dr martens 1461z Free Articles Online Different Varieties of Barcode Scanners
Almost every industry or organization uses barcode technology today irrespective of its size. Barcodes may look like a simple combination of strips and spaces, but they are the key to vital product information. To decode these barcodes, special devices like barcode scanners are used. Barcode scanners are photosensors which read the barcodes and convert them into a readable text that is displayed and stored on a computer or laptop. This appears to be a very long process but it just takes few milliseconds.
Barcode scanners are probably the most widely used tools today. They are being used in different industries including manufacturing, warehousing, education, healthcare, and field service. The high utility aspect and the popularity of the barcode scanners have resulted in the introduction of many varieties of barcode scanners.
Barcode scanner varieties are distinguished by their form factor and their scanning technologies. The main difference in form factors is the amount of operator manipulation required. There are wand or pen style scanners, fixed mount scanners, and handheld scanners. Handheld barcode scanners vary the most in available scanning technology. There are laser scanners, CCD scanners, which are also called linear imagers, 2D scanners, also called area imagers, and omnidirectional scanners. The scanning technology should be chosen based on the application and requirements.
Wand or pen style barcode readers must be swiped over the barcode at a consistent rate of speed and at a particular angle. This makes them the least efficient scanner to use, but they are the least expensive. They are also small, extremely durable, and not limited by the width of the barcode.
Fixed mount barcode scanners read barcodes as they are passed in front of the scanner. They are widely used in work in progress applications and for high speed sorting along conveyor systems. Smaller models are commonly used in laboratory, security identification, and kiosk applications. Most fixed mount barcode scanners have a laser scan engine, so they must be mounted at a specific angle and distance from the barcodes that will pass in front of them. Unlike other barcode scanners, most fixed mount barcode scanners are typically integrated with other equipment and automation systems.
Linear Imager Barcode Scanners
Linear imager barcode scanners are also known as CCD scanners, CCD LR (long range) scanners, and full array imagers. The scanning technology they employ uses no moving parts, thus making the linear imager barcode scanners more durable than laser barcode scanners, but they do have a shorter reading distance of contact to two feet. Linear imagers are ideal for reading damaged or poorly printed barcodes and for reading barcodes under plastic film or covering.
Laser barcode scanners are the most popular scanning technology in the industry. The brightness and sharpness of laser scanners offer greater preciseness and visibility when targeting a barcode, especially in bright light. Therefore, they speed up the scanning process and reduce user fatigue. Omnidirectional scanners are typically used in retail environments and are available in on counter and in counter models. On counter models are good for applications with limited counter space, such as convenience stores. In counter models are ideal in high volume applications, such as grocery stores.
2D barcode scanners can capture 2D barcodes as well as 1D, or linear, barcodes. They are gaining popularity because of their versatility and the future proofing they offer as an investment. 2D barcode scanners use a combination of digital camera technology and software to capture barcodes. They read barcodes omnidirectionally, so the barcodes can be orientated in any direction. Some models can also capture digital images and signatures.
With such a wide variety of barcode scanners in the market, always make sure that you buy the right barcode scanner for your application.
