fprint is a basic library which does all the dirty work like talking to all the different fingerprint readers and providing an abstracted interface.

Installation

Kernel

Generally speaking, fingerprint readers on ThinkPad computers are connected to the USB bus. Simply verify that USB support has been enabled in the kernel

USE flags

USE flags for sys-auth/fprintd D-Bus service to access fingerprint readers

doc	Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
pam	Add support for PAM (Pluggable Authentication Modules) - DANGEROUS to arbitrarily flip
selinux	!!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
systemd	Enable use of systemd-specific libraries and features like socket activation or session tracking
test	Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
