What is NFC time tracking?
An NFC site tag (or QR code) is placed on site. The worker holds their phone to the tag — a web page opens and the time is recorded. No app, no app-store login, works on Android and iPhone.
Tamper-proof against tag cloning
- GPS location on every clock-in — with a per-site geofence.
- Anti-clone heuristic blocks impossible clock-ins (same worker in two places at once).
- Blocked/suspicious clock-ins visible in the dashboard and exportable as CSV.
- 6-digit worker PIN against misuse.
Why app-free?
Construction workers often switch devices and languages. Pure web capture via NFC/QR removes the barrier to entry — no updates, no install, multilingual UI.
Customs- & GoBD-compliant
Every record is audit-proof with time-stamp and location. The working-time proof incl. location/map link exports for customs (FKS) inspections.
FAQ
Do workers need an app?
No. Tapping the NFC tag or scanning the QR opens a web page. No app install — Android & iPhone.
How does EmployGuard prevent tag cloning?
Via GPS geofence and an anti-clone heuristic: clock-ins from impossible locations (unrealistic speed between two points) are blocked and logged.
What does an NFC tag cost?
Physical EmployGuard NFC site tags start at €2 per tag. One tag covers all authorized workers on that site.
Can I use only QR codes?
Yes. You can print QR codes yourself (posters/labels) or order physical NFC tags — or combine both.
