Fake Product Identification Using Blockchain Technology- Using QR Code

Manufacturing and marketing of fake or knockoff items and goods puts consumers' finances, health, and safety at risk. Through revenue loss, product slander, downtime, and replacement costs, it also negatively impacts the economic growth of original manufacturers and enterprises, compelling many brands to spend money on legal defence. The fraudulent products are detected using a camera scanner, and the QR or barcode of the item or items is connected to a block chain to save the item's information and the guaranteed unique code, which are stored as database blocks. If the code in the product matches the code in the database, a notification will be sent to the customer indicating the authenticity of the product. If the customer accepts the application's request, a notification will also be sent to the manufacturer indicating the location of the customer's purchase if the code in the product does not match the code in the database. This method of reducing fake goods ensures that customers won't just rely on retailers to decide whether products are authentic.
