How to Avoid a Target-Style Credit Card Security Breach (Video)
Wayne Rash has covered IT as a reporter and editor for over 35 years. NPR, Fox Business News, and NBC all call on him as a technology expert. A few weeks ago he had an article on eWeek titled How Target's Credit Card Security Breach Could Have Been Avoided. In this video, Wayne tells how you (or your business) can avoid being targeted by miscreants out to steal credit card data. It turns out that the security measures he advocates for businesses are common in other parts of the world but haven't hit the United States quite yet. But don't despair. There are things you can do right now, as an individual, to limit your potential losses from card number thefts. Still, the long-term fixes to the security vulnerability that bit Target need to be made by merchants and card issuers, some of whom are already transitioning to cards and card readers that use EMV chips, and some of whom aren't quite there yet -- but might speed up their efforts after seeing what happened to Target.
Why don't they just go back to having to have the physical card, take an imprint of it at the register manually, and help track the usage at the stores that way?
Light travels faster than sound. This is why some people appear bright until you hear them speak.........
The reason EMV is better is because the chip allows you to sign the transaction datagram before it is sent to the bank. The chip stores the specific cards signing cert and it can't be accessed, every time there is a transaction, the pin pad sends the transaction info to the card which encodes and signs it then it is sent to the processor. NFC and other tap transactions are just as safe because even if you intercept the info you can capture the signing cert and can't duplicate the transaction.
