+The Barcode Lookup feature allows users to quickly retrieve product information by scanning or entering
+barcode numbers. This includes details like product names, descriptions, images, categories and
+much more for UPC, EAN, or ISBN codes.
+
+This feature reduces manual data entry, improves accuracy, and enhances efficiency in retail, e-commerce,
+and point-of-sale systems by automatically populating product details in databases.
+
+Configuration

+- Fill in the required details and complete the registration process.
