Comment 4 for bug 1547040

I don’t see why System Settings needs to “obtain the number of enrolled fingerprints”. System Settings is the only access point through which you can register a fingerprint, so it can keep count itself. Even later, once the first-run setup lets you register fingerprints too, it could place an initial count somewhere that System Settings can read.

Can you explain how multiple fingerprints vs. multiple users are related? The purpose of registering multiple fingerprints is so that you can, for example, register one on each hand, to avoid having to juggle a baby, briefcase, shopping bag, or whatever you’re carrying with your other hand.

For the error messages, could you provide a complete list of possible error messages/codes returned by the reader?
