What is "finger" in libuser

[Cheng-Chia Tseng]

Hi everyone,

I am reviewing the translation on libuser for Chinese (Taiwan)
recently, and find that there is a term reading "finger information".
For example,

"Finger information changed."

I'm not sure it's about fingerprint registration or something else.
Plus, it has no developer comment for translators.

Any ideas?

Thanks. :)
