Time Clock

Time tracking that can't be faked

Every punch gets a server timestamp, geolocation and a chained hash no one can alter. And overtime lands in payroll automatically.

Real verification

A record that holds up

No editable spreadsheet: every punch is sealed and can be re-verified at any time, with a full tamper-evident chain.

  • Timestamp set by the server — never by the employee's device
  • Sequential number + tamper-evident SHA-256 hash chain
  • A hash receipt handed to the employee on every punch
  • Re-verify the whole chain in one click

A time clock that works for you

From punch to payroll, no rework.

Punch in seconds

Clock in, out and breaks from web or phone, in one tap.

Tamper-evident

Hash chain and sequence numbers prove no record was altered or deleted.

Overtime in payroll

Tracked hours become overtime automatically in each country's calculation.

Geolocation and IP

Every punch stores location, IP and device — real proof of presence.

Web and mobile

Works in the browser and on the phone, nothing to install.

Audited corrections

Forgot to punch? The fix is a new traceable record — the original never disappears.

How it works

From punch to payroll in 3 steps

1

The employee punches

From the portal or phone. The server stamps the time and captures location.

2

The system seals it

Sequential number + chained hash. The employee gets a receipt.

3

Hours flow to payroll

The period's overtime is computed and applied automatically.
