> I've read that in some cases fingerprints between left and right hands can differ. I wonder if you can have more than one fingerprint stored on your device?

A fine question, but I've never heard of anyone having the same fingerprints on their left and right hands. Is this actually something that happens with any reasonable frequency?

As an anecdote, my pinky fingers are similar enough to have digital fingerprint readers reject them as "a duplicate finger", so I'm thinking the idea is that they are supposed to be unique. I've gotten a few "I've never seen it do this..." lines from the attendant and generally wind up leaving with ink-covered fingers. I'm curious if this reader winds up having the same issue.

That's what I was curious about, thanks.

Yes, it seems it supports several fingerprints.

Aren't they different in all cases where you actually have a fingerprint? They might, in some cases, be approximate mirror images, but that's still different.
