Getting your car stolen can be a very expensive inconvenience, there are all sorts of security devices out there to protect you car from thieves, anything from crook locks to GPS tracking systems. Today I found a Biometric Immobiliser which is kind of cool.
The biometric immobiliser functions like a standard immobiliser (i.e. immobilises starter, ignition, fuel, etc.) but instead of their being a hidden switch or combination lock the driver has to have their finger scanned before the car can be started. To prevent hot wiring all the clever electronics are hidden in an armoured-steel enclosure. So if somebody pinches your keys you can rest assured your car will be in the space you left it (provided they didn’t chop your fingers off as well :))
