Biometric Time Attendance Explained

From the fingerprint or face at the door to the report that feeds payroll: how a biometric attendance system works end to end.

In this guide you will see:
  • Biometrics stop 'buddy punching'.
  • The terminal records punches; the software turns them into hours.

Quick answer

A biometric attendance system records when each employee clocks in and out using a fingerprint or face, so nobody can clock in for a colleague. The terminal sends punches to attendance software, which applies shift rules, calculates lateness and overtime, and produces reports or payroll exports.

05Frequently asked questions

Can staff clock in for each other?

Not with biometrics: the fingerprint or face has to be the employee's own.

Does the terminal need internet?

Not to record punches. It needs a network connection (or manual download) to send them to the software.

Can it export to payroll?

Most attendance software exports hours in formats payroll systems or spreadsheets can use.
