Using the device

Enhanced plan

This page is the operator’s side of Label Checker — what your warehouse staff see once they open a session on a tablet or phone. Use it to understand the device workflow and to train operators.

Logging in

When the device opens a session, the first thing the operator does is identify themselves. There are two cases, depending on whether you’ve assigned operators to the session:

With operators assigned (PIN gate). A “Who’s scanning?” screen asks the operator to pick their name and enter their 4-digit PIN, then tap Unlock scanning. The PIN is checked on the server. After 5 wrong attempts in a minute, the device shows “Too many attempts. Wait a minute and try again.”
Without operators (name only). The operator just types their name and taps Start scanning — no PIN.

Either way, every scan is attributed to whoever is signed in. A badge in the corner shows their initials, with a Change operator option to hand the device to someone else.

If you’ve set a re-login timeout, the PIN gate reappears after the device has been idle for that long.

Scanning

The operator points the camera at a barcode (or uses a hardware scanner). A match plays the success sound and adds to the on-screen tally; a miss plays the failed-scan sound. The tally lists each item with its running count.

Runs

A run is one batch of scanning — a box, a pallet, a delivery. The operator:

Taps Start run to begin.
Scans items into the run.
Taps Finish run to close it. A dialog confirms “N scan(s) will be saved to this run. The on-screen tally then clears for the next run.”, and lets them add an optional run name (e.g. “Box 12 / Pallet A”) and notes before Finish & save.

Finishing a run is non-destructive — it’s saved, and the screen clears for the next batch. Each run appears separately in Scan statistics.

Standard vs. target mode

Standard — straight label-checking against the expected list.
Target — counting toward a target quantity per item.

Switching mode while a run is open prompts “Switch to … mode?” with three choices: Finish & save the current run, Keep open to park it and resume later, or Cancel. If a target session is already parked, entering target mode offers to Resume it or start a New session.

Adjusting counts

Each item row has a stepper: − / + to change the count by one, or tap the number to type an exact value. A trash icon removes a row from the tally. To start a batch over, the operator finishes the run and starts a fresh one.

Working offline

The device is built for unreliable warehouse Wi-Fi:

Scans keep working offline. Each scan is saved on the device and counted on screen immediately, then synced automatically when the connection returns (and periodically in the background).
Nothing is lost on reload. Scan data is stored on the server against the session, so reloading the page, reinstalling the app, or a dropped connection won’t wipe the tally.
If a sign-in expires mid-shift, an amber banner appears — “N scan(s) pending — sign in again to sync. Your scans are saved on this device.” — with a Retry sync button. The queued scans flush once the operator signs back in.

Reviewing past days

From the device, the operator can open Run history to review earlier work:

Runs are listed newest-first with a status — Active, Parked (open, resumable), or Finished / Auto-closed.
Opening a run shows its totals, lets the operator edit the run name and notes inline, and offers Resume run for parked runs.
A per-day rollup shows the day’s totals and a per-item tally. Past (closed) days are read-only; the current day updates live.
The operator can export runs from the device — Full stats or Scanning history, as CSV or Excel, for one run or several selected at once.

This is the same activity you can review and export from the admin in Scan statistics.

Installing to the home screen

The device app is installable. Using the browser’s Add to Home Screen (or the Android install prompt) adds it as a standalone, full-screen app named “Scanner” — no browser chrome, portrait orientation, ready to reopen with a tap.
