Using Fingerprint reader in 16.04

You need the fingerprint-gui package, its installation is described at Fingerprint GUI launchpad page and reproduced below:

1. Add PP and install fingerprint-gui and other required packages

   sudo add-apt-repository ppa:fingerprint/fingerprint-gui
   sudo apt update
   sudo apt install libbsapi policykit-1-fingerprint-gui fingerprint-gui
   

2. Log out of your session and log back in.

3. Launch “Fingerprint GUI” and enrol your fingerprints.

Please note: I've used fingerprint readers on various laptops before, they are not very reliable so make sure you don't configure it to be the only source of authentication. It's best to add it on top of passwords as well or you may get locked out at some point.

For fingerprint reader 138a:003f VFS 495 this was not sufficient. Many other things had to be installed in certain ways. Refer to this for a full guide.
