Other problem people often have that they go back to the same reader
which has already read their card 10 minutes before and which has not
read any other card in between (the other rfid card was read on the
other reader). What happens there is that the reader notices that this
is same card than last time, and ignores the card.

For user this just looks like the card is not working. What they need
to do is to use the wipe card (or any other card) and read that in and
then reread their own card.

It would be nice if the reader could be made so it does not remember
the last read card forever, but would forget it after 60 seconds or
so. 

This same problem most often hit the chairs, as almost nobody else
uses their reader than them...
