A system, method, and apparatus for communicating information in a light-based signal utilizing a fob device is disclosed. One method disclosed includes encoding transmission information data into a bar code format; generating a signal from the bar code format to simulate a reflection of a scanning beam being moved across a static visual image of the bar code format; and actively transmitting the signal as light pulses from the fob device. Alternatively, commercial information data may be transmitted to a light-based data receiving device by generating a signal from commercial information data and actively transmitting the signal as light pulses from a fob device. Transmission information data may also be transmitted from a fob device by generating a first signal from a first encoded format; generating a second signal from a second encoded format; transmitting the first signal as light pulses from a fob device; and transmitting the second signal from the fob device.
