the more a fingerprint reader “allows” for oil, cuts, and any other change to the fingerprint it has stored, the more it becomes useless. the fingerprint is the key, the more the tech lets the lock change and morph the more insecure the lock becomes, and the more it will allow just about any key to work in it.

That’s exactly why I’d hope an ultrasound would ignore things like color difference. I wouldn’t expect it to ignore cuts without an ai component.
