A facial recognition attendance system that proves who turned up
Workers clock in with their face on any tablet. Each clock-in is matched against the enrolled worker, checked for liveness, and logged with its confidence score — in under two seconds, with no photo stored.
0%
Typical face-match confidence at clock-in — logged against every hour, so the hours you bill are the hours you can prove in under 2s.
Biometric science, not photo comparison
AdaVision ID v3 is our own face-recognition engine — a deep convolutional neural network that turns each face into a 1024-dimensional vector signature and matches it server-side against your whole enrolled workforce. Nothing about it depends on storing a photo.
-
Enrol once
A worker enrols from a short capture. The system computes a 1024-dimensional vector signature and discards the imagery — the signature cannot be turned back into a face.
-
Match at the kiosk
At clock-in, a fresh signature is compared by cosine similarity against the whole workforce in a single 1:N call — robust to beards, glasses, hairstyles and different cameras.
-
Confirm liveness
ISO/IEC 30107-3 active liveness confirms a real person is present, not a photo, a screen or a mask, before the clock-in is accepted.
-
Log the proof
The match score, the runner-up gap and the liveness result are written to the timesheet alongside the GPS reading — the hour carries its own evidence.

A photo of a face will not clock anyone in
Buddy-punching only works if the system can be fooled. Active liveness, tested to ISO/IEC 30107-3, confirms a live person is present before any clock-in is accepted.
Held-up photos
A printed or on-screen photo is flat and lifeless. Liveness reads depth and micro-movement, so a picture of a colleague is rejected.
Replayed video
A recording played back on a phone fails the same checks — there is no live response to the prompts, so the attempt does not pass.
Masks and prints
Presentation-attack detection is tested against the recognised ISO/IEC 30107-3 standard, covering 2D and 3D mask attacks alongside photo and video.
When a match is not confident enough, nobody is locked out
If a face cannot be matched with enough confidence — poor light, a new injury, a bad camera angle — the worker clocks in by PIN and the event is flagged for a manager to review. Work is never blocked; the exception is simply recorded.
Biometric clocking is legal in the UK — done correctly
Facial data is special category data under UK GDPR, so it needs a lawful basis, a clear privacy notice and proportionate safeguards. TempClock is built so you can deploy it that way, not work around it after the fact.
No photos stored
Faces are held as irreversible vector signatures, not images — the underlying biometric cannot be reconstructed.
A workable alternative
Every worker can clock in by PIN, so facial recognition is never the only route to recording an hour.
UK-hosted, append-only
Data is held on UK infrastructure and sensitive actions are written to an append-only audit log.
One-click SAR export
Produce every record held on a worker for a subject-access request, packaged in a single export.
This is general guidance on how the system is built, not legal advice. Your data protection responsibilities as an employer remain your own.
Hours you can prove, the same day
Face-verified clock-ins close the gap between the hours worked, the hours billed and the hours you can evidence — without slowing anyone down at the kiosk.
Buddy-punching, designed out
A worker cannot clock in for someone else, because the face has to match the enrolled worker and pass liveness. The score travels with the hour.
Disputes you can settle
When a client queries an hour, you answer with a verified time, a location and a match score — not one person's word against another's.
No hardware to buy
The kiosk runs in a browser on any tablet or phone with a camera. There is nothing to install and no proprietary clocking terminal to source.
Live, byte-for-byte proof
The match score, runner-up gap and liveness result are written to the timesheet as the day happens — nothing is reconstructed afterwards.
A verified face is the start of the record
The clock-in carries on through geofencing, the kiosk and a payroll-ready timesheet. See how the rest of the system fits together.
