What it does
- Records an arrival or departure at the moment it happens, with an identifier and a timestamp.
- Compares that record against the shift the person was scheduled for.
- Derives lateness, early leave, absence and hours worked from the comparison.
- Produces a monthly summary that payroll can use.
Why it replaces a sheet of paper
A sign-in sheet records what someone wrote down. A time and attendance system records what happened, at the moment it happened, in a form nobody edits afterwards. The difference matters most at month end, when a disputed day has to be settled.
