Pen or laser scanners
November 23rd, 2009
The main difference between a CCD reader and a pen or laser scanner is that the CCD barcode scanner measures emitted ambient light from the bar code whereas pen or laser scanners are measuring reflected light of a specific frequency originating from the scanner itself. A typical Bar Code Reader kit consists of Scanner, Decoder, and Cable that interfaces the Decoder to the computer. Voltage waveform corresponding to the mobile barcode scanner bars and spaces of the bar code and sends it to the decoder is known as the bar code reader, generally called bar code scanner. CCD Barcode Scanners CCD barcode scanners use an array of tiny light sensors lined up in a row in the head of the barcode reader.
