Abstract
Systems and methods are provided for utilizing a work machine having a radio frequency device. The system includes a radio frequency reader that transmits a radio frequency signal over a first communication channel to the radio frequency device when the work machine travels within range of the radio frequency reader. The radio frequency device generates a trigger signal in response to the radio frequency signal, and an interface control system receives the trigger signal from the radio frequency device and performs a predetermined programmed function associated with the work machine based on information included in the trigger signal.
