End to end
One shop from the machine on the wall to the salary sheet
Most biometric purchases are three vendors pointing at each other: a hardware dealer, a software company and whoever does payroll. Here it is one chain with one party answerable at every link.
01
The machine
A fingerprint, face or RFID terminal supplied by an authorised dealer near you — or the eSSL, ZKTeco or Realtime machine already on your wall, repointed instead of replaced.
Choosing a machine02
Installation
Mounting, wiring, power and network are handled by a local dealer under the visit terms written into your quote.
Our dealer network03
Cloud software
The terminal pushes each punch to AionHRMS. Create employee profiles in the browser, use model-compatible enrolment workflows, control access, and read the register from anywhere.
The software04
Payroll
The same punches compute the salary: per-employee shifts, grace periods, late penalties, paid leave and advances — a figure, not an export.
Attendance to salary05
One accountable partner
One quote and one responsible dealer for the hardware, with the software engineered and supported by AIONDATA's team in Noida. No vendor triangle when something breaks.

Attendance
Everything the free software should have done
Two implemented protocol families
Supported iClock/ADMS terminals from eSSL, ZKTeco and other vendors, plus supported Realtime terminals using its native protocol, can report into the same attendance register. Compatibility is confirmed by exact model, protocol and firmware before deployment.
Cloud enrolment pushed to the device
Create an employee in the browser and push the record to every terminal at that site. No keypad entry at the machine.
Model-specific enrolment distribution
Employee profiles can be pushed from the browser. Biometric reuse depends on format: compatible iClock templates can be re-pushed to compatible iClock terminals, TIMY face photos sync only within TIMY, and Realtime devices require device-side biometric enrolment. The exact workflow is confirmed per model and firmware.
Break and overtime as distinct events
break-out, break-in, overtime-in and overtime-out are recorded as their own event types, not inferred from gaps between punches.
Access control, not just a timesheet
Lock or unlock any employee from the dashboard; the instruction reaches every terminal at that site. Denied attempts are recorded. Doors can be released remotely.
Verification method on every punch
Each record keeps which method verified it — face, finger, card or PIN — which is what settles a disputed entry.
Payroll
Attendance that carries all the way to salary
Most attendance products stop at a report and leave you to re-key it into a spreadsheet. The punch that opened the gate is the same punch that decides the salary — no export, no reconciliation, no second version of the truth.
Single or double shift per employee
Each person has their own duty times. Punches are bucketed to the correct shift automatically, and a double-shift employee can carry a separate salary for each shift.
Late marking with a grace period
A configurable grace window decides what counts as late. Late marking is disabled entirely for staff with no saved duty time, so nobody is penalised against a default they never agreed to.
Late penalties you define
Set how many lates trigger a penalty, and whether the penalty is a flat fine or a fraction of a shift's pay. Below the threshold, nothing is deducted.
Paid leave that behaves correctly
Paid leaves are allowed per shift and capped at the month's working days, so full attendance always pays exactly the configured salary — in a 28-day February and a 31-day March alike.
Salary computed from actual attendance
Gross is derived from shift units present, then late deductions are applied, giving a calculated amount per employee per month. The breakdown is itemised rather than a single number.
Advances tracked and settled
Record a salary advance, see the outstanding balance, and settle it against a future payment. The advance is booked to expenses at the same time.
Monthly payroll report
One report across all staff for a month, plus a per-employee attendance calendar showing every day's status.
PF and TDS deductions, off by default
Once a company switches them on, payroll splits basic salary, works out employee and employer PF (wage ceiling applied by default) and new-regime TDS, and shows both on the payslip. Returns are not filed by the software, and ESI is not computed.
Comp-off and leave rules by department
Working a weekly off or a holiday can be claimed back as a comp-off day, once the company switches comp-off on. Weekly offs, holidays and leave quotas can follow the company, a department or one employee.
In practice
Six moments the system is built for
Feature lists all read the same. Here is what actually happens on the days that test an attendance system.
01
Day one at a new site
The dealer mounts the terminal and points it at our server from its own menu. You import the staff list in the browser and push it to the device. Enrolment runs at the gate; by evening the register is live.
02
The 09:00 rush
Face and fingerprint matching happens on the terminal; throughput depends on the selected model, firmware and entrance conditions. HR watches accepted punches land in the register from a browser, at the site or three cities away.
03
A resignation at 5 p.m.
HR blocks the employee from the dashboard. Every terminal at the site gets the instruction — by the time the paperwork is filed, the door no longer opens for them. Their attendance history stays intact.
04
Month-end, without the spreadsheet
Punches are already bucketed to each person's shifts, grace periods applied, late penalties counted. Payroll is a computed figure per employee with paid leave and advances settled — reviewed, not rebuilt.
05
The inspection
The officer asks for March. You produce the daily register in the browser — every entry carrying its terminal, timestamp and verification method. The conversation is about facts, not about the software.
06
A machine dies on Tuesday
The dealer swaps the unit; you register the replacement and push the employee list. Compatible iClock enrolment data may be reusable on a compatible replacement; other formats, including Realtime biometrics, can require device-side re-enrolment. Confirm this before selecting the replacement.

Reliability
Built so a punch is never lost
"Reliable" is an adjective every vendor uses, so here it is as mechanisms instead — what actually happens when the internet drops, a machine dies or somebody disputes a late mark.
Internet down, gate still works
Verification happens on the terminal itself. During a network interruption, a supported device can keep matching locally and buffer punches for upload when connectivity returns. A power cut still requires backup power for the terminal and network equipment.
A dead machine has a documented recovery path
Employee profiles and supported enrolment payloads are held centrally. Compatible iClock templates can be restored to compatible iClock devices; other replacements can require biometric re-enrolment. The model-specific recovery plan is confirmed before rollout.
No office PC to lose
The classic failure of Indian attendance systems is the accountant's desktop dying with the history and enrolments on it. Here there is no desktop software and no local database — nothing at your site holds the only copy of anything.
Every punch is defensible
Each record keeps its timestamp, its terminal and the method that verified it — face, finger, card or PIN. Nothing is silently rounded or corrected, which is what settles a disputed late mark.
A decade in production
The engine underneath has processed attendance continuously for over ten years across 1,000+ locations — through festival-season load, monsoon outages and every firmware quirk the Indian market ships.
Data stays in India
Attendance and templates are stored on infrastructure in India, run by the company that writes the software — not resold through a chain of white labels.
Scale figures are for AIONDATA's attendance platform — the same engine, database and device protocols that power AionHRMS — accumulated across AIONDATA products including AdviceFit since the platform first went live.
Security
Biometric data, handled like it matters
Employees hear "fingerprint database" and imagine the worst. Here is the actual design — precise enough to show the staff who ask.
Device-specific biometric data
Fingerprint devices use mathematical templates. Some supported face-terminal workflows also use a face or profile photo for enrolment and cross-device sync. Neither is included in ordinary attendance exports or the partner API.
Data stays in India
By default attendance and templates live on infrastructure in India (Europe for EU/UK customers where compliance requires it), run by the company that writes the software.
Scoped, hashed, logged
Role-based access for people; API keys scoped read/write, stored only as SHA-256 hashes, rate-limited and fully logged.
No Aadhaar, no data resale
No Aadhaar data is ever touched, and your register is processed to run your service — never sold, shared or mined.
Open by design
An API your ERP, CRM and AI agents can build on
The console you see is a client of the same backend you can integrate with. Scoped, rate-limited keys pull attendance into the systems where it is used — and push actions back: block a leaver from your HR system, enrol from your onboarding flow, feed the month straight into your payroll journal.
Partner API — live
People, attendance and payments scopes; keys hashed, quota'd and fully logged.
ERP, CRM & BI sync
Pull by date range on your schedule; write back the actions your systems own.
MCP for AI agents — in development
Agents will query attendance and act within scoped permissions. Early access is open.

What AionHRMS does not do
Stated here rather than discovered three weeks into a rollout.
- Statutory returns (PF ECR, ESI, TDS returns) — PF and TDS deductions can be computed on the payslip, but nothing is filed, and ESI and professional tax are not computed
- Leave encashment and the statutory leave-with-wages register — leave requests and approvals, quotas, holidays, weekly offs, short leave and comp-off are built; these two are not
- Offline phone attendance and background location tracking — not part of the mobile punching workflow
- Student attendance for schools — staff attendance and access only
- MCP server and outbound webhooks — in development; API access today is provisioned per organisation, not self-serve
Frequently asked questions
- Do you supply the biometric machine as well, or only the software?
- Both, end to end. AionHRMS is sold through authorised biometric hardware dealers across India, so one quote covers the machine (fingerprint, face or RFID terminal), installation and cabling, the cloud attendance software, and payroll behind it. If you already own an eSSL, ZKTeco or Realtime terminal, the hardware line usually disappears entirely — the existing machine is repointed at our server from its own settings menu.
- Does AionHRMS do payroll, or only attendance?
- Both. Attendance from your biometric terminals feeds a shift-based payroll engine: each employee has their own duty times, punches are bucketed to the right 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 tracked and settled against future payments. What it does not do is statutory filing — PF, ESI and TDS returns are still filed by you or your CA.
- Will it work with the biometric machine I already own?
- In most cases yes. AionHRMS implements two push protocols that between them cover the mainstream Indian market: iClock/ADMS — used by eSSL, ZKTeco and other terminals speaking standard ADMS — and Realtime's own native protocol. The terminal is repointed at our server from its own settings menu, so no new hardware is needed. Send us the model and serial and we will confirm before you commit.
- Is this an online biometric attendance system?
- Yes — fully online. The terminal pushes every punch to the cloud, and attendance is read from any browser or phone, from anywhere. There is no desktop software, no local database and no dependence on one office PC. When the internet at your site goes down, the terminal keeps verifying people locally and buffers punches in its own memory, then uploads the backlog when the connection returns — so being online never means losing attendance to an outage.
- How reliable is it, really?
- The attendance engine behind AionHRMS is AIONDATA's platform, which has processed biometric attendance across AIONDATA products for over ten years and more than a thousand locations. Verification happens on the terminal and supported devices buffer punches during connectivity cuts. Replacement and enrolment recovery are model-specific: employee profiles are pushed centrally, compatible iClock templates can be reused on compatible iClock terminals, and Realtime devices require biometric enrolment at the terminal.
- What is the best biometric attendance system for an office?
- One that survives year two. Confirm the exact device models and enrolment-reuse workflow, then evaluate multi-brand reporting, server-side late and overtime rules, access revocation and payroll. AionHRMS combines confirmed eSSL, ZKTeco and Realtime models in one attendance register, while documenting where biometric enrolment must still happen at a terminal.
- What makes this different from the free software with my device?
- Bundled software is generally designed around its manufacturer's ecosystem. AionHRMS supports confirmed eSSL, ZKTeco and Realtime models in one register and carries attendance through to shifts, late rules and salary. If you run mixed hardware, ask every vendor to name the exact models and third-party brands it supports rather than assuming from the logo.
- Do employees have to enrol on every machine?
- It depends on the terminal model and protocol. Employee profiles can be pushed centrally. Compatible iClock terminals can reuse supported biometric templates, while Realtime terminals require biometric enrolment at the terminal. Confirm the exact models and enrolment workflow with us before planning a multi-site rollout.
- Can it handle multiple branches?
- Yes. Confirmed terminals at every location report into one organisation. Head office sees a combined register and a branch administrator sees only their own site. Employee profiles can be pushed centrally; biometric enrolment reuse depends on the device family and may require enrolment at each Realtime terminal.
- Do you cover Delhi NCR?
- Yes — Delhi NCR is home ground. AIONDATA's engineering office is in Noida, and AionHRMS is supplied and installed through biometric dealers across Delhi, Noida, Gurugram, Faridabad and Ghaziabad. Offices split across NCR's state borders — a Delhi office, a Noida back office, a Bhiwadi plant — run as one account with one register.
- What does a biometric attendance system cost?
- Three parts: the terminal (one-time, and often ₹0 if your existing machine is supported), installation (one-time, by the local dealer), and software (recurring). AionHRMS software is a flat annual subscription by headcount band with unlimited terminals and sites — no per-employee-per-month meter — and it is invoiced only after your devices are live. See the pricing page for the bands, or contact us for a written quote covering all three parts.
- Can attendance data flow into our CRM, ERP or payroll software?
- Yes — through the partner API, which is live in production. Scoped, rate-limited keys let your systems pull attendance by person or organisation-wide over date ranges, create people, record payments, and block or unblock device access; every request is logged, and keys are stored only as hashes. An MCP server, so AI agents can work with the same data under the same permissions, is in development. API access is provisioned per organisation — tell us what you are integrating.
