Blockchain Based Fake Item Identification System

Quick Response (QR) codes, an emerging technology for web use cases, offer a powerful method to combat the practice of counterfeiting items. When a product's QR code is connected to Blockchain, counterfeit goods can be found using a QR code scanner. Therefore, this system may be utilized to store product information and its produced unique code as database blocks. It requests the user's unique code, then checks it against records in the Blockchain database. If the code matches, it will provide the consumer with all the product's details; if not, nothing will be displayed, indicating that the goods is counterfeit.
