The YubiKey Bio - FIDO Edition is available in the USB-A format, while the YubiKey C Bio - FIDO Edition is available in the USB-C format, both with a maximum transfer rate of 12 Mbps.
The sensors and LEDs behave the same way in both formats.

The YubiKey Bio recognizes two interactions, one a touch, and the other a fingerprint. Its recognition of the fingerprint - or lack thereof - is communicated through the LEDs (see LED Behavior).
On the YubiKey Bio, the silver-colored bezel encircling the fingerprint sensor provides the grounding plane required to read the fingerprint. The bezel thus replaces the capacitive touch sensor (the gold sensor) of a YubiKey 5 series, YubiKey 4 series, YubiKey Neo, or Security Key by Yubico (SKY).
|When prompted to have the YubiKey Bio read your fingerprint from the fingerprint sensor, be sure to touch at least a tiny part of the ring. If you use your little finger to touch only the center of the fingerprint sensor, the key will not read the fingerprint.|
|Plain (Capacitive) Touch:|
|When prompted to touch the YubiKey Bio but not explicitly asked for the fingerprint, touch both the bezel and the fingerprint sensor, even though the fingerprint will not be read.|
Tips provides detailed instructions on using the fingerprint sensor.
The YubiKey Bio has a green LED and an amber LED to provide direct feedback, flashing when the key is ready for interaction or communicating something about the interaction. LED Behavior provides detailed descriptions.
