Pretty cool - You could also offer "stealth" chips - in rings, necklaces, watches, bracelet, shoes, cigarette lighter, cigarette pack holder, cell phone cover, etc - something (or place) a car thief probably wouldn't look for. Or a picture card that will only activate if you touch a series of graphics in the right order. Butterfly, rainbow, dog, wrench, then it starts - if not - it won't start. Otherwise, anyone who has the card can take your car.

Love it - You rock!
