Simple or Sophisticated? Teardown of a Cell Phone SIM Card is Revealing!

Great teardown video below by electronupdate of a good ol’ SIM card – you and I likely have one if not more of these in our pockets right this very second! Electronupdate does a great review doing a side-by-side of block diagrams matched up to the layout of the SIM, and also some interesting tidbits on attacks – and therefore protections in the hardware design – against intrusion common to cellphones. Watch the video below for more!
