Buddy Punching

One person clocking in for another is deliberate, requires collusion, and is the case every attendance product is sold against.

What it requires

A willing colleague.

A method: a shared code, a card handed over, a phone unlocked and passed.

A supervisor who does not notice, which is the binding constraint in most workplaces.

In a team of twelve, everyone knows who is present. The problem scales with anonymity, not with headcount alone.

Where it actually happens

Large sites with many entrances and no supervision at the point of clocking.

Shift patterns where arrival is unobserved: night shifts, remote depots, contract cleaning.

Workforces with high turnover, where nobody knows who anyone is.

Rarely in small, stable teams, whatever the vendor material implies.

What each control actually does

A card or code: trivially shared. Stops nothing.

A geofence: stops clocking in from home; does nothing about a colleague already on site doing it for you.

A photograph at clock-in: effective, and it is a collection about a person's face with its own obligations.

A fingerprint or face match: effective, and it is biometric data with a higher legal bar, restricted or prohibited in several jurisdictions for attendance.

Supervision: effective, costs nothing technical, and is the control most organisations already have and do not use.

The honest ranking

For most workplaces, supervision beats technology because the person verifying is a person who knows the workforce.

Where supervision is genuinely absent — unmanned sites, lone night shifts — a technical control has a real case, and the photograph is usually the proportionate one.

Biometrics are the last resort, not the default, and regulators have repeatedly found them disproportionate where a lesser method would serve.

Removing the motive

Most buddy punching is about a few minutes of lateness meeting a rigid rule.

A punch window either side of the shift start removes the reason for most of it, at no cost.

Which is worth trying before buying anything, and is measurable: count the instances before and after.

What not to do

Do not treat every anomaly as buddy punching. Shared vehicles, covered shifts and system failures all look similar in the data.

Do not build automatic consequences on a signal this ambiguous.

And do not deploy biometrics because a vendor suggested it, without the assessment that would be required anyway.

Try the window first

The cheapest intervention, and it is measurable.

A punch window of a few minutes either side of the shift start.

Count identified instances before and after.

Most buddy punching is a few minutes of lateness meeting a rigid rule, and the window removes the motive without removing the rule.

It costs nothing and it is the control no vendor will suggest.

Follow the difficult record

Use attendance manipulation detection software to frame one representative case. The useful evidence is the record created when a value is corrected, approved and exported.
