Sorry hang on one sec. I've worked in retail for more than 20 years, and this happens every day. Whose details is it you think are recorded?? The person owning the card's details go through the system, yes, and that can be verified, but the person with the stolen card details could be anyone. They only have to have the card number (and PIN with retail purchases). Do you seriously think that thieves are going to let themselves be traced??? Yes, the stupid ones get caught, but I can tell you 50 examples from where I worked alone where they got away with it.
First, they show their face.
If you plan to make a living out of this you need to shop a lot, eventually you get caught.
Plus you need the real card, if you use cloned ones, the people behind the counter would get suspicious, online there's no such problem.
If you do this once or twice in different locations far from where you live it's fine but you simply cannot scale without getting caught.
