Currently, QuickBooks Online doesn't have a direct connection to the barcode scanner and don't have the option to add one to the products. Although, we've got you some third-party applications that have this kind of functionality and can sync with QBO. You can go to the Apps menu in the left pane and search for any barcode scanning apps.
You may consider checking our blog website to keep you up-to-date on the feature release.
