Biometric time tracking is a way of proving that the person who started the shift is the one on the schedule. A terminal recognises a face or a fingerprint and records the time; unlike a card or a badge, biometrics cannot be handed to a colleague, so clocking in for a friend stops working.
The problem it solves
Paper logs and cards satisfy the requirement to keep records only on paper. The log is filled in from memory at the end of the shift, the card is passed to a workmate, and the gap between hours claimed and hours worked surfaces at payroll — too late to fix.
Biometrics removes the substitution itself and settles arguments about time: every record has an exact second and a photograph of the event. That matters most where the shift does not start in an office — on the shop floor, at a store, on site.
What to plan for
The technology is straightforward; failed rollouts usually break not on recognition but on logistics.
- Throughput: one device and a hundred people arriving by 8:00 is a queue, not a record. There must be enough terminals for the shift peak.
- Working conditions: dust, gloves and cold defeat fingerprints, which is why manufacturing sites normally choose face recognition.
- Processing biometric data requires employee consent and an internal policy — part of the rollout, not a formality after it.
- Offline mode: a terminal has to keep recording when the network drops and send the records on once it is back.
How this works in Verifix
Verifix integrates with FaceID terminals and access-control hardware (HikVision, Dahua, ZKTeco) and takes from them not an event log but finished records, already matched against the employee's shift schedule.
From there a record travels on its own: into the timesheet, into hours worked and overtime, and from those into the payslip. A mobile app with geofencing covers the people who never pass a terminal — couriers, installers, sales reps.
In short
The value of biometrics is not recognition accuracy but the fact that a record cannot be handed to someone else — that is what makes a timesheet trustworthy.
