Geofenced Attendance: Proof of Presence for Field Teams
For construction, security and cleaning contractors, proving someone was on site matters as much as counting their hours. Here is how geofencing does it.
By OPPERIQ Product · Product Team
A timesheet says an employee worked eight hours. It does not say where. For a contractor billing a client for guarding a site or cleaning a building, that difference is the entire invoice — and it is the thing most often disputed after the fact.
Validating the check-in, not auditing it later
OPPERIQ lets administrators define circular or polygon geofences and assign them to employees. When someone checks in, their coordinates are validated against the zones assigned to them, and a check-in from outside those zones is rejected at the point of capture rather than flagged during a monthly review.
- Circular and polygon zones per site, assignable per employee.
- Optional face verification on check-in and check-out, compared against a registered face profile.
- Correction requests when a legitimate check-in fails, routed to a manager, HR or a reviewer for approval.
- Break tracking, shift start and end, and an SOS alert for field emergencies.
What geofencing does not solve
Coordinates are reported by the employee's device, so geofencing raises the effort required to misreport a location without making it impossible. That is why the correction workflow, the approval chain and the audit trail exist alongside it: the value is a defensible record with a named approver on every exception, not an unfalsifiable one.
The downstream benefit is reconciliation. Validated hours feed approvals, and approved hours feed payroll runs with overtime and deduction rules already applied, so the same record that settles a client dispute is the record that pays the employee.
