Ittai,

Well, in nine years Farecard machines munched not my oxide, but did munch the
printer ribbons so I seldom knew how much money was left. I learned the trick
of running an unreadable card through the machine anyway. If it spit the card
back out, there was more than $2 on it. If it kept it there was less and you could get
the card back by cancelling the transaction.

The above trick is not well known and may rescue one of you someday. Try
putting a Farecard through a credit-card reader. With this I promise to shut up.
