How face recognition attendance actually works
During enrolment the terminal computes a template — a set of numerical features derived from the face — and stores that. On every subsequent scan it computes the same features and compares. The original image is not retained, which is both a privacy property and the reason the process is fast enough for a queue at 09:00.
- Enrolment captures a template, which AionHRMS also stores centrally
- Matching runs on the device, typically in well under a second
- The template propagates to your other terminals so nobody re-enrols
- Every punch records that it was verified by face rather than finger or card
