Abstract:
A barcode scanner, comprising:a scanner engine to produce a barcode scan pattern and receive reflected light produced when the scan pattern falls on a barcode, the scanner engine producing a barcode signal in response to the reflected light; a decoding circuit for decoding the barcode signal to extract barcode information; a user selection device for receiving a user input and producing user selection information for use in selecting a desired operational state of the scanner; and a processor receiving operator selection information from the user selection device and barcode information from the decoding circuit, the processor controlling the scanner engine to select a scan pattern to be produced by the scanner engine in response to the operator selection information, the processor being operative to receive and register barcode information from the decoding circuit, the processor being operative to control decoding of the barcode by the decoding circuit, the processor being operative to prevent or allow decoding of the barcode in response to user selection information such that if a user selection is made to prevent decoding of the barcode, the decoding circuit can receive a barcode signal produced by reflections of the selected scan pattern from a barcode without decoding the barcode signal.
