I lived in a gated community down in Naples with a great system.

Bar coded sticker was placed on the passenger side rear window. As you approached the gate a scanner sensed the sticker and the gate opened.

Here in TV the sticker could be placed on golf carts as well as cars, maybe bikes and motorcycles. No more searching for the card, rolling down the window, etc.

Stickers are probably less expensive than the cards and you're not going to misplace something stuck to the side of your vehicle.
