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.
