I wonder, though, couldn't they also get the numbers and info on the new radio frequency cards before they ever hit your mailbox? I mean, scan it through the envelopes, and wait a few days to use it until they figure the real CC owner has activated it. I wonder what type of security on those transmitter cards they use during mailing.
I know I can pretty much tell when the envelope arrives in the mailbox whether there is new CC in it or not.
Just pondering other ways that this could happen. Fortunately, the only actual fraudulent charges I've ever had were cases of the machines not working properly (double charging) from the real places that I used it.
