connectivity interruption and upload when connectivity returns
The register is live in any browser, across every branch
The same punches compute shift-wise payroll — the part AEBAS was never designed to do
Raw enrolment payloads are excluded from ordinary reports and the partner API; retention and deletion are handled separately from archiving

If you are a government-adjacent organisation, ask precisely

Some organisations genuinely sit near the boundary — aided institutions, contractors working inside government premises, autonomous bodies. The wrong assumption in either direction is expensive, so resolve it before procuring.

Ask your parent department or NIC coordinator whether AEBAS applies to your establishment
If it does, follow the programme's procurement guidance — AionHRMS is not an AEBAS device vendor and will not pretend otherwise
If it does not, a standard biometric attendance system is the faster, cheaper, payroll-connected path
Contractor workforces inside government sites often need their own private register besides AEBAS — that private register is exactly what we do

AEBAS versus a standard biometric attendance system

	Standard system (AionHRMS)	AEBAS
Who it is for	Private businesses, schools, factories, institutions.	Government offices on the programme.
Identity verified against	Templates enrolled and stored by your own system.	The employee's Aadhaar identity, in real time.
Aadhaar data involved	None.	Central to the design.
Connectivity	Device verifies locally; supported terminals buffer punches during an outage.	Follow the programme's current device and network requirements.
Payroll	Shift-wise salary computed from the same punches.	Attendance only; payroll is separate.
How you get it	Through authorised biometric dealers, one quote.	Government onboarding via attendance.gov.in.

Frequently asked questions

Is AEBAS mandatory for private companies?

AEBAS is a government attendance programme, not a general private-employer requirement or an ordinary software subscription. A private organisation should confirm any sector-specific attendance obligation and separately assess any proposed Aadhaar authentication with UIDAI guidance and legal counsel.

How does a government office register for AEBAS?

Through attendance.gov.in, coordinated with NIC — the organisation is onboarded, nodal officers are designated, employees register with their Aadhaar details, and terminals are procured per the programme's published device guidance. If you are a government establishment, your parent department or NIC coordinator is the authoritative source on the process; a private vendor page is not.

Can AionHRMS connect to AEBAS or use Aadhaar authentication?

No. AionHRMS is not an AEBAS device or Aadhaar authentication service. It records attendance from supported workplace terminals using the customer's own enrolment data, without requiring an Aadhaar number or querying the Aadhaar authentication system.

Does a normal biometric attendance system store Aadhaar or fingerprint images?

AionHRMS does not require Aadhaar for routine attendance. Supported fingerprint terminals normally provide mathematical templates rather than finger photographs. Face devices vary: some provide templates and some supported enrolment or sync workflows use a face photo. Raw enrolment payloads are excluded from ordinary reports and the partner API; see the privacy page for retention details.

We are a school or college — do we need AEBAS?

Government institutions brought onto the programme should follow their department and NIC instructions. Other institutions should confirm their own regulatory requirements rather than assuming AEBAS applies. AionHRMS covers staff attendance and shift payroll, not student attendance or Aadhaar authentication.
