Go all superspy and get fingerprint recognition for your car
When you get into your car, pop the key in the ignition and twist until the electrics begin to work. Then place your finger on the scanner and wait for the green LED to tell you that you’re allowed to use the car. If you're not recognised the car won't start.
The system itself uses wireless modules within the car to immobilise it – making the whole system nigh on impossible to find and remove if you don’t know what you’re looking for.
There are different modules available for the M10, making it compatible with any alarm or immobiliser system.
Looking at the pictures it doesn't look neat enough to be production ready, but as ideas go, it's not a bad one.....not sure what happens if it goes wrong though.
