Configuration
Certificate
Internet connection
DNS resolution
Port 8883 (MQTTS)
TLS handshake

Changes to Employee Sync Behaviour
The Sense Clock Transaction Service version 4 introduces improved and more automated syncing between Sense HR and your clocks.
New employees are added automatically
When a new employee is created in Sense HR:
They are automatically sent to all connected clocks
A Time & Attendance ID is assigned and stored
No manual setup is required to create the employee on the clock.
Missing employees can be re-synced
If an employee is not visible on a clock:
Go to Sense HR Dashboard > People
Open the employee profile
Click More actions (...)
Select Anviz sync
The employee will be sent to all connected clocks.
Leavers are removed automatically
When an employee is marked as a leaver:
They are automatically removed from all clocks
This happens after their leaving date
No manual action required.
Optional: Sync updates across clocks
If Sync employee updates to all clocks is enabled under Sense Clock Transaction Service > Settings, updates made on one clock can automatically sync to the other connected clocks, including:
Name
Card
Fingerprint templates
Face templates
💡 Note: Biometric data is not stored in Sense HR.
When syncing across devices, only a secure biometric template (a mathematical representation of the fingerprint or face) is used — not the original image or scan.
