One thing that you have to understand here Robert,its that lockout after too
much bad RFID reading CANNOT be use

if RFID become popular,and that most people come to have one RFID chip on
them,there would be million of bad RFID credential read every days.....lets
say a door of a small apartment is right on the street on a busy street like
here in downtown Montreal,and lets say that RFID reader can read from a few
feet,the chance that some people passing by the door and having RFID on them
being high,there would be readings all day long,even worst at night when
every one come home....

how would you like to have to wait a few minute before coming in your own
house?
