Abstract: A coupon management system includes a synthetic barcode module. The synthetic barcode module comprises light management components and a controller. The light management components include an LED operating as both an optical receiver and an optical emitter. The LED receives light pulses and emits light pulses. The controller interfaces with a compatible electronic device such as a cell phone, receives codes corresponding to coupon barcodes, generates signals corresponding to light received by light management components via the LED, determines if the received light pulses correspond to scanner output, and outputs driver signals to cause the light management module to emit light pulses that emulate light reflected from a scanned barcode to communicate the coupon barcode optically. The controller determines if the received light pulses correspond to barcode scanner by checking stimulus timing (e.g.

Abstract: A management system utilizes compact, reliable, adaptable, and cost effective article identifying synthetic barcode modules, which obviate printed barcodes. The modules are programmable, detect the presence of a conventional laser barcode scanner and communicate information optically in a form readable by a detected conventional laser barcode scanner. The system is compatible with network communication, allowing real-time monitoring and updating. Additionally, the system optionally includes radio frequency identification capability, providing an alternative means of communication that does not require a line of sight. An exemplary synthetic barcode module employs a single LED as a photodiode to sense the presence of a barcode scanner and as a light source to emit light that emulates light reflected from a scanned barcode. The LED enables bidirectional half-duplex optical communication. The module may be attached to articles being tracked as well as to associated items.
