Re: Security overdone

People may not be aware that in general, embedded chips are *dumb*.

In general, these things work by picking up a small amount of induced current via their aerial (the coily bit round the outside), doing something with that in the chip in the middle, and re-emiitting the result. They are only limited by the computational limits of what can be achieved with the power induced from the supplied pulse. This certainly doesn't limit them to responding with a fixed response. If they did, your RFID bank card would be trivial to clone.
