Key points
- A geofence is a virtual boundary around a site. A check-in only counts when the phone is inside it.
- Done well, it replaces paper sign-in sheets and clocking hardware with the phone workers already carry.
- The value comes from what happens next: attendance should become the timesheet, without re-keying.
What a geofence is
A geofence is a virtual boundary drawn around a location, usually as a radius from a point on a map. When a worker checks in using an app, the phone’s location is compared with the boundary. Inside, the check-in counts; outside, it does not.
Compared with paper and hardware
Each approach has trade-offs:
- Paper sign-in sheets are cheap but easy to fill in for someone else, hard to read and slow to process.
- Clocking hardware is reliable at one entrance but costly to install and move between sites.
- Phone-based geofencing works on any site from day one, with no hardware, and records where and when each check-in happened.
What makes a good system
Look for a system that handles the edge cases, not just the happy path:
- A geofence radius you can set per site.
- Site hours, so forgotten check-outs are closed automatically.
- Break and lunch rules, paid or unpaid, by company or site.
- Offline check-in that syncs when signal returns.
- Corrections by a supervisor, with the original and the change both recorded.
- A clear privacy position: location used at check-in and check-out, not tracked all day.
From attendance to pay
Attendance on its own is a report. Its value comes when it becomes the timesheet, is approved by the client, and drives both payroll and invoicing with the same hours. Every manual step between them is a place where hours can be lost or added.
Introducing it to a workforce
Explain why it is being introduced, what location data is collected and when, and how it protects workers too: accurate records mean accurate pay. Keep the app simple, and make sure there is a fallback for anyone without a smartphone.
Questions
Does geofencing track workers all day?
It does not have to. A well-designed system checks location at check-in and check-out to confirm the worker is on site.
What if there is no signal on site?
A good app stores the check-in on the phone and sends it when the signal returns.
