Access control vs biometrics: which is right for your project?
Cards and mobile credentials win on speed, scale and visitor flow. Biometrics (face, fingerprint, iris) win on identity assurance for sensitive zones. Most real projects use both — cards for daily flow, biometrics for restricted doors — under one policy engine with full audit logging.
How to picture it.
Decision tree mapping door type → credential type → reader type → backend integration, with OSDP vs Wiegand and on-device vs server-side matching highlighted.
From the field.
An R&D facility deployed face recognition at lab doors and mobile credentials at general office floors, both governed by one policy engine — saving operations cost without weakening sensitive-zone identity assurance.
What to take away.
- 1Match credential strength to the zone's risk profile.
- 2Specify OSDP, not Wiegand, for any new install.
- 3Keep enrolment and revocation workflows simple — they break in practice.
- 4Audit logging is the deliverable, not a feature.

Is face recognition reliable?+
Modern face systems work well in controlled lighting with quality optics. They struggle outdoors or with poor enrolment hygiene.
Can we mix brands?+
Yes — under an open access-control platform. Avoid being locked into one OEM's reader-and-controller stack.
