To answer Mario's original 'how they figured it out'. The $1 charge followed by a large charge is the 'tell'. That is a very common technique that criminals use to see if a card is good. They figure that $1 won't raise suspicion. And, to an extant that is true. However, $1 plus $$$ is a pretty good sign that it's fraud. Unfortunately, this sometimes results in some spurious alerts for things like an iTunes purchase followed by a Home Depot or Lowe's visit. (yup, been there). My bank has an integrated system that sends me a text message on such an alert and asks me if it is ok or not. A positive answer and they don't do anything (the charge has already happened). A negative answer and they immediately lock the card and start the process of issuing a new one. I've also had preemptive alerts on singularly large purchases where they call me after a charge has been refused for some large amount of money. Some cards (e.g. Discover) do this if you haven't used the card for a while and then all of sudden by something off of the Internet.
