During the manufacturing process, special service keys are generated within the Ring (not to be confused with wallet keys) and the public key of the Ring is uploaded to the Tangem attestation service back-end. At the time of attestation, the Ring confirms the ownership of the corresponding private key, and the public key is compared with the one uploaded to the server.",
