Can you talk about the loopholes in the fingerprint attendance system?

I think there are at least two kinds of fingerprint attendance machines. My unit is offline, that is, it doesn't need computer attendance and system software support.

I guess what you said is online.

Cracking this thing can be said for sure, but the uncertainty is the time.

Any software has loopholes. I read an article on the internet to crack this thing, but I can't find it. I guess you want to use the internet to avoid punching in. Set a password for yourself and let others type it for you, haha.
