Imagine
this:
A
customer—we'll
call
her
Mary—purchases
a
toy
in
your
store
with
a
credit
card.
Mary's
credit
card
information
is
temporarily
stored
in
your
computer
systems.
Fred,
your
clerk,
is a
little
short
on
rent
money
this
month.
Fred
accesses
your
computer
systems
and
steals
Mary's
card
information.
Fred
sells
that
information
to a
willing
buyer,
and
through
a
complex
series
of
transactions,
that
cardholder
information
is
eventually
obtained
by
John.
John
uses
Mary's
credit
card
information
to
go
on a
weekend
vacation
to
the
mountains.
Did
you
know
that
your
bank
will
make
you
pay
for
John's
vacation
plus
hefty
fines
($50,000,
$100,000
and
more)?
And
this
is
just
one
card—and
one
vacation.
How
much
could
this
cost
you
if
Fred
takes
information
from
many
customers
because
he's
always
short
on
rent
money?
