Crap those do look real! Are they fake credit card numbers or are they using other people's accounts and then reprogramming the cards with that info? This is one of the drawbacks with technology I guess is that now dicks can go out and make fake credit cards. It's everyone else that ends up paying for their fraud in the form of higher prices and higher credit card processing fees to cover the fraud.
How to generate fake credit card numbers though that work doesn't really seems like it's even possible. Even if they successfully generated fake account numbers that were valid, I don't see how any transaction would go through with them not having a matching expiration date or credit card CCV numbers to match it. That makes me think that these fake credit cards pictured are being reprogrammed or something with real accounts.
How did they get the holograms on those though? It's not like someone can crank those out on a printer or something. Making holograms is no easy task from what I understand. This must be a sophisticated operation if they were able to get real looking holograms like that.
