The gates use a computer based access control system to control the gate. The reader, the 11"x11" square on the pedestal made by HID, transmits a 900 MHz signal. The transmitted signal induces a voltage in the access card which powers up the chip in the card. The chip then transmits a 26 to 38 bit badge number to the reader. The reader receivers the badge number and passes it to a controller which makes an access decision. The entire process takes about .2 seconds.
There is an active card available that has an internal battery made by HID that can be put on the inside of the windshield and will transmit 6-8 feet instead of the 12" of the current prox card. Unfortunately the card manufactures do not sell to end users, only to integraters, and then in minimum lots of 10 for the active cards at about $22 each (dealer cost). Not cost effective unless The Villages decided to sell them.
I'm still actively employed in the security business and have decoded my two cards. I can create clones of the passive cards but ordering the active cards is limited because each customer has a unique facility code that is only sold to a registered supplier for the end user (the villages).
As you can see, pretty much a dead end.

Thanks for the explanation. Sounds like that is also the technology used in the SunPass transponders. Florida is/has phased out the battery powered ones. I have wondered how they could send a signal without power.
