Raspberry Pi connect Fingerprint Reader
Optical fingerprint readers offer large capture areas, excellent image quality and rapid capture speed all in a compact, durable case. Our optical readers with a silicone membrane provide superior image capture performance for a wide range of skin conditions. This translates to easy, efficient and high-quality image capture – which impact technology acceptance and performance – making our U.are.U readers the preferred biometric solution for a range of commercial applications.
Digital Persona U.are.U 4500 Fingerprint Reader
The U.are.U 4500 Fingerprint Reader is a USB peripheral perfect for individual desk
top users, as well as multiple users in shared environments. Its compact design
conserves desk space in enterprises, and its professional, modern appearance
looks elegant in point-of-sale environments. The U.are.U 4500 Reader utilizes optical
fingerprint scanning technology to achieve excellent image quality, a large capture area
and superior reliability. A silicone coating allows it to read a wide range of fingerprints
accurately and rapidly regardless of placement angle. The high-quality metal casing
resists unintentional movement.
To use, simply place a finger on the reader window and the reader quickly and
automatically captures and encrypts the fingerprint image before sending it to the
DigitalPersona® FingerJetTM biometric engine for verification. For superior user
feedback, a red “flash” indicates that a fingerprint image has been captured.
The U.are.U 4500 Fingerprint Reader is designed for use with a full range of
CrossmatchTM software including our authentication solutions, as well as most of our
U.are.U Software Development Kits. Whether you are an enterprise customer or a
system integrator, Crossmatch’s biometric identity verification solutions provide a natural
extension to your security system and applications.

The fprint project aims to plug a gap in the Linux desktop: 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. For more information on where we came from, see ?/Project history.
We're trying to change that by providing a central system to support all the fingerprint readers we can get our hands on. The software is open source and in the long term we're shooting for adoption by distributions, integration into common desktop environments, etc.
Software to demonstrate libfprint's capabilities.
Currently in early stages.
Written in C. Requires libfprint and GTK+.
