I agree with @zax, the elekdraw is not the right tool. I also agree that a CNC does not make sense. Something "carved" into ID could easily be copied and duplicated.
There are numerous suppliers of ID cards. You are better off getting ID cards with built in security features - electronic chips, ultraviolet markings, micro-printing, magnetic strips, etc. I think you are making your end goal - secure ID cards - overly complicated. Just get ID cards with security features.
