As if all this weren't bad enough...
I am seeing credit card advertisements now about a card that you can use to
make purchases by mere proximity to a card processing unit. The transaction
is 'instantaneous'. It is clear to me that John Q. Public is ignorant about
his security, and probably doesn't give a damn anyway. Take his card and
swipe a party; from the looks of it, the transaction time doesn't allow for
stolen card recovery, so once stolen the card can be used almost
indefinitely at any proximity transaction site.
This is just too stupid... What the hell are these people thinking?
Oh yeah - it's just printed money anyway, right? (wrong)
