Um .. that's exactly the problem smartcards attempt to address. It's highly unlikey you'll be able to copy the protected contents without resorting to a timing attack or the like (and that has been addressed lately as well). If you're really patient, you could decapsulate the chip and read the eeprom contents with a microscope .. but that sort of defeats the purporse as you've destroyed the original. As to your other question, a .hex file is just a binary image. ~Mike.
