Clavis enables defense grade security outperforming all competition. It utilizes Red-Black architecture by physically separating the communication interface from the user authentication and digital signature operations. Clavis has two independent secure elements and physical tamper detection to protect your high valued assets from hackers and thieves. Clavis connects to the outside world exclusively through encrypted Bluetooth & NFC, with NFC serving as the initiator for the Bluetooth connection. You’ll always be prompted to sign with your fingerprint and password when connecting to a new device or using other features, always ensuring security.
