The increasing prevalence of counterfeit products in various industries poses significant challenges to consumer safety, brand integrity, and economic stability. This paper proposes a novel approach to combat counterfeit goods by integrating blockchain technology with barcode scanning systems. The authentication and traceability of products can be verified securely by assigning a unique barcode to each product and linking it to an immutable blockchain ledger. Product information, such as manufacturing details and distribution history, cannot be tampered with because of the decentralized nature of blockchain. The system permits consumers and retailers to scan the barcode using mobile devices or scanners, resulting in the instant retrieval of verified product data from the blockchain. Product security, transparency, and traceability throughout the supply chain are enhanced by this solution, which empowers users to effectively identify counterfeit products. The proposed system has a robust mechanism that prevents counterfeit goods, increases consumer trust, and ensures the integrity of global supply chains.
