Biometric device
A facial-recognition access-control integration. Device-sourced entries are auto-approved on ingestion, the device is treated as a trusted witness, so a machine-read clock event needs no human review. A duplicate scan within 120 seconds is flagged harmless rather than counted twice.
Manual
Typed in, by the employee or by an admin or supervisor on their behalf.
Remote
A one-tap "I'm clocking in or out remotely" from the mobile app, for staff working off-site.
Only Approved entries count toward presence, pairing and payroll. A Pending entry stays visible for a supervisor to triage, but has zero effect on worked or unjustified time until it is approved. That single rule is what keeps the record honest while corrections are still in flight.
