Automatic clock in and out

Automatic clock in and out that does not depend on a phone.

Automatic clock in and out means the worker never presses a punch. There are two ways to do it. Phone apps watch a geofence and clock the worker in when the phone crosses it. ZeroBadge uses the badge itself: power it on and the shift starts, power it off and it ends. Arriving at or leaving a site does not clock anyone in or out. It only places the minutes.

Where the shift starts

The clock-in is something the worker does with their hand, once.

A foreman reaches the shop at 5:55 AM, powers the badge on and the shift starts at 5:55. He drives to the site, hands out the day's work and never touches a punch. The shift continues through every location and ends when he powers the badge off.

Compare that with a geofence punch, which starts the shift at the moment a phone decides it crossed a line. The first approach starts when a person says so. The second starts when software infers it, and that inference is where most of the failure modes live.

Start
Badge power-on. The first report arrives within the reporting cycle, about every 5 minutes.
In between
Every report is placed at a jobsite, in transit or other, without ending the shift.
End
Badge power-off, or a flagged missing clock-out the supervisor resolves.

The tradeoff

A geofence punch is a good fit for a crew that always has charged phones, grants background location and works one fenced site. The trouble starts when any of those three assumptions fails, and on a busy morning they often do.

Three real mornings

What each approach does when the morning goes wrong.

Same crew, same 7:00 start, three different problems.

The apprentice with a battery saver
His phone is at 15% and in battery-saver mode. The app never sees the geofence, so he is clocked in when he opens it at 7:40, 40 minutes after he started work. With the badge, he powered on at 6:58 and the shift began there.
The journeyman who forgets to power on
He arrives at 7:00 and powers the badge on at 7:20 when he sees the foreman looking. The shift starts at 7:20 and is flagged as a late start. The badge has no readings before 7:20, so any correction is a supervisor's decision, logged with a reason.
The foreman who parks on the edge
The site fence is drawn from an address and the lay-down yard sits right at the line. A phone geofence can punch him in, out and in again as the reading drifts. With the badge, drift moves minutes between locations and never starts or ends the shift.

When the badge goes wrong

The badge has failure modes too. Here is each one and what you see.

The badge removes the phone from the chain. It does not remove people from it.

The badge has failure modes too. Here is each one and what you see.
What happens	What the record shows	What the supervisor does
Worker forgets to power on	No readings until the late power-on, so a late start.	Accept it, or correct the start with a reason. The correction is logged.
Worker forgets to power off	The badge keeps reporting after work. The shift is flagged as a missing clock-out, with time outside approved sites.	Set the real end time with a reason. The original run stays on file.
Badge left on overnight	A shift far longer than the crew's day, flagged for review rather than left to run quietly.	Correct the end, then remind the crew about the end-of-day routine.
Battery dies mid-shift	Reports stop at the last reading. A low-battery alert at 25% by default warns the office first.	Set the end at the last reading, or send the worker a charged badge.
No cellular signal	Reports are stored and uploaded on reconnect with their original timestamps.	Usually nothing. The day fills back in.

What it does and does not do

The honest limits of an automatic clock-in.

It is not a geofence punch
Walking into a drawn site does not clock a worker in. Geofences answer which jobsite the minutes belong to, not when work began.
It still needs a habit
The habit shrinks to one action at each end of the day: power on, power off. It does not shrink to zero.
It cannot invent minutes
If a badge was off while someone worked, there is no record to build a shift from. The supervisor can add it by correction, with a reason and a log entry.
Badges are off between shifts
Tracking runs during paid shifts on company-owned badges. Between shifts the badge is powered off and charging.

ZeroBadge AI

Ask ZeroBadge AI who has not started yet

Instead of scrolling a roster at 6:30 AM, ask. ZeroBadge AI reads the shift records your badges already made and tells you who is on, who is late and who is still running. It is read-only, and each answer links to the records it used.

You ask
Who has not powered on a badge today?
Three workers scheduled for 6:00 AM have no shift yet: two on the Elm Street warehouse crew and one at the Harbor Road clinic. None has approved time off. Each name links to that badge's last report.
You ask
Which shifts ran past the scheduled end yesterday?
Four. The badges stayed on between 35 and 80 minutes past the 2:30 PM end, three of them at Elm Street. The 80-minute shift is flagged for review as a possible missed power-off.
You ask
How many shift starts were late this week?
11 of 46 shift starts were more than 5 minutes after the scheduled start, and 7 of those came from the same two workers. Each count opens the days behind it.

Answers come only from your company's own records. Every number links to the records behind it. Read-only; admins control access.

How ZeroBadge AI works

Questions

Questions about automatic clock in and out.

How does automatic clock in and out work?

With ZeroBadge, powering the badge on starts the shift and powering it off ends it. Location placement runs in between and sorts the minutes by jobsite, but it never clocks anyone in or out by itself.

Does automatic clock-in work if the phone is off?

A phone-based auto punch does not, because it depends on the phone. A worn badge has its own battery and cellular connection, so a dead or missing phone makes no difference. See time tracking without phones.

Why does my geofence auto clock-in not work?

The usual causes are background location permission set to while-using, a battery saver that pauses location, a phone that is off or dead, or a boundary drawn too tightly for GPS to cross cleanly. Any of these can leave the app without an arrival event.

What happens if the worker forgets to power the badge on?

The shift starts when the badge is powered on, and a late start is flagged. A supervisor can correct the start with a reason. The correction is logged, and nothing is edited silently.

What if the badge stays on all night?

A shift that runs far past the crew's day is flagged for review as a missing clock-out. The supervisor sets the real end time, and the original run is kept next to the edit.

Is automatic clock-in the same as GPS time tracking?

No. GPS time tracking records where a worker was. Automatic clock-in decides when paid time starts and ends. ZeroBadge uses power-on and power-off for the second and location for the first. See geofence time tracking.
