Are you sure?

Going back a while, mid 80s when there was only one ATM in the whole of Milton Keynes, and AFAIK they were not connected to anything so they had to verify the PIN without phoning home. I seem to remember reading about a scam which involved reading the stripe with a cassette recorder, and retrieving enough info to clone and use it.

Wasn't there a case of the same card being used in two far apart cities at more or less the same time, with the bank still insisting that their system was unbreakable?
