Geo-verified clock-in, without a biometric device
Every punch records latitude, longitude and an optional selfie, then resolves against the geofence sites you define — each with its own centre and radius. The event is stored as inside, outside or no-location, along with the exact distance in metres from the site. You get the assurance of a fingerprint scanner without buying, mounting or maintaining hardware, and it works for field staff who were never going to walk past a device anyway.
