OK.  I will try to improve Poldi this month.  My plan is doing
two things.

(1) As you pointed out (and we agree): a change of Poldi

Always require user's PIN input.

(2) Adding a command to scdaemon so that an application can be notified
    for card removal.

Currently, we have "scd-event" feature, but it is not well-designed.
I'm thinking about adding WATCH command which informs status change.

I'll report about changes here.
