An NFC blockchain anti-counterfeit project combines NFC (Near Field Communication) technology with blockchain technology to ensure the authenticity and prevent counterfeiting of products. By storing product information on the blockchain and using NFC technology to allow consumers to easily verify the authenticity of a product, the project effectively prevents the circulation of fake and counterfeit products.

Product information is stored on the blockchain, meaning the information is stored in a distributed and tamper-proof manner. Each product will have a unique identifier that links to the corresponding data record on the blockchain. Only authorized participants can update or modify these records, ensuring the security and trustworthiness of the product information.

Consumers can use a smartphone equipped with NFC technology or a dedicated card reader to simply tap the device near the NFC tag on the product to read the product information and verify its authenticity. This information will be compared with the data stored on the blockchain, allowing consumers to immediately determine if the product is genuine.

The nature of blockchain technology makes data tamper-proof. Once information is recorded on the blockchain, it is linked to previous data blocks and requires consensus from the majority of nodes in the network to make changes. This decentralized and irreversible feature ensures the security and reliability of the data.
