The thing I don't understand is, why use an "anything" reader on a
hand phone? I've been using hand phones since they were small enough
to be carried in one hand and I've never used a
thumb/hand/nose/anything/ reader and even more telling I've never seen
anyone else use one... in at least 4 different countries.

 
A fingerprint reader is quite convenient:
- I use the fingerprint reader as a substitute for the phone on/off
button.
- Some web sites use the fingerprint reader to speed up a web login
process.  Instead of a login, password, 2FA, wait for the text
message, and type in the 2FA number, using the fingerprint reader does
it all in one action.  I use it for login to various medical web
sites, where I usually need to login and check something in a hurry.

Yes, that's an advantage I've used quite a lot.

Unfortunately, fingerprint readers are far from perfect:

Like most "Danger!" warnings, I think that one is overblown. The hacker
would have to observe a clean fingerprint, would have to know it's from
the proper finger, then go though a multi-step process (Photograph,
process in Photoshop, 3-d print on acetate, re-cast using wood glue) to
get something that might work, might not work.

The aforementioned complicated process has the advantage of not
requiring a mold to be made from the victims fingers.  The fingerprint
image lifted from a glass or plastic object is sufficient.

Also, it's fairly simple (but expensive) to build a 3D finger print
scanner:

and print the results with a 3D printer.

The behind the display fingerprint scanners use multiple cameras and
3D scanning.  I haven't had any luck with those:

I can see the fictional characters in "Mission Impossible" doing it to
thwart an evil genius preparing for world domination. I doubt anyone
would be using it in real life to access my medical records.

Not a problem.  There seems to be an endless supply of evil geniuses
and overly curious teenagers who can break into anything.

If I wanted your medical records, I would simply go to the appropriate
department at the hospital and ask for a copy of your medical records.
That last time I did that for obtaining some test results, all they
asked for was my date of birth (because they were in a hurry).
