Personally I have this fingerprint reader (Lenovo T400) for some time now (about 2 years). As I am fan of this technology I tried few times to reverse engineer its windows drivers. Problem is, that communication between OS and device is encrypted. Protocol itself is know, but to write driver for this reader, you must know how to encrypt/decrypt messages. Unfortunately as windows drivers are massive, it is work for multiple weeks 🙁 Meanwhile I use at least BIOS level power on fingerprint check - I have to pass it always when I turn on computer. BTW jelly-bears attach is always cited, but majority of new devices (and I believe AES2810 isn't exception) have support for detecting if the finger if life (heat, electric charge etc.).
