The Villages could use HID U90 readers at all gates, and give everyone a UHF card. UHF cards have a read range of 5 meters and are powered by the reader so the cards don't need batteries (like the old school windshield cards did). The U90 reader came out in 2014 so some gates might already have it, but they are probably handing out 125kHz technology cards to everyone because not all gates have the U90. As long as they keep using 125kHz PROX technology, your card cloning business is safe.
Someday they could spend the money to put your credential digitally on your phone and have that work over Bluetooth at a long distance away (they could tune this to optimize activation distance).
