Having trouble scanning a barcode in Katana’s mobile apps? Here are the most common reasons why a barcode might not be recognized — and what to do about it.

Note: Barcode scanning is available in the Shop Floor App and Warehouse App. Each app supports specific barcode types depending on the task (e.g. picking, receiving).


Why a barcode might not scan

The printed label is damaged or misaligned

  • The barcode may be partially cut off, faded, or printed outside the margins.

  • Fix: Reprint the barcode, ensuring it's centered, clear, and fully visible.

The barcode registered in Katana is incorrect

  • If the wrong barcode is saved in Katana, the system won’t recognize it when scanned.

  • Fix: Double-check the item's barcode in Katana’s product or ingredient card.

You're scanning an unsupported barcode type

  • The barcode you're trying to scan might not be accepted in that specific context.

    • Example: Scanning an internal barcode during a receiving task in the Warehouse App. Only supplier barcodes are supported there.

  • Fix: Make sure you’re using:

    • Registered barcodes during Pick & Pack (Warehouse App)

    • Supplier barcodes during Receiving (Warehouse App)

    • Registered item barcodes for ingredient tracking (Shop Floor App)


Tip: Use a dedicated scanner

For more reliable results, especially in high-volume environments, consider using a dedicated infrared barcode scanner (handheld or built-in). These tend to be more accurate and faster than using a smart device camera.
