Devices and integration
Biometric Hardware
End-to-end integration of fingerprint readers, face terminals, and card systems — with offline resilience and centralized fleet management.

overview
We integrate leading fingerprint scanners, facial recognition terminals, and proximity card readers onto a unified software layer with encrypted template sync.
Edge-first matching keeps doors operating through network outages; events buffer locally and reconcile to the central system when connectivity returns.
Devices buffer access events locally during outages and sync chronologically when connectivity returns — attendance records remain complete regardless.
what we build
01
Fingerprint, face terminal, and proximity card readers on a unified interface
02
Remote firmware management and device health monitoring across sites
03
Encrypted template storage and secure edge-to-central sync
04
Edge-first matching for sub-second latency and offline resilience
05
Offline event buffering with deterministic chronological reconciliation
how it works
From input to outcome.
- 01
Enroll
Templates encrypted and distributed to relevant devices on enrollment.
- 02
Match at edge
Device compares biometric locally; no server round-trip required.
- 03
Buffer offline
Access events queued locally with timestamp and decision during outages.
- 04
Sync
Buffered events committed chronologically when connectivity restored.
use cases
Common applications.
01
Biometric door access
Sub-second entry, offline-resilient, full audit trail per access event.
02
Time and attendance at the device layer
Readers at site entrances feed verified check-in events to attendance system.
03
Multi-factor access for sensitive areas
Face + fingerprint + card combinations configurable per zone.
04
Multi-site reader fleet management
Firmware, templates, and access rights managed centrally without site visits.
05
Retrofit integration with existing infrastructure
Biometric layer over existing Wiegand or OSDP wiring; no infrastructure replacement.
