To implement block chain method for medical device production to verifying and tracking of medical device information. This creates a number of problems with data integrity, provenance, traceability, and openness relating to information and data about medical devices used in the healthcare supply chain. non-fungible token (NFT) based traceability system for medical devices that takes advantage of blockchain smart contracts, tokenization protocols, and a decentralized storage system. NFTs are used to represent the digital twin of the medical device. QR code were created for particular device and device details are stored in blockchain enabled server that have pre-established validation rules. All system users and stakeholders must first register and validate their identities using the suggested application. It tracks the production of medical device from manufacturers to traders that subsequently sell them to customers. Blocks of time stamped voting are stored on all systems across a value chain. Blockchain is a transaction ledger where members of a community record transfers of assets among them. The connection between two blocks is made the use of SHA-256 algorithm. Finally implement cryptography algorithm for encrypting device purchase details
