Construction Site Clock-In | GPS Geofenced Time Tracking
Construction site clock-in with GPS geofencing & QR kiosk. Track crews across sites, stop buddy punching, offline mode & SEPA payroll. Free trial.
Construction crews move sites daily and often have no signal. Chegatta clocks them at the gate, offline if needed.
The Construction Problem
Daily hires, hard hats, no phones on scaffolding. Paper timesheets = 4.2% payroll leakage. A gate kiosk + phone GPS fixes it.
Gate kiosk, no phone needed
Shared tablet, QR badge scan, camera preview. Works offline, 30s idle reset.
Geofence per build
100-500m radius per site, bound to site — no cross-site clocking. GPS + SHA-256 fingerprint.
Offline then sync
Punch queued locally, syncs when back. Supervisor approves overtime per site.

Why Construction Needs Its Own Setup
High turnover
Daily hires: issue QR badge in seconds, no app download or passwords.
No signal in basement
Basement, tunnel or remote site: punches queue offline and upload when back, no duplicates.
Audit-proof for ACT
Every punch stores time, location, device fingerprint & optional photo — 5-year trail per labour code.
The same QR kiosk used in restaurants and warehouses: 1 tablet = 1 site, photo-optional & anomaly panel. See Kiosk Time Clock.
Construction FAQ
What if there's no signal on site?
Kiosk queues punches locally and syncs when back. Idle 10–3600s (default 30s) returns screen to ready.
Can the same badge be used on multiple sites?
Yes, but each kiosk is bound to one site. Punch is always logged to correct site — no cross-clocking.
