## Cross the Line. You're On the Clock.

GPS geofencing draws a boundary around each job site, then clocks crew members in automatically when they arrive and out when they leave — no tap, no app, no forgotten punches. Configurable radius, off-site flagging, and verified GPS on every entry.

### The Boundary Does the Work

Define the perimeter once and IronClock handles arrival, departure, and anything that lands outside the line.

#### Draw a Boundary per Job Site

Set a geofence around each job site — drop a pin and define the perimeter. Every site gets its own boundary, so multi-site operations stay cleanly separated.

#### Automatic Clock-In on Arrival

When a crew member crosses the boundary into the site, IronClock can clock them in automatically. No tap, no app, no action required from the crew.

#### Automatic Clock-Out on Exit

When a crew member leaves the site boundary, IronClock clocks them out. Shifts end where the work ends — no more forgotten clock-outs at the end of the day.

#### Off-Site Anomalies Flagged

Punches that land outside the boundary are flagged for review. Supervisors see off-site and anomalous activity immediately instead of finding it at payroll.

### Precise, Configurable, Verified

Tune the boundary to each site and let GPS verification and anomaly flagging keep the data honest.

#### Configurable Radius per Site

Tune each geofence to the site. A tight radius for a downtown lot, a wide one for a sprawling development. Set the boundary that matches the footprint of the actual work.

#### GPS-Verified Location

Every clock-in and clock-out records precise GPS coordinates and a timestamp. You get verified proof of where each punch happened — not just that it happened.

#### Off-Site & Anomaly Flagging

Punches outside the boundary, oddly short stays, and unexpected locations are surfaced as anomalies. Review exceptions in one place before they reach the timesheet.

#### No More Forgotten Clock-Outs

Crossing the boundary on the way home ends the shift automatically — wiping out the most common cause of timesheet corrections and missed clock-out alerts.

#### Works Alongside Smart Tags

Run geofencing on its own, or pair it with IronClock Smart Tags for a tap-confirmed punch at the gate. Use the method that fits each site — or layer both for extra certainty.

#### Stronger With Selfie Verification

Combine the boundary with selfie verification for an airtight audit trail: the right person, in the right place, at the right time, with photo and GPS proof on every punch.

### Draw the Line. Trust the Hours.

Set a boundary around every job site and get automatic, GPS-verified clock-ins and clock-outs — with off-site activity flagged before it reaches payroll. Free 60-day pilot — white-glove setup included.

## Frequently asked questions

### How does GPS geofencing work for time tracking?

You set a GPS boundary around each job site. When a crew member crosses into the boundary, IronClock can clock them in automatically, and when they leave the boundary it clocks them out. Every punch records precise GPS coordinates and a timestamp.

### Can I configure the geofence radius for each site?

Yes. Each geofence has a configurable radius, so you can set a tight boundary for a small downtown lot or a wide one for a large development. Tune each site's boundary to match the footprint of the actual work.

### What happens if a crew member clocks in off-site?

Punches that land outside the site boundary are flagged as anomalies for supervisor review. Off-site and unusual activity is surfaced immediately so it can be resolved before it reaches the timesheet, rather than discovered at payroll.

### Does geofencing work with Smart Tags and selfie verification?

Yes. Geofencing works on its own or alongside IronClock Smart Tags and selfie verification. You can layer the methods for extra certainty — a tap at the gate, an automatic boundary crossing, and a selfie all reinforcing the same verified punch.
