Barcode scanners introduction


A barcode reader or scanner is a hand-held or stationary input device used to read and capture information contained in a barcode. The components of a barcode scanner include a scanner, a decoder, which may be either built in or external, and a cable used to connect the reader with a computer. On the market, basically five different types of barcode readers are available and each comes with its unique and distinguished advantages. For best scanner prices online, you can browse various websites. You can also use barcode wireless scanners that come with advanced technology.


The various types of scanners include Pen Wand, Slot, Charged-Couple Device (CCD) Scanners, Image scanners and Laser scanners. Let's have a look at the different types of scanners.

Pen Wand: It's a simple barcode reader which is popular for its low cost operating system and durability. It does not contain any moving parts. It just needs to be in direct contact with the barcodes at a certain angle.


Slot scanner: It remains stationary and the item with the barcode on it is pulled manually through the slot. Slot scanners are typically used to scan barcodes on identification cards.


CCD scanner: It is often used in retail sales and has a better read-range than the Pen Wand. But it comes with a disadvantage that it cannot read a barcode that is wider than its input face.


Image scanner: It’s also called a camera reader, that uses a small video camera to capture the image of the barcode and then to decode the barcode, uses sophisticated digital image processing techniques.


Laser scanner: A laser scanner, which can be stationary or hand-held, does not need to be close to the barcodes in order to accomplish its job. It can easily read a barcode upto 24 inches away.


Barcodes scanning systems provide an array of benefits including increased operational efficiency, better customer service, and improved visibility of key business information. The new technology has offered multiple scanner softwares and you can choose according to your requirements.
