Abstract:
Disclosed is a method of and apparatus for managing and redeeming bar-coded coupons that are displayed from a light emitting display surface of an information storage and display device, such as a cell-phone, a smart-phone, or a data communication device. The linear (1D) bar code symbols, associated with bar-coded store coupons, are displayed on the light emitting display surface using in a pulse code modulation (PCM) format, wherein a substantial portion of the pixels on the light emitting display surface are energized and de-energized to emit red-wavelengths of light energy, at a rate which temporally corresponds to the spatial frequency of the bars and spaces of the linear bar code symbol, so that a laser scanning bar code symbol reading device is capable of reading the PCM formatted bar code symbol displayed from the light emitting display surface.
