Know Exactly Who's On Site Right Now—And Whether They're Authorised
Paper sign-in books can't verify training, track hours worked, or trigger emergency alerts if incidents occur. Onos replaces paper with QR-based digital sign-in that confirms competency, captures GPS-verified attendance, and feeds accurate labour hours into safety metrics—whilst enabling SOS alerts if workers need emergency assistance.
Built For Every Role
From site workers to board members, Onos delivers accurate attendance tracking you can trust
For Site-Based Staff
Problem:
You're managing paper sign-in sheets that people forget to complete, contain illegible signatures, and provide no verification that people have required training or inductions. When the fire alarm sounds, you have no confidence that your site register reflects who's actually on site right now.
Solution:
Onos replaces paper books with QR code sign-in—workers scan the site QR code or use the mobile app, sign in with a tap, and receive confirmation. You see live attendance dashboards showing exactly who's on site at any moment. If emergencies occur, you have accurate registers for evacuation accountability.
For Office Admin Staff
Problem:
You're manually compiling attendance data from paper sign-in sheets to calculate Accident Frequency Rates, but data is incomplete (people forget to sign in), inaccurate (illegible handwriting), and time-consuming to process (4+ hours per month per site).
Solution:
Onos captures digital attendance with timestamps and GPS verification. Data flows automatically into AFR calculations and monthly site returns—eliminating manual transcription, improving accuracy by 95%, and saving 4 hours per site per month.
For Senior & Board-Level Staff
Problem:
You report Accident Frequency Rates to clients, insurers, and regulators—but if attendance data is inaccurate, your AFR metrics are meaningless or potentially understated, creating reputational risk if incidents occur.
Solution:
Onos provides auditable attendance data with GPS verification, eliminating disputes about hours worked and people present. Accurate AFR denominators mean your safety performance metrics withstand scrutiny during client audits and HSE investigations.
How It Works
Four simple steps to digital site sign-in
Deploy Site QR Codes
Each site/project receives a unique QR code linked to its location and competency requirements. Print QR codes as posters, stickers, or laminated cards and place at site entrances, canteens, and key access points.
Workers Sign In Via QR or App
Workers scan the site QR code using their phone camera (no app required) or open the Onos app and tap to sign in. The system verifies they hold required training/inductions and grants or denies access accordingly.
GPS Verification & Live Register
GPS geofencing confirms workers are physically at the site location (not signing in remotely). Site managers see live attendance dashboards showing who's currently on site, who signed in but left, and who forgot to sign out.
Emergency Alerts & Hours Tracking
Workers can trigger SOS alerts sending their GPS location to site managers and emergency contacts. Attendance data feeds automatically into monthly site returns and AFR calculations, eliminating manual data entry.
