Read full descriptionHide full description
This app can be used to interact with physical objects which are secured by the Infineon SECORA(TM) Blockchain NFC Chip and the OwnerChip Authentication system. 1. Initialization of chips: Users can use the app to scan and initialize chips, i.e. generate new private/public key pair on the chip, create an authenticity token on the blockchain and add metadata such as title, image, description and some freely selectable attributes (traits). 2. Connect a crypto wallet: Users can connect the app to a Metamask wallet in order to prove ownership of digital twins. 3. Authentication: Users can scan an already initialized chip, the metadata of the authenticity token will then be searched for and displayed. 4. Ownership verification: Users can scan an already initialized chip, then the corresponding NFT is searched in the connected wallet and the ownership is confirmed.
