How to enable finger printer with Thinkpad X230

I am a newbie with Ubuntu and Linux, and I just switched from Windows 8. I have installed 12.04 on my new Lenovo Thinkpad x230. It seems everything else works perfectly except the finger printer. I have been using Finger Printer for a long time, and I really rely it on for my Lastpass application. But I don't know how to enable or install the driver of the finger printer. Can anybody help me with this?

Thanks in advance.
