Fake Product Identification by QR code

Abstract

Counterfeit products present a serious threat to industries, consumers, and economies, resulting in financial losses, brand damage, and safety risks. Traditional methods of product authentication are vulnerable to manipulation and lack transparency. To address this, the proposed system integrates Blockchain technology with QR codes to ensure authenticity and transparency across the supply chain. Each product receives a unique QR code at manufacturing, with its details stored securely on blockchain. Consumers can verify product genuineness in real-time by scanning the QR code via a mobile or web application. This tamper-proof, decentralized mechanism reduces counterfeiting, enhances trust, improves supply chain management, and safeguards consumers. The approach has wide applications in pharmaceuticals, electronics, luxury goods, and food industries, offering scalability and reliability for future anti-counterfeit measures.
