How to stop buddy punching in your business — a practical guide

Buddy punching — where one employee clocks in on behalf of another — costs businesses an estimated $373 million per year in the US alone. If your team clocks in via a shared device, a spreadsheet, or an honor-system sign-in sheet, you almost certainly have buddy punching happening right now.

Here is a practical, step-by-step process to eliminate it in your business, whatever size you are.

Step 1: Audit your current attendance system

Ask yourself: could one employee physically clock in for another without being caught? If yes, you have a gap. Paper registers, unmonitored biometric machines, and shared login systems are all vulnerable.

Step 2: Adopt a GPS attendance app

The single most effective fix is moving to a mobile app that captures GPS coordinates at every clock-in event. Now the record includes a location — which means you can verify the employee was physically present when they claim they were.

Step 3: Set up geofences per work location

A geofence is a virtual boundary around each work location. Set the radius small enough that employees have to actually be at the site (usually 50-100 metres). Any clock-in from outside the boundary is rejected automatically.

Step 4: Enable selfie verification

Require a selfie photo at each clock-in. This closes the last loophole — an employee can no longer hand their phone to someone else to clock in. The photo attaches to the attendance record as permanent proof.

Step 5: Block mock-location spoofing

Some employees may try to fake their GPS location using mock-location apps. Choose an attendance system that detects and blocks these. Zilonex does this automatically.

Step 6: Communicate the change to your team

Announce the new system a week before rollout. Emphasize that GPS attendance protects honest employees too — they now have proof they were on time when a dispute happens.

Step 7: Review flagged clock-ins weekly

Once GPS attendance is running, spend 10 minutes a week reviewing rejected clock-ins. Follow up with employees where needed. Most rejections are innocent (wrong location, weak GPS signal) but the pattern will reveal real issues.

What to expect after rollout

Within 30 days of switching to GPS attendance with geofence and selfie verification, most businesses see buddy punching drop to zero. Payroll disputes decrease. Attendance records become audit-ready. Trust between managers and employees actually improves because every dispute has an objective record.
