| Metric | Observation | |--------|-------------| | | ~0.8 s per finger on a typical F18 sensor (including image acquisition and template creation). | | Verification latency | ~0.35 s for a 1‑to‑1 match; 1‑to‑N (up to 10 k templates) stays under 0.9 s on a mid‑range laptop (i5‑8250U). | | CPU usage | Light – <5 % of a modern core during continuous capture. | | Stability | The SDK is battle‑tested in many commercial access‑control products. Crashes are rare; most issues stem from improper COM registration or conflicting drivers. | | Thread safety | The core DLL is not thread‑safe; you must serialize calls or use a dedicated worker thread per device. |
