GPS-verified attendance

Attendance proved by location, not by trust.

A merchandiser opens Pabasa inside the shop. The phone reports its fix and how accurate that fix is; the server decides whether that puts them in the building. No message at month end, no argument about who was where.

Verdict
Server-side never the handset
A check-in judged against an adaptive geofence An overhead view of a terrace of shops. The middle unit is outlined. A solid ring marks the shop's own 25-metre radius and a larger dashed ring marks the 38-metre effective radius, widened because the phone reported its fix as accurate to only 12 metres. The phone's position sits inside the shop outline, so the check-in is confirmed. 25 m · shop 25 m · shop 38 m · effective 38 m ±12 m fix

Passed
One check-in, as the server judged it. The outer ring is not a fixed fence — it is 1.5 × what the handset said its own accuracy was.
Signals
  • GPS fix + reported accuracy
  • WiFi points recorded for the shop
  • Bluetooth beacons
  • Serving cell identity
  • Device attestation

GPS is the proof everywhere. The rest only raise it or challenge it.

01 The circle

The circle knows how good the signal is.

Indoors, a phone is less sure where it is. The circle grows to match, so a weak signal never costs anyone their hours.

  • Good signal

    Small margin of error. The circle stays the size of the shop.

    Confirmed

  • Weak signal

    Bigger margin of error. The circle grows to match it.

    Confirmed

  • Not in the shop

    Outside the circle either way. A manager decides.

    Needs approval

02 Hard places

Built for shops with nothing.

  • No WiFi neededGPS on its own is the proof.
  • Works offlineCheck-ins wait on the phone and upload later.
  • Almost no dataIt has to last a month on their own bundle.
  • The phone never decidesOur servers do, so the app can’t be talked into saying yes.

03 The month

The timesheet writes itself.

Every line came from a real arrival and a real departure. Nobody typed a time.
