When I saw that film I remember thinking how outlandish it was for her to order pizza on the internet. Even if somehow that were possible, how could you just give a stranger your credit card details!? So, what, you pay a stranger and just hope your pizza arrives? Completely unbelievable.
I mean, when you give them a number on the phone, the guy at the other end is just going to be putting the number in the same place the website does.
When you pay in-store with a credit card, probably same thing.
EDIT: Well, unless, for the last case, one's using a cryptographic-signature-based mechanism, like the smartcard chip or wireless authentication. But if it's a magstrip or someone punching numbers in...
In Germany, we were behind the USA with people adopting online payment, people and companies were very skeptical about all this. I remember thinking that Germany would eventually choose to not participate in this crazy online buying trend lol
The one with Sandra Bullock? Concept-wise it was quite realistic. But the hacking itself, man that was some unbelievable stuff. I don't think they got any fact or term right.
Almost as if the OG Clippy helped: "It looks like you want to make a hacker-related movie..."
