Biometric check-in
Face ID or fingerprint confirms the person checking in — stronger than a handwritten name on a sheet.

Verification
Site records you can stand behind on busy construction sites
When attendance, compliance, and emergency readiness matter, paper sign-in sheets fall short. HammerTime combines biometric check-in, event-based GPS, digital signatures, offline sync, a tamper-evident audit trail, certificate visibility, and frozen roll call snapshots — so your records are clearer, harder to dispute, and easier to review later.
What gets verified
Verification is woven through check-in, compliance, timekeeping, and emergency workflows — not bolted on as an afterthought. Together these signals help you demonstrate compliance; they do not guarantee it on their own.
- Biometric check-in — Face ID or fingerprint confirms identity at site check-in on supported devices.
- GPS at punch — location is captured at clock and compliance moments when policy requires it, not as continuous surveillance.
- Digital signatures — arrival forms, toolbox talks, safety plan acknowledgements, and employment documents stay linked to the person and the record.
- Offline-first — clock events, journal entries, and uploads queue when signal drops, then sync with duplicate-safe receipts on reconnect.
- Tamper-evident audit trail — a chronological record of who did what, when, and from where — for supervisors and auditors.
- Certificate visibility — licences, training, and expiring credentials surfaced before problems hit the gate or an audit.
- Frozen roll call snapshot — emergency roll call captures a point-in-time roster so managers work from a fixed headcount, not a moving live feed.
GPS at punch
Location captured when workers clock or complete compliance actions — policy-based, event-driven context.
Digital signatures
Sign-offs on forms and documents stay connected to the wider site and compliance record.
Audit trail
Every key action logged with timestamps and context — a defensible history when questions arise later.
Auto check-in is different from biometric check-in
When geofence-based auto check-in is enabled, it is not driven by biometrics. The worker always receives a prompt and must confirm every time before a clock event is recorded. Biometrics are used for site check-in identity confirmation — not as a silent background trigger for automatic time entries.
Verification supports better decisions — not automatic compliance
Stronger records give site managers a clearer base for attendance, subcontractor oversight, payroll-ready time exports, and emergency response. HammerTime helps you demonstrate compliance with a defensible audit trail; your policies, supervision, and follow-through still matter.
