Knowing that Smartcards have serious security features
incorporated into them, I find it hard to believe that
this type of attack would be sucessfull against a smart
card. Take into consideration that most JAVA cards have
current sensors built into them that automaticaly reset
the card if 'unnatural' conditions occur on the card's
circuitry. Heck they even have light sensors that erase
the secure storage locations on the card, if the device
is tampered with and exposed to light. I think that
seeing is believing when it comes to this type of
attack...
