Abstract
An optical barcode and/or RFID reader having at least two sets of illuminating LEDs that are directed toward a target object to reflect whether the barcode and/or RFID reading was successful or unsuccessful. The reader is provided with a set of red LEDs and a set of green LEDs for illuminating targets, such as barcodes or RFID tags. In addition to using these LEDs to illuminate the target, the reader will illuminate the target with a particular color of light to signify a successful read, such green light, or an unsuccessful read, such as red light. A third color may be provided to indicate a successful RFID interrogation, such as blue light. The reader thus uses the built-in illumination LEDs to cast differently colored light on the target, rather than having to provide additional LEDs in a user interface positioned on the housing of the reader.
