For guarding, close protection and mobile posts

Prove the guard was there — and where they went during the shift.

Yendo does two things for private security. Attendance control: clock-in and clock-out from the guard's own WhatsApp, validated by GPS, device and biometrics. YENDO Tracker: an Android app that records the route while the shift is active. No batons, no NFC chips, no paper incident log.

A typical week without Yendo

  • Batons and NFC chips that break, get wet or go missing — taking the whole record with them.
  • No way to tell whether the patrol car covered the perimeter or sat parked all night.
  • Nobody can prove that person punched, and not a colleague holding their card.
  • Every new site = wiring checkpoints, installing hardware, training.
  • Hours get argued at month end over a timesheet rebuilt by hand.

With Yendo

  • Every site is a location with coordinates and a configurable radius (50 m by default).
  • The guard punches from their own WhatsApp: GPS + device + Face ID/fingerprint. Nothing to install.
  • A punch outside the radius or from another phone is still stored, flagged invalid for review.
  • With YENDO Tracker you see the full shift route on the map, not two isolated points.
  • Hours per guard and per site, exportable to CSV/Excel for payroll.
  • Onboard a new site: minutes. Add a guard: 30 seconds.

Attendance control · over WhatsApp

The guard sends a message on arrival and gets back a link. Opening it validates three things: that they are inside the site radius, that it is their phone (device fingerprint) and that it is them (Face ID/fingerprint passkey; a manager can additionally require a selfie). Biometrics never leave the phone — Yendo only receives the cryptographic confirmation. Zero install, for the guard and at the site.

YENDO Tracker · the shift route

YENDO Tracker. Android app on Google Play, built for rounds and mobile posts. The guard clocks in and the app records the route with the screen off, every 10 seconds by default (configurable from 10 s to 5 min). With no signal it stores on the phone and syncs on reconnect. Clocking out stops recording: outside the shift there is no location. The supervisor sees the shift map with current position, session blocks and device battery.

3 validation layers: GPS, device and biometrics
10s route sampling rate with Tracker
0 hardware installed per site
50m radius per site, configurable site by site

Yendo proves presence and route with exportable evidence. It does not schedule patrol rounds or replace your monitoring center — it plugs into the procedure you already run. We size coverage around the number of guards and sites you cover — get in touch and we'll work it out together.
