I have an external USB-based fingerprint scanner. On MS Windows it is used to save fingerprints as images. Are there any drivers and softwares to get it working on Ubuntu?
Edit: The device I use is "Digital Persona U are U 4500"
Fprint is a project to support fingerprint readers in Linux. You can install fprint-demo from the Software Centre to get a graphical application that may be able to do what you want.
