A Sign-In Sheet Can't Stop a Ghost. A Selfie With GPS Can.

Ghost employees — names on the roster who were never on site — inflate labor billings, poison certified payroll, and turn safety records into fiction. Arkvos makes every attendance record self-verifying: a photo of the person, coordinates inside the geo-fence, and a cryptographic seal applied at capture.

One Worker, One Verified Record

Each check-in requires a live selfie from the worker's own phone inside the site geo-fence. One foreman with a stack of names can't manufacture attendance.

Billing You Can Certify

When labor hours are invoiced against attendance, verified check-ins mean the hours you bill — or the hours a sub bills you — trace to people who were physically present.

Tamper-Evident by Design

Records are hashed with record-integrity at capture. Any alteration after the fact breaks the hash — which is exactly what an auditor, GC, or prosecutor checks.

Honest Exceptions

Manual check-ins recorded by a supervisor are allowed but labeled as such in the audit trail, so verified and unverified attendance are never blended silently.

Frequently asked questions

How does Arkvos actually prevent ghost employees?

By binding attendance to physical evidence: the worker's selfie, GPS coordinates inside the site geo-fence, and a device timestamp — all sealed with a record-integrity hash the moment of capture. A record for someone who wasn't there would need a photo of them, at the site, at that time.

Can't someone check in and leave?

Arkvos verifies briefing attendance — presence at a specific moment — which is the record that matters for safety compliance and for proving the roster was real that morning. It's evidence of presence, not surveillance of movement.

Does this work for subcontractor crews?

Yes. Subs check in with the same QR scan and no accounts, so a GC can require verified attendance across every trade and compare it against invoiced labor.

Is the selfie data secure?

Photos and coordinates are stored in your organization's records, access-controlled by role, and used for verification — the audit PDF shows exactly what was captured and when.

Already holding an OSHA citation?

Arkvos offers a free OSHA citation response generator. Upload the citation and get a formal response letter, a corrective action plan with dates, and a checklist of evidence to attach. Employers have 15 working days from receipt of a citation to contest it. Open the free citation responder.

Factual anchors and primary sources

Arkvos separates product capabilities from regulatory requirements. For federal OSHA requirements, the primary authority is OSHA's current regulations and guidance. California construction employers should also review the applicable Cal/OSHA Title 8 requirements.

OSHA 29 CFR 1904.33 requires the OSHA 300 Log, annual summary, OSHA 301 Incident Report forms, and privacy case list if one exists to be retained for five years after the end of the calendar year they cover. Cal/OSHA Title 8 §1509(e) requires construction supervisors to conduct toolbox or tailgate safety meetings, or equivalent, with crews at least every 10 working days. Requirements vary by jurisdiction and work activity, so employers should verify the rule that applies to their facts.
