Store description excerpt
Metastone service issues NFT-based genuine guarantees for real assets such as art, jewelry, and luxury goods. The authenticity certificate is recorded on the blockchain, and the issuer and transaction history are transparently verified. This trust makes it easy for physical owners to verify and prove their assets. The Metastone service consists of the Metastone app and the Metastone card. When the user touches the Metastone card on the back of the smartphone, the genuine warranty of the real asset can be easily checked on the Metastone app. The MetaStone Card safely stores the private key, which is the most important data for genuine warranty management, in a security chip inside the MetaStone Card. The Metastone card has a built-in NFC function for communication with the app. The Metastone Card is a credit card-sized card that can be conveniently stored and used semi-permanently. ● Metastone app function - Issuance of genuine guarantees for real assets such as art, jewelry, and luxury goods - Issuance of genuine guarantee based on blockchain NFT - Once issued, the NFT genuine guarantee is permanently stored in the blockchain. - Inquire about genuine warranty issuance history in blockchain explorer - Easy communication with Metastone card using NFC - Automatically launch apps using Deeplink - Multiple genuine warranty certificates can be stored ● Metastone Card Features - Store the original warranty card safely inside the security chip - Use of smart card security chip certified by EAL 5+ CC - Built-in true random number generator - Convenient storage in the size of a credit card - Semi-permanent durability - Waterproof
