What is libfprint-2-2
libfprint-2-2 is:
The fprint project aims to support for consumer fingerprint reader devices.
Previously, Linux support for such devices has been scattered amongst different
projects (many incomplete) and inconsistent in that application developers
would have to implement support for each type of fingerprint reader separately.
The idea is to change that by providing a central system to support all the
fingerprint readers as it’s possible to get hands on.
libfprint is the centre of efforts, this component does the dirty job of
talking to fingerprint reading devices, and processing fingerprint data.
This library depends on the new libusb, which performs asynchronous callbacks,
allowing fprint to perform non-blocking device tasks.
This package provides shared libraries.
