Abstract: A system enabling a candidate driver to start and operate a vehicle has computerized circuitry coupled to ignition circuitry and to a data repository, the computerized circuitry is adapted to sense whether an ignition switch of the vehicle is open or closed and is adapted to enable or disable ignition voltage. The computerized circuitry communicates wirelessly with a portable communication device, like a smartphone, that stores a list of identities of drivers authorized to operate the vehicle. If a candidate driver is on the list the candidate may start and operate the vehicle, if not, not.

Abstract: A system for starting a vehicle has a first apparatus having a microprocessor, a first data repository, a normally open electrical imposed between positive vehicle battery voltage and a keyed ignition switch, and a second electronic apparatus comprising a second microprocessor executing second coded instructions from a non-transitory medium, the second microprocessor coupled with the first microprocessor, a second data repository coupled to the second microprocessor and storing a list of identities of drivers authorized to operate the vehicle, and an input mechanism enabling a candidate driver to identify to the second microprocessor. The candidate driver identifies to the second microprocessor by the input mechanism, the second microprocessor, executing the second coded instructions, determines if the driver identity matches an identity on the list drivers authorized to operate the vehicle, and if so, causes the first microprocessor to close the normally open contact.
