🤖 AI: 1 anomaly detected
Tracking time for 150,000+ employees across Vietnam & SEA
Manual attendance costs
you more than you think.
Buddy-punching costs 2–8% of annual payroll
Employees clock in for absent colleagues. Without biometric or AI verification, it's undetectable.
Manual timesheets take 3 hours/week per HR person
Cross-referencing spreadsheets, chasing approvals, fixing errors — before payroll even starts.
GPS check-in fraud at construction & field sites
Employees fake location, claim hours worked at sites they never visited.
Compliance risk from inaccurate overtime records
Vietnam labor law requires precise overtime documentation. Manual records invite disputes and fines.
