Abstract : The Proliferation of many products in the market causing problems to generate counterfeiting of products. These products are merely low-quality counterfeits of a certain brand. However, to resolve this issue many methods have been adopted to prevent the proliferation of counterfeit products such as RFID tags, Artificial Intelligence, Machine Learning etc. Nevertheless, the disadvantages of such methods are severe Ex: QR codes may be copied from QR codes that may be from real products to fake ones, and AI&ML must have high computational power. Fake products are a huge problem for companies and customers. They damage a company's reputation and trick people into buying low-quality items. To solve this, we created a system that uses blockchain and QR codes. Each product gets a unique QR code linked to a blockchain (a secure digital record). When a customer scans the QR code, the system checks the blockchain to see if the product is real. If the code does not match any records, the customer gets a warning that the product might be fake. This method is simple, and secure, and helps people trust what they buy.

Keywords : Counterfeit Products, QR Codes, Blockchain.
