Integrated Fingerprint Reader
IBMs second generation of T42 models (released in Autumn 2004) was the first to feature an integrated fingerprint reader. Various models since then have had this feature, actually implemented with a number of different devices, all of which appear on the USB bus. Some are just scanners, others do the recognition in the device itself.

Read more about the various models of reader on the libfprint wiki
Also check the Fingerprint-GUI PPA which has a detailed list of supported devices. Be aware this PPA includes non-free software as indicated in the About page of the project.
The UPEK device is supported by thinkfinger. Those devices and Authentec ones are supported by libfprint.
However: The fingerprint reader is an INSECURE device and gives a false sense of security! There has been quite a bit of research by a hacker named Starbug, a member of the Chaos Computer Club, Berlin, Germany. He outlined in two very good talks how to forge each and every available fingerprint sensor available at the cost of a few euros, using materials from your local hardware store, a digicam and a laser printer! Here's some links:
Remember, using fingerprints for authentication is much similar to having a password which is written on anything you touch.
