Subject: Clear text password exposure in Datakey's tokens
 and smartcards

Well here is a cute little article about someone has hacked RFID tags for
fun. So it is good that the local library never went down that path. It 
cause great embarrament if books had their titles hacked to be "The Sensous
Librarian  --- by L"  or little notes like :  "Mutter can the cute 
librarian at works
on such and such a schedule come out an play..."  or something racey.
Perhaps I have been talking to junior high kids and teachers too much.
Here's the link:

Have Fun,
