Facial recognition

What is facial recognition?

Facial recognition is a biometric technology that identifies or verifies a person’s identity based on their face. It relies on artificial intelligence algorithms to analyze an individual’s unique facial features, such as the distance between the eyes, the shape of the nose, or the contour of the jawline.

How does facial recognition work?

Facial recognition generally follows several key steps:

• Capture: a facial image is taken via a camera or mobile device.
• Analysis: the system identifies key facial points and converts them into a mathematical model.
• Comparison: this model is then compared to a database to verify or identify the person.
• Authentication or identification: the system validates the identity if a match is found.

This technology is widely used in security, physical access (buildings, equipment), digital access (mobile devices, apps), and HR for attendance management.

What are the advantages of facial recognition in time tracking?

In an employee management context, facial recognition offers:

• Fast, contactless clock-ins, ideal for construction sites or offices.
• Reduced fraud related to identity theft or buddy punching.
• Automated traceability of attendance hours linked to tools such as time tracking systems or digital timesheets.

It is often integrated into a mobile clock-in app or a time management software to streamline planning and tracking, such as the Mobile-Punch Kiosk app.

Limitations and considerations

While practical, this technology raises some concerns:

• Privacy: biometric data collection is sensitive and regulated by laws such as Law 25 in Quebec.
• Accuracy: some systems may be less reliable depending on conditions (lighting, angle, accessories).
• Employer responsibility: the company must implement strict protective measures to secure the biometric data collected.

Frequently asked questions about facial recognition

Is it legal to use facial recognition for clock-ins at work?

Yes, but only if the company complies with applicable privacy and personal data protection laws. In Quebec, this includes applying Law 25, which requires explicit employee consent and transparency about data use.

Is facial recognition reliable for tracking work hours?

Yes, it is generally reliable and accurate, especially when integrated with robust time tracking software. It minimizes entry errors and reduces fraud.

Can it completely replace other clock-in methods?

It can replace traditional methods like swipe cards or paper sign-ins, but it’s recommended to use it alongside other tools (such as an electronic calendar) to ensure flexibility and accommodate all employee needs.
