Accept Duplicate Barcode
When this option is on, you can scan the same barcode more than once. When it is off, duplicate barcodes are shown in the Failed list on the scan screen—you can still choose to Accept a barcode from that list if you want to use it.

When Accept Duplicate is off, repeated barcodes appear in the Failed list. You can still tap Accept on a barcode in that list to use it.
