Which may be then used in the product this QR code and the NFC acts as a digitalized invoice for the product. Where the customers can confirm the product or can look at the product both through scanning the QR code or through scanning the NFC tag to get product details. The smart contracts are constructed using solidity and the deployment became completed using Truffle blockchain deployment tool. The authentication capabilities became deal with the use of firebase via which are able to capable of see the numbers of customers authenticated and different such analytics. The intention of the entire challenge became to lessen fraud and product tampering with inside the supply chain management.
