RFID based push start button

[Special-Ed]

I use rfid technology frequently in the real world.

i really like the newer luxury cars with the push button to start. which some also uses rfid technologies.

anyone know of an aftermarket rfid push to start button that could be retro fit into a 67-72 gm truck with an lsx powertrain?

or heck even a blue tooth that wont allow truck to start unless it sees my cell phone.
