Know About Different Kinds of Barcode Scanning Technologies

Using barcode technologies in companies is beneficial in numerous methods. It improves operational efficiency, reduces mistakes, saves time, and enhances information entry. Various firms, irrespective of their size, use barcodes for their company purposes.

Barcode scanners are important tools which ease company processes in manufacturing, education, healthcare, warehousing and numerous other fields. Right here is a description of barcode scanners that use various technologies.

What is a barcode?

A barcode is an optical machine-readable data that contains a series of black bars and white spaces of varied widths. The primary intention of utilizing a barcode is to quickly and accurately entry information via the code by an automated system. The devices that read data present on barcodes are called barcode scanners.

How does a barcode scanner function?

A barcode scanner consists of an illumination source, sensor, and decoder. An illumination source is used to illuminate the bars and spaces on the barcode. The black bars absorb light from the source and white spaces reflect it. The sensor detects the mirrored light from the barcode and generates a signal of varied voltage that represents the intensity of reflection. A decoder with specific software program decodes the signal into a readable text that is shown on the monitor. Data collected in this way is stored and managed by specific databases. Allow us look at barcode scanners and their various scanning technologies.

Different types of scanning technologies

Barcode scanners use various scanning technologies such as laser and imaging technologies. The following are numerous types of barcode scanners.

Pen-type scanners

They are also called as wand scanners and are appropriate for reduced-quantity and desktop programs. They contain a photodiode that is positioned next to a light source. When the scanner is swiped across the barcode in a steady motion, the photodiode measures the intensity of the mirrored light. Because they are manually swiped, wand scanners are not restricted by the width of the barcode. One needs to ensure that they are swiped at constant price of speed at a specific angle. Pen-type scanners are inexpensive, small, and extremely tough.

Laser barcode scanners

A laser beam is used as a light source for capturing barcode information. They contain an oscillating mirror or a rotating prism which moves the laser beam back and forth across the barcode. Laser barcode scanners are extremely exact and accurate. They can read barcodes from greater distances also. They are used mainly in locations exactly where barcodes require bright light for reading. They are appropriate for programs requiring lengthy range or higher density scanning.

Omni-directional barcode scanners

The title itself suggests that these scanners can read barcodes in any path. They mainly use laser beams as a light source. A set of fixed mirrors and a rotating mirror present in omni-directional barcode scanners create patterns of laser beams. Like laser scanners, they can also read data from greater distances. They have higher efficiency and therefore can even read badly printed, torn, or wrinkled barcodes.

As they read barcodes on products irrespective of their orientation, they enhance the speed of scanning procedure. They are perfect for reading barcodes a couple of inches absent for retail purposes and also for reading distant barcodes like these on industrial conveyors.

CCD scanners

CCD (Charged Coupled Gadget) scanners, also called as linear picture scanners, measure the intensity of light by a series of small light sensors. Hundreds of sensors organized in a row develop a voltage pattern that is identical to the pattern in the barcode. CCD scanners measure the emitted ambient light and therefore are various from laser scanners. They are appropriate for programs in retail, distribution, stock and shipping. As they do not have any moving parts like rotating mirrors, they are much more tough than laser scanners.

2D scanners

2D scanners use a small digital camera for capturing an picture of the barcode. Superior digital picture processing methods are used to decode the barcode from the picture. The benefit of utilizing 2D scanners is that they can read barcodes moving at quicker prices and can be used for industrial conveyor scanning. They can read 1D or 2D barcodes omni-directionally and some can also capture images of damaged packages or signatures.

Choose the barcode scanner primarily based on the type of software, type of barcode, and the environment in which you use it. Keep in mind, choice of a right scanner helps you in improving the efficiency of your company.
