Barcode scanners are electronic devices that reads unique codes imprinted on a special sticker. It basically is composed of a light source, light sensors and lens. The light sensor translates the visual impulses to the electrical ones. The motor has a decoder circuitry that analyzes the image data in case,granted from the sensor. Data will then be sent to the scanner's production port.
Each industrial item is given a unique code. It could be a combination of letters, numbers and/or other characters. This is then imprinted on special stickers or labels which the barcode scanner could read.
There are many types of barcode scanners ready in the market today. It differs from how it works (method), the type of technology and the housing type. The methods of scanning are fine from the amount of manipulation that the operator has.
There is a pen type, semi-automatic handheld, fix-mount for self-operating scanning and reader gates type for self-operating scanning. The pen type scanners are used by swiping over the code to the pen. Semi-automatic handheld scanners are held very close to the label. In fix-mount scanners, the target must coincide with the scanner's imaging capability. The label will be passed over the scanner. In the reader gates for self-operating scanning, the code is under the gate for scanning purposes.
We could differentiate the three in supplementary detail. The pen type scanners have light source and photodiode. In this type, there is a steady move of the tip of the pen to the bars. This is done in steady motion. The laser type functions the same as the pen type. The only incompatibility is that the first one works with a laser beam.
Ccd readers are often referred as Led scanners. This scanner uses light sensors. Camera Based Readers use 2D imaging. This uses small video camera to be able to capture the bar code image. Omni Directional Scanning use pattern of beams so the scanner can read barcodes.
The housing types of barcodes contain handheld scanner, Pen Scanner, Stationary Scanner, Fixed position scanner, Pda Scanner and self-operating Reader.
The major role or use of barcode scanner is to capture the data in the printed material. The data is then transmitted to the computer ideas to translate this facts and save it to a database. All scanners are compatible with distinct computers.
The wireless barcode scanner was recently introduced. This is the most contemporary innovation so far. It is more expensive since it is a fairly new product, yet very conveyable and handy to many businesses. It makes it easier to use without cords. It can be taken anywhere without limitations.
Stockrooms are commonly very big and the ceilings are very high. The employees could legitimately bring this motor with them without having to drag a long uncoiled wire, or without reasoning of where the nearest power outlet is.
There are also two types of wireless barcode scanners: the cordless and the Bluetooth. The cordless barcode scanners are just like the cordless phones. They function even without a wire. The Bluetooth barcode scanner is a distinct one. This type of scanner works by receiving frequencies on air. It could legitimately replacement data also in computers or any gismo with Bluetooth Usb ports.
Wireless or traditional, these barcode scanners have revolutionized the operation ideas of many businesses. It made dealings, narrative keepings, inventories and sales more reliant and effective. It also greatly reduced cases of pilferage, theft or stealing.
