Know About the Difference between Linear (1D) and 2D Barcodes

0
0

Barcodes have helped businesses streamline their business processes, improve workforce productivity, and achieve greater operational efficiency. Barcodes have been successfully integrated in business processes across various industries to increase their effectiveness, speed, and accuracy for better a customer experience. Barcodes are mainly categorized into two types: Linear or 1D barcodes and 2D barcodes. Each barcode type is selected as per relevant business requirements to fulfill the end objective. A barcode system consists of a scanner, a barcode label, a printer, and an external database.

Linear Barcodes:
Linear or 1D barcodes consists of parallel black bars and white spaces that can represent any form of data. UPC, Code 128, and Code 39 are some of the common 1D symbologies presently used.

Stores data only in horizontal direction
The bars and spaces in linear barcodes are grouped together to represent a specific ASCII character or a numeric digit. As the linear barcodes contains only vertical bars and spaces, the data can be stored only in horizontal direction. Even while reading the data from linear barcodes only the width of the bars and spaces is considered. Thus, linear barcodes are also referred as one-dimensional barcodes.

Stores much less data
Linear or 1D barcodes store a smaller amount of data, usually up to 12 or 20 digits. The linear or 1D barcodes contain information, which when scanned is matched with relevant data stored in local or central database leading to retrieval of a large amount of information about the item scanned.

Cannot retrieve data when erased or damaged
One of the drawbacks of linear barcodes is that it is difficult to retrieve stored data when the barcode label is damaged or poorly printed. Addition of a single extra line at the start or end of barcode can impair the readability of the linear barcode. A small tear or drawing a line through the barcode parallel to bars can disturb the decoding algorithm that makes it difficult to retrieve or read data.

2D Barcodes:
Two-dimensional barcodes have more data representation capability and can contain more detailed information. 2D barcodes can be in a matrix or stacked format. Stacked-barcodes are like a set of linear barcodes literally stacked on top of each other. PDF417 is the best example of a stacked barcode. Matrix codes are made up of a pattern of cells that can be square, hexagonal, or circular in shape and are similar in appearance to checkerboards. Data Matrix and MaxiCode are two commonly used matrix barcodes.

Store data in horizontal and vertical direction
Two-dimensional barcodes have larger data storage capacity as the data is stored in both horizontal and vertical directions of the barcode. In contrast to the 12-20 characters that a typical linear barcode can store, 2D symbologies are able to encode up to several thousand characters of machine readable data.

Stores large data
The amount of data that can be stored in 2D barcodes can reach up to thousands of alphanumeric data. The 2D barcodes ensure faster data processing as it can act as a database itself storing all the necessary data. They can condense the information from numerous linear barcodes into a single 2D barcode thus saving considerable space. The need to have external database is eliminated as accurate information can be received from the product itself. By providing immediate access to large stored data, 2D barcodes can make business process faster, accurate, less costly, and reliable.

Easy to retrieve data when erased or damaged
Unlike 1D barcodes, 2D barcodes can have error correction formulas built into the symbol which allow data to be retrieved even if the barcode is damaged. In fact, a significant portion of the surface area can be damaged and the information will still be intact. For example, some 2D symbols can lose up to a third of its surface and still be decoded. The Error Correction Code (ECC) has ability to rebuild the data from sections of barcode that has been damaged and deliver consistent correct information. Also, 2D barcodes printed on hard surfaces exposed to rugged or harsh conditions can be easily read by 2D barcode scanners.

Both 1D and 2D barcodes ensure functional enhancement of business process, efficient automated data collection, and processing of large amounts of data with accuracy across any industry. There are a number of factors to consider, like symbology compliance to industry specific standards, amount and type of data to be encoded, etc., before deciding on which type of symbology to use.

Barcode readers ensure better functioning of business processes with efficient and accurate automatic identification of products. Various barcode technologies have evolved that help in tracking inventory tracking, monitoring stock movement, increasing operational efficiency, improving employee productivity, etc. Various types of barcode technologies are used effectively across various sectors like healthcare, hospitality, retail, manufacturing, distribution, warehousing, etc.

Barcode Reader Technologies:
Deciding on which barcode reader technology depends upon the type of barcode that will be scanned, the environment in which it will be used, and the connection type required (i.e. USB, serial, or keyboard).

Pen-Style Readers
Pen-style barcode readers, also called wand barcode readers, consist of a light source and a photodiode placed next to each other at the tip of the pen. As the pen is swiped across the barcode, the photodiode measures the intensity of light reflected from the surface. A waveform is generated that represents the exact widths of bars and spaces in the barcode. The dark color of bars absorbs light while the white spaces reflect light, thereby making a specific pattern of waveform. This voltage waveform is then converted by the pen-type reader to retrieve product information quickly. Because wand readers are manually swiped across the barcode, they are not limited by the width of the barcode. They do require the user to pass the wand over the barcode at a consistent rate of speed and at a particular angle. The pen-type readers are not the most efficient scanners, but they are small, extremely durable, and economical. Pen-style barcode readers are suited for low-volume and desktop applications.

Laser Scanners
Laser barcode scanners offer more precise readability of barcodes as a laser beam is employed instead of a light source. An oscillating mirror or a rotating prism is used to move the laser beam back and forth across the barcode. The brightness and sharpness of laser beam ensures preciseness and greater accuracy in reading barcodes. Laser scanners can read the barcodes from greater distances and are ideal for applications where barcodes need to be read in bright light.

CCD Readers
CCD (Charged Coupled Device) readers, also called linear imager barcode scanners, consist of a series of tiny light sensors that measure the intensity of light that is right in front of them. Linear imagers can effectively read barcodes from a few inches to several feet away. They are more robust and are designed to withstand harsh working conditions. Linear imagers are suited for use in various sectors like retail, distribution, shipping, receiving, and inventory.

Camera Based Readers
The latest in the barcode reader technology is the camera-based barcode readers or 2D imaging scanners. They utilize a small camera to take an image of the barcode and then process this image using advanced digital image processing techniques to decode the barcode. This reader forms an image using sensors arranged in hundreds of rows. 2D barcode scanners can even retrieve information from barcode labels that they are wrinkled or damaged. These scanners have capability to read barcodes moving at faster rates like cartons on a conveyor belt. 2D Barcode Scanners read barcodes omnidirectionally, so the barcodes can be orientated in any direction. Some 2D barcode scanners can also capture digital images and signatures.

Omnidirectional Barcode Scanners
Omnidirectional barcode scanners disperse laser beams in every direction making it possible to read the barcode from every possible angle. A rotating mirror and a set of fixed mirrors are used in omnidirectional barcode scanners to generate the pattern of laser beams. These scanners have higher barcode scanning capability with scan ranges varying between few inches to several feet. Omnidirectional barcode scanners can be put to use in retail environments where barcodes have to be read at a distance of few inches or in industries where barcodes have be read from a distance of few feet in harsh conditions. It can also read barcodes if they are torn, wrinkled, or damaged.

Cell Phone Cameras
Barcode scanning apps are now available for certain cell phones with cameras. Some 2D barcodes like QR and Data Matrix codes are optimized for scanning by cell phones. Although this technology is still in its nascent stage, it opens a wide range of opportunities for possible applications. At present, iPhone and a few phones using the Google Android platform have barcode scanning apps available for use. Most of these apps are designed as shopping tools. They use the barcode number to search a number of web sites, like Amazon and Google, to pull up product information, price comparisons, and customer reviews. Some will even utilize the GPS in the phone to locate the nearest store that has the item in stock. Cell phone barcode scanning can be put to various other uses like giving access to valid ticket holders at venues, personal finance, inventory reporting, asset tracking, shopping etc.

The barcode reader technology should be selected based on each business’ specific application. The barcode reader should be fast, easy to use, and durable enough to withstand the working conditions, whether it be in an office, retail store, factory, warehouse, or outside in a work yard or vehicle.

In today’s competitive business environment, staying ahead using latest technologies is critical to your success. Barcode technology is an effective way to meet the competitive challenges faced by your organization. Today, almost all kinds of businesses across the globe are implementing this technology and are quite successful. To use a barcodes, it must be printed first, which has increased the demand for barcode printers. The success of any business using barcode technology depends on the efficiency of the labeling technology it uses.

A barcode’s readability, or scannability, depends on its print quality. There are four different types of print technologies available to print barcodes. They are Dot Matrix, Inkjet, Laser and Thermal printers.

There are several parameters that are to be measured before choosing a printer such as the quality of printing, cost of the initial installation, long term maintenance costs and the percentage of the material wasted. When you take a look at all these parameters, thermal barcode printers are the most efficient and widely used ones.

Dot matrix printers create poor quality barcodes that can be difficult to scan. Dot matrix printers are also limited in print speed and size. They tend to be slow in printing and cannot print small barcodes.

Laser and inkjet printers have great print quality, but they must print the barcode as an image, which uses more memory and slows down the print speed. Laser and inkjet printers must print an entire sheet of labels, instead of one at a time. They also have a very limited array of label facestocks on which they can print.

Thermal barcode printers can print high quality text and graphics as well as barcodes. The barcode fonts reside in the thermal printer, so it will not slow down the print speed, which can get up to 12 inches per second. Thermal printers can print any amount of labels from one at a time up to an entire roll. They can also print very small, high density barcodes and can print on a wide variety of label sizes and facestocks.

Types of Thermal Printing Methods
Thermal barcode printers use two different printing methods: direct thermal and thermal transfer. Most printers can do both so it all comes down to selecting the correct media for the application.

Direct Thermal
Direct thermal printers do not use ink, toner or ribbon; they create images directly on treated labels or tags. Direct thermal printers use chemically treated, heat-sensitive barcode label that blackens when it passes under the thermal printhead of the printer.

Simple design of thermal printers makes them durable and easy to use. Direct thermal printers are simple and inexpensive to maintain compared to other types of printers such as inkjet, laser, impact and thermal transfer as there is no ink, toner or ribbon to monitor or replace.

Direct thermal labels are sensitive to heat, sunlight and abrasion. They also have a shorter life than thermal transfer labels. Therefore, they are recommended for temporary, indoor, general purpose barcode labeling.

Thermal transfer printers
Thermal transfer printers use a ribbon and a printhead to produce accurate, high-quality barcode images. In this method of printing, the thermal printhead uses heat to transfer ink from the ribbon to the label or tag material to form the images. This technique provides images with high quality and durability.

Thermal transfer printers can print barcode images on a wider variety of media including paper, polyester and other synthetic label materials. Thermal transfer printers produce the toughest and longest-lasting barcode labels that can resist abrasion and chemicals. In addition to common labels and tags, they can create extremely durable asset tags, wristbands, certification labels, etc. for use indoors and outdoors.

Types of Thermal Barcode Printers
Thermal barcode printers come in a variety of form factors: desktop, mid-range, industrial, and portable. One of the biggest factors to determine which barcode printer to select is the number of labels that are going to be printed daily.

Desktop Barcode Printers
Desktop barcode printers are ideal for applications where space and budget are limited. They have a compact design that fits neatly on a desk, countertop, or POS station. Desktop barcode printers are recommended when printing less than 100 paper labels per day.

Desktop barcode printers work best with paper labels and tags which are larger than 1.5″ x 0.5″. They are also the perfect choice for printing vinyl jewelry labels. A desktop barcode printer can print on other synthetic materials, but in limited quantities.

Mid-Range Barcode Printers
Mid-range, or light industrial, barcode printers can handle a wide variety of media sizes, from very small serial barcode labels on cell phone components to very large chemical drum barcode labels. They can also handle a wide variety of media types, from basic paper barcode labels to synthetic barcode labels that are flexible enough to wrap around a vial or durable enough to withstand extreme weather conditions outdoors.

Mid-range barcode printers are designed to print about a 1000 paper or synthetic labels a day. With faster processors and built-in memory, light industrial barcode printers are able to handle more complex barcode label designs quicker than a desktop barcode printer. Light industrial barcode printers may not be suitable for the most demanding barcode printing environments.

Industrial Barcode Printers
Industrial barcode printers are often used in large warehouses and manufacturing facilities to create hundreds and thousands of labels, where reliability and durability are critical. These printers are designed to print paper or synthetic labels 24 x 7.

Industrial barcode printers can print a wider range of label sizes, from very large to very small. They also have higher resolution print heads for printing detailed graphics or tiny barcodes and fonts. They are constructed to work in tougher environments beyond regular offices.

Portable Barcode Printers
Portable barcode printers are intended for the worker on the go or out in the field and are often used for quick labeling purposes. Portable barcode printers can increase efficiency and worker productivity by helping you print barcode labels on demand wherever they are needed. Portable barcode printers can be used virtually anywhere and relocated in minutes as they are free from cabling and a wired network infrastructure.

Portable barcode printers will communicate through radio frequency or Bluetooth technology, in addition to offering standard cable connectivity. Print widths range between 2 and 4 inches. They can print barcode labels on assembly lines, shipping and receiving docks, patient bedsides, retail checkouts, offices and anywhere the information is needed.

The type of barcode printer used by different businesses is dependent on each business’ application needs. Each and every type of barcode printer has specific advantages. So, you should assess your barcode printing requirements before you make any purchasing decision.

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.

Different varieties
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 Barcode Scanners
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
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
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. Laser barcode scanners are also available in several variations to meet the needs of special applications, such as long range or high density scanning.

Omnidirectional Barcode Scanners
Unlike handheld linear barcode scanners that must be lined up perpendicular to the barcode, omnidirectional barcode scanners can read a barcode no matter how it is orientated. 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
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. Different types of barcode scanners fit different working environments. Choose the barcode scanner based on your requirements and industry.

Fair Exchange is no robbery, or is it…

Why bother with professional in-house email systems? It’s a very good question. Why on earth would anyone want to invest in an expensive, dedicated server, load up a proprietary business email package like MS Exchange, Lotus Notes or similar, pay a man (or a woman) to set it up and then train everyone on how to use it? Oh, and look after it every day thereafter too. There are many companies out there that do it every week and think no more about it. It is worth having a think about the initial and ongoing costs of such an investment.

Analysis reveals that it’s actually quite hard to justify such a big investment, particularly for a small to medium sized company, not to mention all the patching, software updates and daily maintenance required for an in-house mail beast. And yes, the Email server really can be a monster, causing problems and headaches for anyone with the responsibility of looking after it; feeding in the patches and updates and anti-spam and anti virus solutions that are essential fodder for modern mail systems. Then, of course, there’s the black day when all the data disappears. The mail server goes down and everyone in the company is immediately on your back demanding that their mailboxes are reinstated now! Their individual need is always the most urgent (everyone says the same thing) and the mail that’s been lost is simply vital for a major contract or a critical business deal. Yes, there’s always the back-up, just so long as you remembered to back-up. Then there’s the question of who to blame for the loss of business and managementt ime and …OK, you get the picture. I’ll shut up now. It’s probably causing you a headache just thinking about the series of horrible catastrophes and aftershocks that would materialise if your in-house mail server died unexpectedly, and worse still, you lost all the information.

Admittedly there’s nothing intrinsically wrong with the technology of mail servers, and certainly the latest mail packages do everything that companies would ever need – often far more than you would expect. The real issue is the management and the support of the server and the software. If your company is a 24/7/365 company with people requiring access to their mail from the office and from home, as well as remote use on handheld devices, it stands to reason that you will need to buy in suitable, talented, experienced, 24-hour support and maintenance, which, of course, for the 24-hour company means three people! Ouch. That’s a big cost you perhaps did not expect on top of the server and the multiple software licenses.

You will doubtless argue that you have full control with an in-house system, and of course you would be right. For a very large corporation with massive IT resource, it probably makes sense to look at the option of an in-house system, particularly if you are already paying for that professional IT expertise. However, for a smaller company, the luxury of absolute control can end up costing you a lot more than you bargained for, and bringing with it levels of responsibility and headaches for which you really have no extra time.

So, what’s the alternative? Do away with email altogether and return to the quill? I hardly think so. Email is here to stay and will continue to develop in many forms. And it is in the development of online managed Exchange services where the huge advances have been made in both efficiency and cost.

Professional hosting companies such as Rackspace Limited are now offering fully featured email hosting.

packages based on banks of dedicated servers operating in climate-controlled, highly secure data centres, which are manned by level three professional support staff, providing 24-hour support 365 days of the year. They work with managed mail systems 24 hours a day and know them inside out. Accordingly, any possible problems are rapidly identified before they materialise in failure and are often solved even before you know are aware of them.

As a customer of an email hosting solution provider like Rackspace all you need to worry about is the initial set up of your mail accounts and the size of the individual mailboxes. Thereafter everything involved in the operation, maintenance, software updates, server patching, anti-virus, prevention of DOS attacks, and backup of all your mail and attachments becomes a part of the overall package.

As a professional business user I am sure you can begin to see the benefits unfolding. All that hardware and maintenance responsibility is wholly down to the company providing the email hosting service. They are also responsible for the day to day operation and to ensure that your service is up and running 24/7/365. And, yes, thank the heavens; it’s down to them if it goes down! The great thing is that being consummate professionals and living ‘email hosting’ every hour of every day, they will probably have the package up and running in an hour even if the server has died! And all your mail will have been restored from the permanent back-up.

Yes, of course it costs money, but if you want one of the world’s most secure email hosting solutions, accessible from wherever you are in the world with full mobile compatibility (Iphone, Blackberry and the like), and no fear of losing any valuable data, contacts or messages, then you have to go out on a very long limb if you opt to try and justify to retain an in-house solution. The advent of cloud hosting has made lower cost email hosting packages totally accessible to the majority of business users, even much smaller companies. Not every company wants all the functions associated with Microsoft Exchange – shared calendars, out of office etc. And companies like Rackspace are now offering businesses viable, cost-reduced, fully managed email hosting packages that provide all the care and attention necessary for full reliability and availability, but without the non-essential frills.

Comparisons are available online to help you choose the most appropriate email hosting solution for your company, and I’m willing to bet that when you have all the facts at your fingertips and you compare the real costs with those of a comparable in-house solution you will say thanks very much for this article, it saved me a fortune.

Object-Oriented Concepts and Constructs

0
0

Class, object, method, message, instance variable, and inheritance are the basic concepts of the OO technology. OO metrics are mainly measures of how these constructs are used in the design and development process. Therefore, a short review of definitions is in order.

– A class is a template from which objects can be created. It defines the structure and capabilities of an object instance. The class definition includes the state data and the behaviors (methods) for the instances of that class. The class can be thought of as a factory that creates instances as needed. For example, an Account class may have methods to allow deposits and withdrawals, using a balance instance variable to hold the current balance. This definition defines how an Account works, but it is not an actual account.

– An abstract class is a class that has no instances, created to facilitate sharing of state data and services among similar, more specialized subclasses.

– A concrete class is a class that has instances. For example, there might be a Savings Account class with a number of instances in a bank application.

– An object is an instantiation of a class. It is anything that models things in the real world. These things can be physical entities such as cars, or events such as a concert, or abstractions such as a general-purpose account. An object has state (data) and behavior (methods or services), as defined for the class of objects it belongs to.

– A method is a class service behavior. It operates on data in response to a message and is defined as part of the declaration of a class. Methods reflect how a problem is broken into segments and the capabilities other classes expect of a given class.

– Message: Objects communicate via messages. To request a service from another object, an object sends it a message. This is the only means to get information from an object, because its data is not directly accessible (this is called encapsulation).

– Instance variable is a place to store and refer to an object’s state data. In traditional programming, this would be a data variable. In OO paradigm, data is made up of instance variables of an object.

– Inheritance: Similar classes of objects can be organized into categories called class hierarchies. The lower-level classes (called subclasses) can use the services of all the higher classes in their hierarchy. This is called inheritance. Inheritance is simply a way of reusing services and data. As an example, Savings accounts are types of general Account, and IRA accounts are types of Savings accounts. The Savings account inherits the capability to handle deposits from the Account class. The number of subclasses in the class hierarchy is called hierarchy nesting or depth of inheritance tree (DIT).

Due to rapid growth in science and technology, there is increased usage of gadgets which has enhanced our comfort levels. One of the biggest and valuable innovation in science and technology is invention of barcode scanners. In general, barcode scanners are used to crack information present in the barcodes and to convert it into a readable format in a quick, effective and accurate manner. They have a huge positive impact on both the industrial and commercial sectors. Barcode scanners have reduced the time and effort required in the process of billing in the commercial segment and are vital in increasing operating efficiency and the productivity in the industrial sector.

The most popular barcode scanners utilize laser barcode scanning technology. A laser barcode scanner is 50 times faster and 10,000 times more accurate when compared to manual data entry. They use a laser beam instead of a light source to capture information in the barcodes. So, they have increased data retrieval and processing speed. A laser barcode scanner can perform up to 500 scans per second. Laser barcode scanners are more convenient to use as they come in both handheld and fixed mount configurations.

1. Types in terms of read range
A laser barcode scanner need not be in contact or very close to the barcode to retrieve information. Depending on the model, they can read a barcode which is several feet away. They can be classified based on their read range into three types. There are standard barcode scanners, long-range barcode scanners and extra long-range barcode scanners.

Standard barcode scanners
Standard-range laser barcode scanners scan barcodes which are fairly close. A barcode that is 6 to 24 inches away can be read by a standard-range laser barcode scanner. They are generally used in department stores or retail outlets as point of sale equipment to perform mass scanning.

Long-range barcode scanners
Long-range laser barcode scanners are used to scan barcodes which are placed at long distances. A long-range laser barcode scanner can read a barcode that is 2 to 8 feet away from the scanner. They can read barcodes at varying distances. They are mainly used in small warehouses, manufacturing plants, etc.

Extra long-range barcode scanners
Extra long-range laser barcode scanners are very efficient barcode scanners. They can even scan barcodes which are placed at a distance of 30 feet. They are highly durable and can withstand harsh environments in warehouses. This type of extra long-range laser barcode scanners are ideal for work-in-process, in transit visibility applications, and warehouse management.

2. Other benefits
Generally, barcode scanners can read barcodes which are just few inches away. As mentioned above, today’s several kinds of laser scanners can read barcodes which are at longer distances. It is one of the main reasons why more and more people are using laser barcode scanners. Apart from this, there are many other reasons why people choose laser barcode scanners such as:

Reads better than other type of scanners
Laser barcode scanners are highly efficient when compared to other type of scanners. They produce bright and sharp laser beams to ensure preciseness and greater accuracy in reading barcodes. Laser scanners can read barcodes even in bright light.

Long range or high density scanning
The major advantage of laser barcode scanners is that they can read barcodes which are placed several feet away. Because of more powerful light emission, they can be used to read even a barcode which is 30 feet away. They offer high density scanning which helps in scanning even very small barcodes on electronic components accurately.

Most helpful in the industries
Laser barcode scanners are very helpful in the industries because of their ability to withstand harsh environments. They can scan many barcodes within few milliseconds. Laser barcode scanners are used almost in all industries including manufacturing, healthcare, retailing, libraries, warehouses, education, cargo and shipping businesses.

There are numerous benefits of laser barcode scanners as mentioned above. You should be aware of their types and benefits to choose a right one for your business. The right barcode scanner is essential for better inventory management and customer service.
