Contract Worker Attendance Zambia — Face Clock-In Timesheets Clients Can Check

Where the wage bill leaks

Two parties, one disputed timesheet.

The client says the crew left early. The supervisor says they didn't. Without evidence, the invoice gets cut.

Disputed invoices

A timesheet from the device, with times from the server and the coordinates, settles the argument.

Padded placements

A worker billed to the client and paid on payday who was not on site. No face clock-in, no paid day.

Many clients, many sites

Every clock event records where it happened, so each site's hours are separate on the map.

A worker clocking in with their face on an Android device at the site gate

One device at the gate. The whole site clocked.

Enrol each worker once on the Android phone or tablet at the site. From then on they look at it, blink, and are clocked in — and do the same to clock out. Matching runs on the device, so a morning muster of hundreds moves at the pace of a glance, with or without signal.

Blink liveness check — a printed photo or a picture on a screen does not pass
The time comes from the server's clock, not the phone's
GPS coordinates and their accuracy on every clock-in and clock-out
Saved on the device first and sent when signal returns, never twice

A monthly timesheet PDF with a verification code

A timesheet the client can check.

Export each worker's monthly timesheet as a PDF carrying a verification code, or as Excel: days present, absent, late and short, and the minutes late. Overrides are marked, each with a reason and a site photo.

Xeel pay runs paid from the days and hours workers clocked with their face

Payday reads the clock.

Choose how each worker is paid. On a daily rate, the pay run pays the days their face clocked in. On an hourly rate, it pays the hours between their face in and their face out. PAYE, NAPSA and NHIMA are worked out on what was actually earned, and each payslip goes to the worker on WhatsApp.

Daily rate: days clocked × the rate — no clock-in, no pay for that day
Hourly rate: hours clocked × the rate
A day with a clock-in but no clock-out pays no hours, and is named before you release the run
Monthly salary: paid as normal, with present, absent, late and short days on the timesheet

Questions

Contract workers, answered.

How can a labour contractor prove contract workers' hours to a client?

Clock the workers in and out with their face at the client's site. Each record carries the time from the server, the GPS coordinates and the face match, and overrides need a reason and a photo. Export the monthly timesheet per worker as a PDF with a verification code, or as Excel, and send it with the invoice.

Can the same system pay the contract workers?

Yes. Workers on a Daily rate are paid for the days they clocked and workers on an Hourly rate for the hours. Xeel works out PAYE, NAPSA and NHIMA on each pay run and sends payslips on WhatsApp.

We have workers at several client sites. How is that handled?

Put an Android phone or tablet at each site and enrol that site's workers on it. Every clock-in records its coordinates, and the attendance map shows where each day was worked. A clock-in outside a site boundary is recorded with its coordinates, not refused.

Does it work without internet or network?

Yes. Faces are matched on the phone or tablet itself and every clock-in and clock-out is saved on the device first, then sent when signal returns, each with a key so nothing is recorded twice. The time is taken from the server's clock, so changing the time on the handset does not change the record.

What does it cost, and is there a fee per worker?

Face clock-in is part of Xeel, priced per month as one app. There is no charge per worker or per face, and the employee register is free with every plan. Message O'Sense on WhatsApp on +260 974 546 632 for current pricing.

Where is the face data kept?

The face template -- the numbers a face is turned into -- is stored encrypted on the device, with the key in the Android Keystore, and is never uploaded. Only the enrolment photo reaches the office, so a replacement phone can be set up again. How O'Sense handles biometric data under Zambia's Data Protection Act 2021 is in the privacy policy.

Known limits — not bugs. Face clock-in runs on Android phones and tablets, not iPhone. A clock-in outside a site boundary is recorded with its coordinates, not refused. Monthly-salaried staff are paid their salary, with attendance shown rather than deducted. Xeel records attendance; it does not open doors or turnstiles. The blink check stops a photo or a screen; it is not a claim that no attack can ever work.

Bill the client for hours you can prove.
