Advantages of 2D & Laser Barcode Scanners

A barcode scanner is an electronic device used to quickly and accurately capture product data from the barcodes at the check out counter of most shops and stores. The working principle of both 2D & Laser Barcode Scanners is the same. They contain decoder circuitry which analyzes the barcode's image data that is provided by the sensor and sends the barcode's content back to the scanner's output port.

Laser barcode scanners are more easy to use as they do not need to be in direct contact with a barcode in order to read it. A standard laser scanner will be able to read a barcode from approximately 6 to 24 inches away. Both 2D & Laser Barcode Scanners which are handheld can be easily bought for around 150$. Not only are these devices fast and accurate but can also give outstanding performances even in the harshest environments.

Most industries including retail establishments, healthcare, laboratories, libraries etc use barcode scanners. They are also used for document management, tracking parcels and mail and even for issuing tickets. These scanners offer immense preciseness and visibility as they can read a barcode at any angle. Laser barcode scanners are capable of reading longer and high density barcodes much clearly than the less expensive LED or CCD scanners and their scanning distance is greater as well. Both 2D & Laser Barcode Scanners are easy to install and easy to use.

The features of the barcode scanner are designed to increase work efficiency and minimize errors during operation. As these features are proportional to cost, so you need to carefully think about your budget while purchasing a barcode scanner.

While purchasing barcode scanners there are certain features that you must take under consideration. Motion tolerance is a fair standard for judging and comparing barcode scanners. Motion tolerance basically means that you can scan a number of barcodes together without releasing the trigger that initiates the barcode scan. . This allows you to scan items that are closely packed together quickly with minimal user intervention. This decreases queue time of checkout counters in shops and stores and subsequently results in a better customer relationship.

While purchasing 2D & Laser Barcode Scanners you should not overlook the scanner's resistance to physical abuse. In everyday use scanners are often dropped and they should have the ability to withstand the shock. Nowadays many barcode manufacturers are implementing single circuit board designs which minimize the chances of dislodging internal parts during a drop.

Last but not the least, barcode scanners should be able to read damaged barcodes. Since laser barcode scanners scan from one end to another, they ignore a break in the barcode and resumes interpreting the information as soon as the barcode becomes readable again. Without the ability to scan damaged barcodes the data in the barcode would have to be interpreted manually taking a really long time. When a barcode scanner fulfils all the above criteria successfully then you can be assured that you are buying a quality scanner.

Motorola Symbol LS2280, Wasp WLS9500 Series, Honeywell 4820 etc are some of the high quality barcode scanners which are available in the market today.
