The cards in use are made to a standard for how they operate. The reader (the 6 inch square panel on the pedestal) is constantly transmitting a "is there a card out there" signal. That tiny bit of RF energy is captured by the card, used to power up the card, and send out its long ID number. Card reader picks up that signal and sends that ID number to the gate controller computer to be processed. There are billions of numbers so security depends upon obscurity.
Then the gate controller computer compares that ID number to a list of all valid numbers in its database. If it finds that number, it opens the gate. A cloned card replies with the identical number as the original card, so everything else happens the same. We do not have the high security encrypted cards, those cannot be easily copied.
A lost card should (normally) be deactivated. Its ID is removed from the database, and if found will not match, so gate stays down. Any cloned cards also do not match and gate stays down.
Buy WHY? Since the red button allows anyone to enter, who cares what method is used to get past?
I wish the announcement was " To enhance to convenience for all residents, we will now allow any RFID card to open the gates. That includes all vehicle toll devices such as Ezpass. "
Which also begs the question... why don't the entry gates behave same as the exit gates? Overall same functionality, at a much lower cost.
