Having just been through this, a couple of points:<div><br></div><div>1) Federal law DOES cover debit cards as well. As others noted, though, you have to get the money back from the bank rather than the other way around. That can leave you flat broke until your next paycheck comes in.</div>
<div><br></div><div>2) You won't get local police to investigate. If you have something solid, however, there is someone who will. Believe it or not, primary investigative jurisdiction on "access device fraud - including credit and debit cards falls, to the Secret Service. We called them directly, and they were very happy for the info we were able to give them. The faster you move to call them, the better chance they have - cameras, etc.</div>
<div><br></div><div>3) Even though they won't help you, file a police report anyway. Your bank will require it to write off the fraud, and the Secret Service isn't officially a reporting agency, so it doesn't provide them.</div>

</div>I will have to go back and confirm this but I would be very VERY much<br>
surprised if PCI compliance allowed this sort of thing any more. The<br>
modern CVV is actually CVV2. What I've read was that CVV or CVK was<br>
permitted, by the format standard, in the discretionary fields of tracks<br>
one or two (there are three tracks but track 3 is rarely used and track<br>
two is only 1/3 the density of track 1 and can not hold nearly as much<br>
data, which isn't much to begin with) but no mention of the CVV2 which<br>
is mathematically generated from the card data (number, expiration, etc)<br>
plus a secret key known only to the provider. PCI compliance trumps<br>
what the standards allow. The clearing houses (Visa, MasterCard,<br>
Discover, Amex) impose even stricter standards. Even if the format<br>
allows it and even if PCI allows it, if the clearing house says "no"<br>
then thou shalt not. Web sites in the US are no longer legally allowed<br>
to even retain or store the CVV code, if they collect it on-line.<br>

</div>These tend to result in multiple hits though. NOBODY sells your card<br>
number ONCE. The guys that skim it that way are NOT going to use it<br>
their going to SELL it to others. That's the way it works in the<br>
underground now days. It's all business. If you only make $3 off<br>
selling a single card (and that's optimistic even for a number with the<br>
CVV) you have to sell a lot of card numbers and sell them to multiple<br>
buys to make anything. And these clowns are making a lot. If it had<br>
gone that way, he should have been carpet bombed from all over the<br>
place, not just a single chump. It doesn't fit the paradigm.<br>
