If not a "Toll Tag" reader - is there something else that could be used to signal that an 'approved' vehicle is in the driveway? Maybe put a wifi router in the garage and have it check for a client (located in the car), and if the client is responding, disarm a security system or open a garage door? Maybe a reverse wireless pet fence, where the "fence" is in/on the car, and the "collar" is in or on the driveway?
Here's where I'm coming from:
A friend of mine has been thinking off and on about how to make his house more secure. Like all of you, he has a bunch of techie 'junk' that is valuable, most of it in his garage. He has a home security system, but unfortunately, the roll-up garage door isn't monitored. He mostly enters and exits his house through the garage door using the transmitters inside the cars. So, he sets the alarm everyday and drives to work. Then he drives home everyday, pulls into the driveway, opens the roll-up door with the garage door opener inside the car, goes in through the garage, into the house, and disarms the alarm.
Everything in the garage is essentially unprotected, especially if one of the cars is broken into.
Trying to think of ways to logically determine that when the homeowner's vehicle is present in the driveway, then allow the garage door to be opened without alarming. If homeowner's vehicle is not present and garage door opens, then alarm on.
