T.J. Maxx probe finds broader hacking

Federal authorities say they have cracked what appears to be the largest hacking and identity theft ring ever exposed.
(From The New York Times)
The story "11 charged in theft of 41 million card numbers" published August 6, 2008 at 6:57 AM is no longer available on CNET News.

Can we please finally replace them with smart devices that use internal electronics to do public/private key encryption or something similar SO THAT THE DEVICE CANNOT BE USED WHEN NOT PRESENT AND CAN NOT BE DUPLICATED UNLESS THE ORIGINAL DEVICE IS STOLEN? Like I've said before, a simple encryption device that contained a private key that never ever ever ever left the device could digitally sign transaction data that could be authorized by a bank computer that contained the matching public key. It would be just a simple device to digitally sign your transactions like a smart card or something else. Strap a USB adapter on it and net shopping away you go.
The middle man such as Walmart's terminal device or Amazon's network would never see this key. Therefore someone hacking Walmart's network couldn't dup your card because even Walmart doesn't know your key. All it sees is the signed transaction that gets shuffled off to the authorization server that ALSO doesn't know your private key. Even the computer that authorizes you would be totally clueless. It would only have the matching public key that verifies the transaction was indeed signed by your device. Even bank computers get compromised so their computers cannot know you're secret number either, but the math on how to do this is already known.
This would eliminate the ability for people to steal thousands of credit card numbers at a one time. The only way to get the private key would be to steal each device separately. As soon as your reach in your pocket and realize it has been stolen you make a call to the bank and deactivate it. Then simply get issued another one with a new private key built in. The criminals would have to steal one at a time and they'd only work for a day or two. How much crime would that end?

- I agree with Imalittleteapot. A public/private key would work much, much better.
