A Guide to Choosing the Right Biometric Hardware for Your Facility

Match the Device to the Environment

Selecting biometric hardware comes down to four factors: facility size, throughput at peak times, environmental conditions, and budget. A dusty factory floor, a humid coastal plant and an air-conditioned head office each place different demands on a sensor.

Specifications That Matter

When comparing devices, hold vendors to these minimums:

• False Acceptance Rate (FAR): below 0.001%
• False Rejection Rate (FRR): below 0.1%
• Throughput: at least 30 verifications per minute at a busy entrance
• Template capacity: at least 10,000, with headroom for growth

How to Choose a Vendor

For high-traffic entrances, multi-modal devices that combine fingerprint and facial recognition give the best balance of speed and reliability. For clean-room environments such as hospitals and laboratories, contactless iris readers are the better fit. Always request an on-site demo with your actual workforce — laboratory numbers rarely survive contact with a real shift change.
