Hello,
Thanks for all explanations. For now I implemented the scd-event script
as:
...
DISPLAY=:0 export DISPLAY
if [ x$status = xNOCARD ]; then
nohup /usr/local/lib/kde4/libexec/kscreenlocker_greet --immediateLock &
while true; do
# Signature key ....: 5E69 FBAC ...
gpg2 --card-status | grep '5E69 FBAC' >> /tmp/scd-event.log && {
killall kscreenlocker_greet
break
}
sleep 1
done
fi
which works nice: on card removal it locks the screen and on card insert
it unlocks it fine.

No, you are correct, I was inprecise.
