What is a muster roll and does biometric attendance satisfy it?

A muster roll is the daily attendance register that factories and establishments must maintain under Indian labour and wage legislation, showing who was present and their hours. Biometric attendance can be the source for it, and is far harder to dispute than a signature sheet. You remain responsible for maintaining the register in the form your applicable statute requires — AionHRMS provides the underlying per-person daily record it is built from.

Can it handle workers who move between our plants?

Yes. A worker is enrolled once and their template can be pushed to terminals at whichever sites they need access to. Their punches at any of those gates land in the same record.

How do we handle workers whose fingerprints do not scan?

Issue them an RFID card, or enrol them on face recognition if the terminal supports it. Both are recorded as verifications like any other punch, with the method captured, so those workers stay in the register instead of being managed on paper.

Does it calculate wages from attendance?

Yes. Each worker has their own duty times for one or two shifts, punches are assigned to the correct shift, late marks are counted against a grace period you set, and salary is computed from shift units actually present with paid leave applied and late penalties deducted. Advances are recorded and settled against the next payment. What it does not do is file statutory returns — PF, ESI and TDS remain with you or your consultant.

What happens during a power or network cut at the gate?

The terminal keeps verifying workers from its own memory and buffers the punches. When power and connectivity return it pushes the backlog, and the register fills in for the period that was missed.

Factories, sites & contract labour

Attendance management software built around the muster roll

Indian factories and establishments are legally required to maintain a muster roll — a daily record of who was present and for how long. Most do it twice: once in the biometric machine nobody reads, and once on paper because the machine's software cannot produce anything an inspector or a contractor will accept.

Get started Talk to sales

Attendance management software for a factory or site has a different job from office attendance software. The unit is the gate rather than the desk, the workforce includes contract labour who are not on your payroll, and the output has to reconcile with a statutory muster roll and with contractor invoices. AionHRMS captures gate punches from your existing eSSL, ZKTeco or Realtime terminals — including distinct break and overtime events — and keeps a per-person daily record across every gate and every site, so the register and the machine finally agree.

Muster roll

the daily present/absent record Indian wage law expects

Gate-level

multiple entry points per site sharing one worker list

OT & breaks

overtime-in, overtime-out, break-out and break-in as distinct events

Contract labour

temporary workers enrolled and revoked as fast as they change

Why gate attendance is harder than office attendance

An office has one entrance, salaried staff and predictable hours. A plant has several gates, a workforce that turns over weekly, and people who are paid by the shift or by the day rather than by the month. Attendance software designed for offices tends to assume a stable employee list and one reader — both assumptions break immediately on a site.

Several terminals per site, sharing one worker list and one template store
High turnover: enrolling and revoking has to be fast and routine, not a project
Workers who move between sites are enrolled once, not once per gate
Punches carry their terminal, so you can tell which gate someone used

Contract labour, and the invoice argument

The most expensive attendance dispute in Indian manufacturing is not with employees — it is with labour contractors. A contractor invoices for a headcount; the plant believes fewer people actually came. Without a defensible per-person daily record, that argument is settled by whoever is more persistent. Biometric gate attendance settles it with data, provided the data is actually accessible.

Per-person, per-day presence across every gate on the site
Every punch retains its timestamp, terminal and verification method
Contract workers can be enrolled and revoked without touching the payroll list
Access is withdrawn the day an assignment ends, not at the next audit

Worn fingerprints are not an edge case

Manual labour destroys fingerprints. On a real shop floor a meaningful fraction of the workforce will not read reliably on a fingerprint sensor, and the usual result is that those workers are quietly left off the biometric system and marked present on paper — which reintroduces exactly the problem the system was bought to solve.

RFID / proximity cards for workers whose fingerprints do not read
Face recognition where the terminal supports it
The verification method is recorded per punch, so exceptions are visible
Nobody has to be excluded from the register to make the system work

From the gate to the wage sheet

Being precise about this matters more in manufacturing than anywhere else, because a wage calculation that is nearly right is worse than none at all. Attendance does not stop at a report: each worker has their own duty times, punches are assigned to the correct shift, and salary is computed from the shift units actually worked.

One or two shifts per worker, each able to carry its own salary
Late marks counted against a grace period you set, with a threshold before any penalty applies
Penalties as a flat fine or a fraction of a shift's pay — your rule, not a default
Paid leave applied per shift and capped at the month's working days
Advances recorded, tracked and settled against the next payment
Not included: statutory filing. PF, ESI and TDS returns remain with you or your consultant.

Factory attendance: cloud versus the machine's own software

	AionHRMS	Bundled device software
Multiple gates	One worker list and one template store across every terminal.	Frequently one enrolment per device.
High turnover	Enrol and revoke from the browser, same day.	Requires physical access to the terminal.
Multiple sites	Combined view, per-site administrators.	One installation per site.
Contract labour	Managed alongside staff, revoked on assignment end.	Usually handled on paper.
Mixed hardware	eSSL, ZKTeco and Realtime together.	One manufacturer only.
Wage computation	Shift-wise salary from actual punches, with late rules and paid leave.	Varies; often a paid module.
