Time to put that foil hat in your wallet!

Won't do you any good, you can get a credit card number for a card that has never been used. |

There is always a balance between security and usability. Large scale ecommerce systems for use by large numbers of consumers of different sophistication will always have some level of "shrinkage". |

A little plug for capital one...
I've had two credit cards compromised. In each case, capital one contacted me within minutes of the transactions, verified that they were fraudulent, closed my account and overnighted a new card to me. I'm pretty happy with them. |

They don't need to. You can generate card a valid card number without too much effort, the credit card companies don't just pull the numbers out of their ass  |

If they can't scan the card, how do they access info?

There are programs out there that can make it. Just like the VIN on your bike, it isn't a totally meaningless random set of numbers. It is very easy to make the card number, harder part is figuring out the expiration, but even with random guessing it still has pretty good odds. |

Give me a couple dozen stolen merchant account credentials, and I can create you an awful lot of credit card numbers. Matching the name is tricky, but generating a valid number isn't tough at all.
It's even got a nice little internal check - the digits are not random - they have a checksum designed to catch human entry errors. Swap two digits, and it won't even be a valid CC number.
And expiration dates... try every month for the next few years, and you'll find one. |
