Hi,
Thanks for the answer but
all these 03 points are correctly verified.
But it should also be noted that I imported my items into the inventory section.
Initially some items came up when I scanned but then nothing.

Hi,

Please check out the below points
1) Check Barcode Configuration.
. Go to the Inventory module and check that each product has a barcode assigned to it.

2)  Barcode Format
. Confirm that the barcode format from your reader is compatible with Odoo. Odoo typically supports standard barcode formats such as EAN-13, UPC-A, etc. Ensure that the barcodes scanned match the format expected by Odoo.

3)  POS Barcode Configuration.
.  Make sure that the barcode scanner is properly configured in the POS settings.

Hope this helps.
