Understand the purpose
Buddy punching means recording attendance for another person. Identity verification can help discourage this behaviour, but no check eliminates every inaccurate record or payroll error.
Use each signal in context
Facial recognition concerns identity matching. Liveness concerns the presented sample. Location concerns where a device recorded an event. These signals have different limitations and should not be treated as interchangeable proof.
Provide a correction route
A failed identity check or unexpected location should lead to an investigation, not an automatic conclusion about misconduct. Review device conditions, the expected shift and the worker’s explanation.
Plan the people side
Explain the purpose and applicable privacy arrangements before enrolment. Establish a lawful basis, the necessary biometric condition where relevant, appropriate alternatives and a way to raise concerns. See the workforce privacy guide for the proposed framework.
