More Info

The AllinPass K33 is the kitchen sink of the Feitian line. It carries USB-A and USB-C connectors, NFC, Bluetooth Low Energy, and an on device fingerprint sensor. It is positioned as an enterprise authenticator for environments where users move between desktops, laptops, and phones, and where one device per protocol is impractical.

The Bluetooth interface is used for paired authentication with mobile devices. NFC handles tap to authenticate. The fingerprint sensor satisfies user verification for FIDO2.

Availability is uneven. The K33 has historically been a limited release product through enterprise channels rather than the general consumer shop.
