The swIDch Fingerprint OTAC card is a physical hardware authentication device that operates without a battery by utilizing energy-harvesting technology. The card generates One-Time Authentication Codes (OTAC) locally through its built-in fingerprint recognition, enabling authentication in off-the-network environments.
The device is designed to facilitate both logical system logins and physical gate or door access control. Additionally, the card offers an optional E-ink display that can present QR codes to support varied authentication workflows.
