Geofencing

Geofencing is the use of a virtual boundary around a real-world location. In time and attendance, a clock-in is only accepted, or is flagged, based on whether the device is inside that boundary.

Geofencing — definition

Geofencing draws a virtual boundary around a real-world location — a site, a depot, a venue. In time and attendance, it uses the device’s GPS position to confirm whether a clock-in happened inside that boundary, so you can tell on-site hours from off-site ones.

Why it matters

Why geofencing matters

A clock-in tells you when someone started — geofencing tells you where. For a multi-site or mobile workforce, that difference is the whole point: it is how you separate hours genuinely worked on site from clock-ins made on the bus, at home, or at the wrong location entirely.

It also gives you a live register of who is physically present, which matters well beyond payroll. On a construction site or in a warehouse, being able to say exactly who is on site right now — for a fire roll-call or a visit from an inspector — is a safety and compliance requirement, not a nicety.

Geofencing is only as trustworthy as the location data behind it. GPS accuracy varies indoors and in dense areas, so a sensible system records the reported accuracy, sets a proportionate radius, and treats a borderline reading as something to review rather than silently accept. It works best alongside a verified identity at clock-in, so you know both who clocked in and where.

In practice

A geofence is a centre point plus a radius — typically tens to a few hundred metres.
Each clock event records its distance from the centre, so off-site is obvious.
GPS accuracy varies; a good system logs accuracy and reviews borderline reads.
Paired with identity, it answers both who and where.
How TempClock relates

How TempClock relates

Geofencing is built into every TempClock clock event. You set a centre and radius per site; when a worker clocks in, their distance from the centre is recorded alongside the face-match score, and an off-site clock-in is flagged so a manager sees it straight away.

  • Set a geofence per site with a radius that suits the location.
  • Distance from the site centre is recorded on every clock-in and travels to the timesheet.
  • Off-site clock-ins raise an alert, and the live board shows exactly who is on site now.

Each clock-in records its distance from the site centre, so an off-site attempt is flagged the moment it happens — not discovered on the timesheet.

Every clock event carries its distance from the site, on site or off.
