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. We're trying to change that by providing a central system to support all the fingerprint readers we can get our hands on. . pam_fprint is a PAM module which uses libfprint's fingerprint verification functionality to implement a fingerprint-based login system.
