Attendance tracking: cards, fingerprints or face recognition

Contents

In many companies attendance tracking begins with a timesheet and ends with one.

A department head fills it in at month end, some days have to be recalled, and lateness is not recorded at all. The accountant then calculates payroll from that sheet, and the objections begin.

The problem is not the calculation. It is that the data was never captured.

The short answer

There are three methods: cards are cheap but unreliable, fingerprints are reliable but awkward on a shop floor, and face recognition is contactless and unaffected by gloves. In manufacturing and services the third is usually the most practical. A system including a terminal runs $7,000–12,000 over three to four weeks.

Comparing the three methods

A comparison of three attendance tracking methods

Criterion	Card	Fingerprint	Face recognition
Reliability	Low - can be passed on	High	High
On the shop floor	Works	Dirty hands or gloves are a problem	No problem
Speed	Fast	Moderate	Fast
Hygiene	No issue	Requires contact	Contactless
Hardware cost	Lowest	Moderate	Higher
Risk of loss	Cards get lost	None	None

Cards suit a small office, but in a plant they lose their meaning - passing a card to a colleague is easy and the habit spreads quickly.

Fingerprints are reliable but do not work in shop floor conditions. Hands are oily, dusty or gloved. In food production, hygiene requirements add a further obstacle.

Face recognition is therefore the practical answer in manufacturing and services. Our own Face ID System works this way and is used by over 20,000 people.

More than arrivals and departures

Many companies see attendance tracking as an answer to "who arrived when". In practice it closes four other problems.

Payroll. Hours are calculated automatically and the timesheet disappears. That saves finance two to three days a month.

Overtime. When an employee says they worked Saturday, there is now a record confirming it. That works in the employee's favour - a verbal claim could previously be dismissed.

Access control. Who can enter which area. Warehouse, cash office, server room - each with its own permission.

Safety. In an emergency it is known exactly who is in the building. Many companies never consider this, and it is a serious matter.

Linking to payroll

The real benefit appears when the system does not stand alone.

The link works like this: the terminal records arrival and departure, the system calculates working hours, and the payroll module produces the figure from them.

The rules are defined in advance:

Start and end times of the working day
From what point lateness counts - ten minutes, for example
Whether the lunch break is deducted from hours
How overtime is approved and how it is paid
How sickness and leave are recorded

Without these rules the system produces numbers, but how to apply them becomes a monthly argument.

The most common mistake

Switching the system on and applying deductions in the first month. Lateness becomes visible and immediately affects pay - resistance starts the same day. In the first month let data accumulate without consequence. That gives people time to adjust and it saves the system.

Working with staff

This matters more than the technical side. Of all systems, attendance tracking provokes the most resistance.

The reason is plain: lateness is now visible.

What works:

Announce the rules in advance. At least two weeks before switch-on. How lateness is counted, where the threshold sits and what happens in the first month - say it openly.

Show the upside. Overtime is now confirmed by a record. No timesheet to fill in. Employees can see their own hours.

Release the portal early. When employees can see their own data, the system reads as transparency rather than surveillance. Objections fall after that point.

Management uses it too. If a director stays outside the system, staff notice immediately and treat the rule as unserious.

Data privacy

Face recognition works with biometric data, which requires separate attention.

Practical requirements:

Requirement	What it means
Employee consent	Written consent before the system goes live
Storage location	Data on your server or an agreed location
Access rights	Who can view it - limited by the role system
Retention period	How long it is held and when it is deleted
Leavers	What happens to a departing employee's data

These requirements are set in law and can change. Confirm the current position with your lawyer before implementing.

How the rollout runs

Write the rules

Working hours, lateness threshold, overtime approval. This is management work and it happens before the system.

Terminal placement

Choose the entry point. The number of terminals is calculated by headcount so that no queue forms.

Enrol the staff

Each employee is registered. With face recognition this takes a few minutes per person.

Trial month

Data is collected and reconciled against the timesheet, but does not affect pay.

Link to payroll

Hours flow into the calculation automatically. Timesheets stop.

The second step is skipped most often. If two hundred people pass through one terminal, a queue forms every morning and it breeds resentment. One terminal per sixty to eighty people works in practice.

What to measure

Record at the start of the project and measure again after three months:

Metric	Why it matters
Days spent on payroll	Usually falls from two or three days to a few hours
Objections per month	A measure of trust
Average lateness in minutes	Usually drops noticeably in the first month
Time spent filling timesheets	Time taken from department heads

The third is interesting: lateness usually falls as soon as the system is switched on, even with no deductions applied. Visibility alone has an effect.

What it costs

$7,000-12,000On a ready system, with payroll linked, 3-4 weeks

Terminal hardware is a separate cost and is not in the price. Face recognition terminal pricing varies by model - ask about it separately when you receive a proposal.

If you already run an ERP, the attendance module is added inside it, which costs less.
