Transponder chips, used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit that transmits a radio frequency signals when the key is inserted in the ignition. The car detects the signal, and starts the engine only if the signal is in line with the original that was programmed in the vehicle. The car also shuts down if the frequency is not valid. This makes it difficult for thieves who aren't experienced to connect a vehicle to a hot wire and then turn it on.
The chip and the key are connected by a circuit board that includes an induction coil. When the key is inserted into the ignition it creates an electric field around the transponder. This generates a signal that is taken up by the coil before being sent to the key's identification. The key's ID number is sent back to the vehicle and if it matches the engine will start.
