Multi-Signal Verification
Device, location and session activity are checked together today, with movement and Bluetooth proximity planned — not one weak clock-in or GPS point.
For contractors and business
Built to protect both sides of work
Whether you protect your own hours or manage the teams that deliver them, Scello gives you stronger proof that work happened.

For Business
Live visibility across your workforce with dispute-ready, audit-friendly records.
- Live workforce visibility across every site and zone
- Fewer disputed hours and cleaner payroll
- Audit-ready, independently verifiable records
Dispute-Ready Certificates
Every session generates a tamper-evident, cryptographically sealed proof-of-work record anyone can verify.
Verified: GPS-recorded on a recognised device
The trust engine
Everything you need to prove your work
Six layers of verification that create an independently verifiable record of presence and activity.
GPS Zone Continuity
Zone-level location continuity confirms the session stays consistent with the approved work area — not precision tracking.
Movement Continuity — Planned
Scello is designed to add movement consistency as a continuity signal without scoring productivity. Production collection is not active today.
Device Trust & Integrity
Sessions run on a recognised trusted device, with device trust scoring and tamper-evident hash-chain integrity.
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.
How the signals combine
Triple-Layer Verification
Three independent signals are designed to confirm every session — GPS is live today, with movement planned — creating dispute-ready, independently verifiable proof.
GPS
Location continuity
Scello verifies the session stays consistent with the expected work zone. It is designed around zone-level continuity, not unnecessary precision tracking.
MOV
Movement & activity continuity
Movement consistency is planned as a continuity signal to confirm the session looks like real work — never to judge productivity. Production collection is not active today.
DEV
Device trust & integrity
Scello verifies the session runs on a recognised trusted device, with device trust scoring and tamper-evident hash-chain integrity.
Designed so each layer can independently confirm presence
The user journey
How It Works
From session start to verified certificate in four 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
Signals confirm context
Scello checks device integrity, zone continuity and session activity. When signals align, confidence rises; when they conflict, the session is flagged for review — never silently changed.
3
Seal the session
Session events are linked into a cryptographic chain. If the record is changed later, the integrity check breaks.
4
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.
The opportunity
Weak proof is expensive
Billions
Industry estimates point to widespread disputed and unpaid wages across modern work — far beyond any single industry
Many
Gig and contract workers lack verifiable proof of the hours they worked
Scello transforms unverifiable manual attendance into cryptographically sealed, dispute-ready evidence.
