Access Control vs Biometrics: Choosing the Right Entry System
RFID cards, PIN pads, fingerprint, face recognition — a practical comparison for offices, factories and healthcare campuses.

Not every door needs the same level of protection. We help clients pick the right mix of credentials — from PIN pads at breakrooms to multi-factor biometrics on server rooms.
Quick comparison
| Method | Best for | Watch-outs |
|---|---|---|
| RFID / Prox card | General staff doors | Cards get shared/lost |
| Fingerprint | Mid-security zones, time attendance | Dirty/wet fingers reduce accuracy |
| Face recognition | Touchless, high-traffic lobbies | Needs good lighting |
| Palm-vein | Data centers, labs | Higher device cost |
Our recommendation for most SMBs
Layer them: RFID for perimeter, biometric on critical rooms, and a cloud-hosted controller so HR sees attendance and security sees exceptions in the same dashboard.
