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

* These scanners are mostly put into use when the input cannot be brought near the scanner like heavy machinery or objects.
* The fixed position non-contact readers are best suited for applications where the items move past the scanner.
* These scanners are best suited for the mobility applications.
* These scanners can perform high-end and heavy-duty work for long durations.
