CCD Barcode Scanner

CCD barcode scanners are camera-based readers existing in the market today. CCD stands for Charge Coupled Device and it is a newer technology adopted by pen or laser barcode readers. The CCD scanners work just like the camera scanners. The head of these scanners is loaded with an array of light sensors that analyse the intensity of light from the barcode labels. The most important dissimilarity between camera and CCD barcode readers is the light frequency replicated off the barcode labels. The CCD scanners automatically pick up the image of the label.

The uses of CCD scanners are complex than the basic laser scanners. Major applications that handle gift card, debit and credit payments are usually swiped through the CCD barcode readers, which could read the magnetic stripes located at the back of these cards. They are also used to shift track employees for security purposes at public events and universities.

Some of the other advantages of these readers, as compared to the laser readers, include the scanning of complex applications with complete accuracy. The newer scanners that employ the CCD technology would allow the users to read smaller barcodes with the highest level of efficiency and therefore it simplifies the pricing of the smaller items. There are very less chances that a barcode wouldn’t be read. This helps the industries to maintain their inventories accurately.

The only disadvantage of CCD barcode scanners is that they have a problem reading the wider labels. Another concern prevalent about such scanners is that they cannot usually function further than 3 inches of distance from the barcode. Therefore the barcodes have to be brought closer to the reader for each scan.
