Abstract

A coupon management system includes a synthetic barcode phone. The synthetic barcode phone comprises light management components and a controller. The light management components include both an optical receiver (e.g., camera or light sensor) and an optical emitter (e.g., display elements). A processor decodes drive data from audio files corresponding to barcodes. The decoded data is used to drive the controller which causes the emitter to emit light pulses that emulate light reflected from a scanned barcode to communicate the coupon barcode optically.

Claims

1. A synthetic barcode phone comprising:

a light management module comprising display screen elements that emit light pulses that are sensible by a laser scanner and emulate light reflected from a scanned barcode, and a display controller that drives the display screen elements; and

a processor operably coupled to the display controller, said processor receiving analog audio signals corresponding to at least one barcode and outputting driver signals to the display controller to cause the light management module to emit light pulses that are sensible by a laser scanner and emulate light reflected from a scanned barcode

wherein the at least one barcode comprises a barcode of a coupon.

2. A synthetic barcode phone according to claim 1, wherein said display screen elements comprise one of an active matrix organic light emitting diode display and an active matrix RGB backlit liquid crystal display.

3. A synthetic barcode phone according to claim 2, further comprising an optical sensor operably coupled to the processor, said processor determining if received light pulses correspond to a barcode scanner by checking stimulus timing.

4. A synthetic barcode phone according to claim 3, said optical sensor comprising a charged couple device camera.

5. A synthetic barcode phone according to claim 3, said optical sensor comprising a CMOS camera.

6. A synthetic barcode phone according to claim 3, said optical sensor comprising an ambient light sensor.

7. A synthetic barcode phone according to claim 1, wherein said display screen elements comprise an active matrix organic light emitting diode display and said display controller comprises a thin film transistor controller.

8. A synthetic barcode phone according to claim 1, wherein said display screen elements comprise an active matrix RGB backlit liquid crystal display and said display controller comprises a backlight controller and an LCD controller.

9. A coupon management system, said system comprising:

a synthetic barcode phone comprising;

a light management module comprising display screen elements that emit light pulses that are sensible by a laser scanner and emulate light reflected from a scanned barcode, and a display controller that drives the display screen elements; and

a processor operably coupled to the display controller, said processor receiving analog audio signals corresponding to at least one barcode and outputting driver signals to the display controller to cause the light management module to emit light pulses that are sensible by a laser scanner and emulate light reflected from a scanned barcode; and

a receiver for receiving at least one coupon code from a remote source; and

a client application executable by said processor, said client application managing user selection and use of the at least one coupon code; and

wherein said display screen elements comprise one of an active matrix organic light emitting diode display and an active matrix RGB backlit liquid crystal display; and

the synthetic barcode phone includes a microphone operably coupled to the processor, and the client application is configured to detect, via said microphone, an audible signal corresponding to a successful scan.

10. A coupon management system according to claim 9, wherein said display screen elements comprise an active matrix organic light emitting diode display and said display controller comprises a thin film transistor controller.

11. A coupon management system according to claim 9, wherein said display screen elements comprise an active matrix RGB backlit liquid crystal display and said display controller comprises a backlight controller and an LCD controller.

12. A coupon management system according to claim 9, further comprising an optical sensor operably coupled to the processor, said processor determining if received light pulses correspond to a barcode scanner by checking stimulus timing.

13. A coupon management system according to claim 12, said optical sensor comprising a charged couple device camera.

14. A coupon management system according to claim 12, said optical sensor comprising a CMOS camera.

15. A coupon management system according to claim 12, said optical sensor comprising an ambient light sensor.

16. A coupon management system according to claim 9, wherein the at least one coupon code comprises a plurality of coupon codes in a queue on the synthetic barcode phone, and said client application provides controls sending a next coupon code in the queue from the cellular telephone to the module upon detecting the audible signal corresponding a successful scan.
