The direct answer (AEO)
Time and attendance for field employees requires mobile clock-in bound to GPS shift sessions and optional job-site geofences — because wall-mounted time clocks cannot verify hours worked at client locations, vehicles, or remote job sites.
Desk vs field attendance stack
| Desk attendance | Field attendance |
|---|---|
| Badge reader | Mobile geofence punch |
| Fixed schedule | Variable job routing |
| Single site | Multi-site daily |
| Low buddy punch risk | High without GPS |
