With this Biometric Fingerprint Car Security System, the crooks will be stealing your car over your dead body. It attaches to the starter system of the car and prevents unauthorised starting of the car without the right fingerprint. If someone still tries it, after 6 failed fingerprint swipes the alarm goes off. You can still program it to allow up to 9 friends and family to start the car and it can be disabled via the remote control if need be. Needs professional installation but works with all cars apparently. ~US$195.
The BG11 car fingerprint security system allows authorized drivers with enrolled fingerprint to access the system in order to start their car. The BG11 is designed to be flexible in order to be enabled and disabled anytime, so you may use only your key to start your car, incase you wish to lend your car to a friend.
