1. Understand barcode types: Confirm the barcode type on the product, commonly used ones include barcodes and QR codes. For production date inquiry, it mainly depends on whether there is a barcode or QR code containing production date information on the product packaging.
2. Use scanning tools: Use a mobile phone or specialized scanning device to scan barcodes or QR codes. In most cases, scanning will automatically redirect to the official website, product details page, or specific query page of the product.
3. Query production date: On the redirected page, search for information on "production date", "manufacturing date", or similar tags. If the page directly displays the production date, record this information. If the page is not directly displayed, it may be necessary to further search or contact the product manufacturer/seller within the website to obtain production date information.
Note: Not all product barcodes directly contain production date information, depending on whether the manufacturer encodes this type of information into the barcode. In many cases, the production date may be printed directly on the product packaging instead of being queried through barcodes.
