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.
