Barcode scanner

Main → Settings → Barcode scanner

Everything about how barcodes get read. The first choice — the scanner type — decides which of the sections below the screen shows.

Scan with

Setting	What it does
Barcode scanner type	Camera (Mobile Vision) (the default) · Camera (ZXing) · Camera (ZXing v.2 - New!) · Camera (MLKit) · External scanner for a paired hardware scanner.

Batch mode scan

Shown for every scanner type — this is what Batch scan inside an operation does after each successful read:

Setting	What it does
After each scan	Autoincrement quantity by 1 (+1) — keep scanning, one unit per beep — or Set quantity manually, which pauses for a quantity after each code.
Scan delay (seconds)	“Delay time between 2 consequent scans when scanning to documents in batch mode” — raise it if one barcode registers twice.

When a barcode is found…

Beep and Vibrate — the scan feedback.

Camera engine sections

What else appears depends on the engine:

Engine	Extra sections
Mobile Vision	General settings — Use front light (On / Off). Camera — Rear camera preview size. Barcode detection — Barcode viewfinder width / Barcode viewfinder height, Minimum barcode width, and Enable barcode size check (“Will prompt user to move camera closer if the detected barcode is too small”).
ZXing (both versions)	“When scanning for barcodes, decode…” — 1D Product, 1D Industrial, QR Codes, Data Matrix, Aztec, PDF417 (β); the last enabled format can’t be switched off. The original ZXing adds General settings (Use front light — On / Automatic / Off — Use auto focus, Invert scan for white-on-black codes, No automatic rotation) and Device Bug Workarounds (No continuous focus, No exposure, No metering, No barcode scene mode).
MLKit	”When scanning for barcodes, decode…” — individual symbologies: Code 128, Codabar, Code 39, Code 93, Data Matrix, EAN-13, EAN-8, ITF, UPC-A, UPC-E, Aztec, QR Codes, PDF417 (β).

External scanner

Setting	What it does
Suffix (end symbol)	Scan parameters → the character your hardware scanner sends after each code: Enter, Tab, or Space — match it to the scanner’s configuration.

Good to know

• The same screen opens from the gear inside the scanning view — there it hides the scanner-type row and restarts the scanner with the new settings when you go back.
• These settings are per-device, also in StoDo Online — a phone at the counter and a warehouse tablet can run different engines.
• Scanning misbehaving? Switching the engine is the first move — the troubleshooting guide walks through it.
