Geofenced Site Attendance
On a construction site, "I was here" is the most expensive sentence in labour. Paper attendance cannot prove it, and a foreman's memory certainly cannot. Geofenced site attendance turns presence into evidence: a worker can only check in from inside a 50-metre radius of the site gate, on their own phone, at a timestamped moment that nobody can backdate.

What geofenced attendance means
A geofence is a virtual boundary drawn around a real place. FundiPay draws a 50-metre radius around each site — usually centred on the gate — and only accepts a check-in from inside it. A worker standing at the site in Ruiru cannot mark themselves present on a project in Athi River, and a foreman cannot quietly add a name from the office.
- A 50-metre radius around the site gate or project location.
- Check-in by OTP on any phone — no app to install.
- A rejected check-in when the worker is outside the fence.
- A timestamp and GPS coordinate recorded for every entry.
Check-in on any phone
Workers do not need a smartphone. They enter their number, receive a one-time password by SMS, and check in — the whole thing takes seconds. A basic handset is enough, which matters on sites where half the crew carries a feature phone and shares an umbrella on a hot morning.
For crews that arrive together, the foreman can run a gang check-in against the fence, so twenty workers do not have to queue at the gate while a mixer is running. The record still captures the geofence and the time.
Why the timestamp cannot be faked
Each check-in carries the phone number, the GPS coordinates and a server-side timestamp. A worker cannot send a friend to check in for them, because the OTP goes to the worker's own number and the location comes from their own handset. Once the day is locked, the record is frozen. Corrections pass through a visible adjustment trail, so any change is attributed and explained rather than silently erased.
From attendance to proof
Geofenced attendance is the evidence layer under the whole payroll. It feeds the muster roll, it settles disputes about who worked which day, and it gives a developer or NCA inspector a defensible answer when they ask who was on site on a given date. You are not paying on trust; you are paying on records.
Frequently asked questions
What if GPS is poor in a basement or on a large site?
The 50-metre fence is set generously enough to cover a working site, and the radius can be widened for large or split sites. Where signal is genuinely weak, the foreman can confirm the gang check-in before the day is locked.
Can a worker check in from home before travelling?
No. A check-in outside the geofence is rejected. The worker must be within the site radius when they check in, so a check-in proves arrival, not intention.
Does geofenced attendance work on feature phones?
Yes. Check-in is by OTP over SMS, so the worker needs only a phone that can receive a text. Smartphones allow extra features like viewing payslips, but they are not required.
Who can see the attendance data?
Foremen see and review their own site's attendance; contractors see every site they run; developers and auditors can be given read-only visibility. Access follows roles, so nobody sees sites they are not accountable for.
