The Cherry Secure Board 1.0 is an ergonomic keyboard with an integrated reader for smart cards and cards/tags with an RF/NFC interface. For added security and confidentiality, the keyboard can be switched to a secure mode. Now the device can authenticate itself with a certificate and the key transmission is encrypted. This renders hardware key loggers useless and because the standard keyboard channel is locked, BadUSB attacks cannot be carried out on it. Thin clients that have the necessary software integrated are particularly suitable for using these functions. A central component of modern security concepts is the authentication of users and the authorization of access. Passwords have long since ceased to provide comprehensive access protection - they are all too easily forgotten, changed too infrequently or inadvertently disclosed to third parties due to carelessness. State of the art, especially in highly sensitive areas, is often two-factor authentication using a smart card. CHERR
