Barcode Scanner Features
Barcode Scanner is composed of three parts like Illumination system, Sensor/Converter and Decoder.
- Illumination system consists of a red beam of light which is to be enlighten on barcode.
- Sensor detect beam of light reflected from illumination system which in turn creates an analog signal.
- Converter switches produced analog signal into digital one and transmit to decoder part.
- Decoder read between the lines of digital signal, carried out mathematical computations, check barcode is intelligible or not, modifies into ASCII text and send it to the PC to which the reader is attached.
