How to make attendance data verifiable
Verifiable attendance data means that working hours can be reconstructed, checked and explained without relying on personal interpretation.
What "verifiable" really means
Verifiable data is not necessarily perfect, but it must be:
- Recorded at the time the event occurs
- Consistent across all employees
- Protected from manual alteration
- Exportable in a standard format
Why manual processes fail
When attendance data is written manually, each correction or adjustment removes part of the original information.
Over time, it becomes impossible to determine which values reflect actual working hours and which are adjustments.
Objective data collection
Objective collection means that the system records events independently from the person who generates them.
This does not eliminate all errors, but it ensures that:
- Events are timestamped automatically
- The same rules apply to everyone
- Data remains consistent over time
Role separation
Collecting verifiable data does not replace payroll processing or regulatory interpretation. It simply provides a more reliable starting point.
Example of a technical approach
Dedicated attendance devices can generate time-stamped events that are stored and exported without manual intervention.
