A system and method of use includes a trainable transmitter trained to learn the RF carrier frequency and code of a training signal transmitted from a separate transmitter, where the code included in the training signal is a unique personal identification code associated with an individual. The RF signal transmitted fro m the trainable transmitter including the learned RF carrier frequency and personal identification code, is received by a receiver that analyzes the received person al identification code and responds thereto by performing a specific task relative to the individual identified in the personal identification code. The receiver to which the trainable transmitter transmits the learned RF signal may be a receiver installe d in a security system, in a parking location, along a toll road or bridge, or in a drive-through station of a service center, such as a restaurant or gas station. The trainable transmitter may be installed in a vehicle or provided in a key fob or identifica tion card.
