I believe that there are currently several distinct systems used for
verification of PINs. Some of them involve remote verification. Some of them
involve storing encrypted PINs on the cards. Some of them involve storing
non-encrypted PINs on the cards (indeed, most of the early systems come
under this last catagory.)

For obvious reasons, companies who issue these things are very reluctant to
dispence corect information. I've asked people at my bank on several occasions
and received several different answers.
