1. A method of providing transmission information to a bar code scanner from a mobile digital device comprising a display screen having a variable light level, comprising:
- providing transmission information as bar code formatted transmission information in the device;
generating in the device a signal from the bar code formatted transmission information to simulate a reflection of a scanning beam being moved across a static visual image of the bar code format; and
controllably varying the light level of the display screen to transmit the signal as light pulses from the display screen.

Abstract
A system, method, and apparatus for communicating information encoded in a bar code format between a mobile communications device and a bar code scanner. Transmission information data is encoded into a bar code format. A signal is generated 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 the signal is transmitted as light pulses from the mobile communications device.
