Why is face recognition attendance better than fingerprint biometrics on construction sites?

Fingerprint biometrics frequently fail on construction sites because workers have dust, cement, or worn fingerprints from manual labour, and the expensive scanners break down outdoors. Hajari Lens uses AI facial recognition on standard smartphone cameras, making check-ins instant, hygienic, contactless, and 100% reliable in dusty environments.

Do I need to buy expensive facial recognition hardware?

No. Hajari Lens turns any standard Android phone, iPhone, or budget tablet into a powerful biometric face scanner without requiring any external hardware or installation fees.

Does Hajari Lens prevent photo spoofing or screen replay attacks?

Yes. Hajari Lens incorporates AI liveness detection and anti-spoofing algorithms to ensure that printed photos, mobile screen replays, or non-live faces cannot mark attendance.

How quickly can workers mark attendance during morning rush hours?

Worker identification takes less than 1 second per person. Supervisors can also use rapid kiosk or walk-by scanning mode to mark hundreds of workers in just a few minutes.
