A. If you encounter issues with barcode scanning for returns, first ensure that the barcode is not damaged or obscured. Clean the barcode area and try scanning again. If the issue persists, manually enter the return code if the software allows it, or take a clear photo of the barcode and send it to customer service for assistance.

B. As a workaround, keep a record of your return items and their corresponding barcodes in a document. This way, you can reference them if scanning fails and provide the information directly to customer service.
