Dave, I entered a NYC office building the other day and as usual
nowadays had to sign in and get a little badge printed out for me,
which authorized me through the turnstile.  A wrinkle I hadn't noticed
before:  guy took my driver's license (from another state) and dipped
it in a reader slot, studied his screen readout a bit but didn't type
anything, just pushed a couple of buttons, and out printed a badge
with my name correctly spelled.  Suggests at least that they're
reading driver's license data directly; now, question is, if there
were a police officer in Kansas (a state I've never visited or had
business in) who really wanted to talk to me, would he know by now
that I was in that building the other day?  The capacity is certainly
there.
