DUAL® is a traditional physical banknote that can interact with the CBDC. The connected banknote includes a public and a private key represented by QR codes, of which the private one is sealed. When the cover of the private key is removed, the QR code scanned, the value of the banknote can be transferred to a digital wallet.
Also, our DUAL® can act as a “face” for the CBDC and as a communication and educational tool for the CBDC-issuing central bank or issuing authority.
