The sensor that carries most of the volume. A semiconductor sensor reads the ridge pattern rather than an image of it — the difference between a dry winter finger and a failure.
What it changes in practice
- 360° read angle
- 250 credentials per lock
- FAR ≤0.0001 %, FRR ≤0.1 %
- Anti-static, scratch-resistant coating
Honest limit: the silicon may be rated wider than the assembled lock. The cell and the display set the real range, which is why the face platforms are published at −20 °C to +40 °C.
