Dispute-Ready Certificates
Every session generates a tamper-evident, cryptographically sealed proof-of-work record anyone can verify.
Triple-layer verified: GPS + Movement + Device trust
Everything you need to prove your work
Six layers of verification that create an independently verifiable record of presence and activity.
Multi-Signal Verification
Device, location, movement, proximity and session activity checked together — not one weak clock-in or GPS point.
GPS Zone Continuity
Zone-level location continuity confirms the session stays consistent with the approved work area — not precision tracking.
Movement Continuity
Movement consistency helps confirm the session looks like real work. It is never used to score productivity.
Device Trust & Integrity
Sessions run on a recognised trusted device, with checks for emulator use, root or jailbreak risk, and tampering signals.
Cryptographic Sealing
Each session is chained into a tamper-evident record, so any later change is immediately detectable.
Public Verification
Every certificate carries a unique ID and public verification link — workers, employers, auditors and insurers can all check it.
Triple-Layer Verification
Three independent signals confirm every session, creating dispute-ready, independently verifiable proof.
MOV
Movement & activity continuity
Movement consistency is used as a continuity signal to confirm the session looks like real work — never to judge productivity or personal performance.
DEV
Device trust & integrity
Scello verifies the session runs on a recognised trusted device and checks for emulator use, root or jailbreak risk, and tampering signals.
Each layer independently confirms presence
How It Works
From session start to verified certificate in five simple steps.
1
Start a verified session
The worker opens the app, verifies on their trusted device, selects the approved work zone where relevant, and starts the session.
2
Capture trust signals
Scello quietly checks device integrity, zone continuity, movement consistency, proximity and session activity.
3
Build a confidence score
When signals align, confidence rises. When they conflict, the session is flagged for review — never silently changed.
4
Seal the session
Session events are linked into a cryptographic chain. If the record is changed later, the integrity check breaks.
5
Generate proof
A certificate is created with a unique ID, session summary and public verification link — portable proof for workers, audit-ready records for employers.
Built for both sides of work
Scello is designed to protect workers and give employers confidence — without surveillance.
For workers
Portable, dispute-ready proof of the hours you worked — helping protect fair pay and build a work history you carry with you.
For employers
Live session activity, compliance support, and audit-ready records across distributed teams — with privacy by design.
