I am guessing that there is some type of “check digit” or something similar imbedded in passive RF code in the cards that is currently not being used. The new system will use this “check digit”. When the cards were cloned this extra code was not copied. The folks that have the cloned disk in their mirrors will not work. We will find out real soon. It will be exciting to watch and read!
