[net.consumers] On-line VISA authorization

I've also encountered and am impressed with the on-line verification systems
for credit cards.  As noted many stores now have modified telephone sets
that can read the account number and expiration date from the mag strip
on the back of the card, so all the salesperson  has to enter is the amount.
I've also been pleased to see carbonless VISA charge slips showing up in the
NYC area (Amex, take a hint), since credit card fraud is a significant problem.
Until then -  ask for the carbons from your sales slip
           -  Do NOT give out your card # or expiration date to people who
              call claiming to be banks or credit card companies.  If they
              want to initiate communications with you, they'll WRITE.
           -  make sure YOUR card is returned to you after each sale.
and, of course, report a missing card immediately.
