What the punch actually records
When the employee taps punch in, the app requests a location fix from the phone. The operating system returns latitude, longitude, an accuracy radius in metres, and the source (GPS satellites, Wi-Fi, cell tower). The app stores these with the timestamp and, ideally, the device identifier and whether mock-location was enabled. The employer's console shows the punch on a map and, if a geofence is configured, whether it fell inside.
The accuracy radius is the number to watch. Outdoors with a clear sky, phones report 5–15 m. Between tall buildings or under a metal roof, 30–50 m is normal, and indoors the fix may come from Wi-Fi with 100 m or worse. A policy that treats every metre literally will reject honest punches; see GPS attendance best practices.
Where GPS attendance fits and where it does not
It fits any workforce without a fixed gate: security guards, housekeeping across societies, field sales and service engineers, delivery and logistics staff, construction labour spread over a large plot. For these groups the alternative is a phone call or WhatsApp message that proves nothing.
It does not work well in basements, underground parking, cold storage or deep inside large factories, where the satellite signal is absent. For these, pair GPS with QR code attendance at a fixed point, or allow an offline punch with the last known fix and supervisor confirmation. GPS is also only as honest as the phone: without mock-location detection a free app can place the employee anywhere.
- Good: guards, field sales, housekeeping, construction, logistics, remote teams
- Weak: basements, cold rooms, high-rise interiors, industrial sheds with metal roofing
- Always pair with identity (selfie/face) and a geofence rule
- Always detect and flag mock-location and rooted devices
Policy and legal points in India
Location is personal data under the DPDP Act 2023. Capturing it at punch time for attendance is a legitimate employment purpose, but employees must be told what is collected, why and for how long it is kept. Capturing location only at punch (not continuous tracking) is the proportionate default for most roles; continuous GPS live tracking should be limited to roles where it is genuinely needed, such as patrolling guards, and stated in the policy.
Put the rules in writing: which sites are allowed, what accuracy threshold applies, what happens on a geofence failure, and that fake-GPS use is misconduct. A ready GPS attendance policy template and the guide on whether employee GPS tracking is legal in India cover the wording.
A pharma distributor's 30 representatives start their day by punching in at the first chemist visit. Each punch stores GPS with accuracy; the console maps 30 pins across Hyderabad by 10:00. Two punches show 800 m accuracy from inside a mall – flagged, not rejected – and the manager confirms them by the representative's visit log. One punch has mock-location enabled and is escalated.
Attend Mitra records GPS coordinates and accuracy at every mobile punch, enforces one or more geofences per company with a configurable radius per site, flags mock-location use on Android, and combines all of this with face or selfie verification. Live GPS tracking is available separately for the security-guard module.
