However, nothing has been done to effectively apply vehicle-identifying technologies, such as bar codes, near-field communication (NFC), or transmitter identification, to these issues. Product fraud and forgeries are ongoing issues in both vending and manacles environments. This investigation identifies counterfeit items using a bar code that a Block Chain Based Management (BCBM) device uses to identify an object. As a result, the recommended device can be used to store database blocks for the product's unique code and information about it. It is possible to retrieve the buyer's precise code, which is checked against data in the blockchain database. The products are probably checked at each step of the distribution chain to achieve this. Before adding a new product to the database, the administrator generates a unique QR code for it using the SHA256 QR Code technology set of rules.
