+@item --card-timeout @var{n}
+@opindex card-timeout
+If @var{n} is not 0 and no client is actively using the card, the card
+will be powered down after @var{n} seconds.  Powering down the card
+avoids a potential risk of damaging a card when used with certain
+cheap readers.  This also allows non Scdaemon aware applications to
+access the card.  The disadvantage of using a card timeout is that
+accessing the card takes longer and that the user needs to enter the
+PIN again after the next power up.
+
+Note that with the current version of Scdaemon the card is powered
+down immediatley at the next timer tick for any value of @var{n} other
+than 0.
