# PRODUCT411: Barcode config unavailable

## What this means[​](#what-this-means "直接链接到 What this means")

Barcode scanning settings could not be loaded, so scans may not match products.

The POS keeps trying to load these settings in the background. If scanning stays unreliable, reload the app once.

## What to do[​](#what-to-do "直接链接到 What to do")

Try the action again. WCPOS retries this automatically.
