Jeff, Yes Fortezza cards can be instructed to produce a random number through one of its library calls (someday they'll have a real API). One of the diagnostic tools I had tested this function. What algorithm do they use? Haven't a clue. Sources say that the RNG implementation may vary from vendor to vendor (i.e., GTC, Spyrus, Mykotronix, etc.).
