Fake items have become more prevalent in the industrial industry in recent years. This has an effect on the company’s name, sales, and profit. Blockchain technology is used to authenticate and identify fake items. Using blockchain technology, transactions are recorded in the form of blocks in a distributed, decentralized, and digital ledger. A block cannot be changed or hacked since blockchain technology is secure. Blockchain technology eliminates the need for customers or users to rely on third parties to verify the product’s safety. In light of current advancements in mobile and wireless technologies, quick response Barcodes provide a promising technique for addressing the practice of counterfeiting (fake) in this project. This is done by scanning a Bar-code, which is linked to a Blockchain, to identify fake products. As a consequence, this method may be used to record product information and generate a unique identifier for each product in a database. It looks up the user’s unique code in the Blockchain database and sees if there are any matches. When a code matches, the client will be notified; otherwise, the consumer will be notified that the product is fake.
