Construction crews move between sites with no fixed office and patchy signal — biometric attendance on mobile devices gives accurate, geofenced hours even offline.
Why sites are hard
Transient crews, subcontractors and high turnover make paper sign-in sheets unreliable and hard to bill from.
How biometric attendance helps
Workers clock in by face on a site tablet inside a geofence, offline if needed, and gates open only for verified workers — with accurate hours per site and subcontractor.
Recommended setup
Phones or tablets for crews, a rugged terminal or IP camera at the gate, and access control on barriers.
FAQ
Does it work without internet on site? Yes — attendance is recorded offline and syncs automatically when a connection returns.
