OThe fixed position non-contact readers are best suited for applications where the items move past the scanner. OThese scanners are mostly put into use when the input cannot be brought near the scanner like heavy machinery or objects. So, non-contact scanners can be used in almost any barcode reading application. ONon-contact readers works from a distance of several inches to several feet depending upon the scanner design and the size of the input. OCan be considered as the basic scanner when implementing for the first time. OLess in price when compared to a laser gun or a CCD reader.

&bullBenefits of Contact barcode readers:

The benefits of the barcode readers can be classified based upon their types. Barcode readers are available in several forms like in hand-held, hands-free, wearable, scan engines, laser or digital. Advanced readers use laser-scanning technology. It analyzes the barcode's image data provided by the photo conductor and sends the barcode's content to the scanner's output port. Additionally, nearly all barcode readers contain decoder circuit. It consists of a light source, a lens and a photo conductor translating optical impulses into electrical ones. The barcode scanners consist of an internal decoder and a cable, which are connected to the computer through compatible ports. These scanners come in both handheld and fixed mount configurations. These scanners use either a moving beam or a stationary beam, but mostly they have a moving laser light beam. &bullNon-contact readers: These devices need not be close to the barcode to read the code.

To read a barcode this type of readers must either touch the code or come close to it. &bullContact readers: These devices are normally held in the hands. The barcode scanners can be classified into two main categories. Thus decoding is done for the barcode and the result is sent to the output device. The space reflects the light where as the dark bar absorbs the light. When the scanning is initialized, the scanner lens reads the entire code with the help of the light source and converts the code into 0s and 1s.

A barcode consists of a series of parallel, adjacent bars and spaces that are decoded with the intensity of the light reflected by them.  Because barcode scanners are variable and include diverse capabilities, some are better suited for certain industries due to reading distance and to work volume capacity.A barcode scanner is a device that is used to read the printed barcodes.

 This converted text is delivered by the scanner to a computer software system holding a database of the maker, cost, and quantity of all products sold. The decoder interprets that signal, validates the barcode using the check digit, and coverts it into text.  More specifically, the sensor in the barcode scanner detects the reflected light from the illumination system (the red light) and generates an analog signal that is sent to the decoder. In general, a barcode scanner “scans” the black and white elements of a barcode by illuminating the code with a red light, which is then converted into matching text.  Most barcode scanners consist of three different parts including the illumination system, the sensor, and the decoder. SANDILYAM specializes in determining what type of scanner your unique business process requires, and then deploying those scanners as part of a complete solution.  Barcode scanning is the integral part of a barcoding system.
