Various Types of Barcode Scanners

Virtually every industry or organization uses barcode technology today regardless of its size. Barcodes may look like an easy combination of strips and spaces, but they are the key to vital product information. To decode these barcodes, special devices like scanners are used. Barcode scanners are photosensors which see the barcodes and convert them right into a readable text that is displayed and stored on a computer or laptop. This appears to become a very long process but it really takes few milliseconds.

Barcode scanners are probably the most widely used tools today. They’re being utilized in different industries including manufacturing, warehousing, education, healthcare, and field service. The high utility aspect and the popularity of the scanners have led to the introduction of numerous varieties.

Different varieties

Barcode scanner varieties are distinguished by their form factor and their scanning technologies. The key difference in form factors is the quantity of operator manipulation required. There are wand or pen-style scanners, fixed-mount scanners, and handheld scanners. Handheld scanners vary the absolute most in available scanning technology. There are laser scanners, CCD scanners, which are also known as linear imagers, 2D scanners, also known as 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 certanly be swiped over the barcode at a constant rate of speed and at a particular angle. This makes them the smallest amount of efficient scanner to utilize, but they are the smallest amount of expensive. They’re also small, extremely durable, and not limited by the width of the barcode.

Fixed-Mount Barcode Scanners

These scanners read barcodes as they are passed in front of the scanner. They’re widely utilized in work-in-progress applications and for high-speed sorting along conveyor systems. Smaller models are barcode scanners commonly utilized in laboratory, security identification, and kiosk applications. Many of these have a laser scan engine, so they have to be mounted at a specific angle and distance from the barcodes that will pass in front of them. Unlike others, these types of are usually integrated with other equipment and automation systems.

Linear Imager Barcode Scanners

These are also referred to 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 scanners stronger than laser 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 scanners are the most used 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. These are also for sale in several variations to generally meet the requirements of special applications, such as for instance long range or high density scanning.

Omnidirectional Barcode Scanners

Unlike handheld linear scanners that really must be set up perpendicular to the barcode, omnidirectional barcode scanners can read a barcode irrespective of how it is orientated. Therefore, they speed up the scanning process and reduce user fatigue. Omnidirectional scanners are usually utilized in retail environments and can be found in on-counter and in-counter models. On-counter models are great for applications with limited counter space, such as for instance convenience stores. In-counter models are ideal in high-volume applications, such as for instance grocery stores.

2D Barcode Scanners

2D barcode scanners can capture 2D barcodes along with 1D, or linear, barcodes. They’re gaining popularity for their versatility and the future-proofing they offer being an investment. These scanners use a variety of camera technology and software to recapture barcodes. They read barcodes omnidirectionally, and 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 products on the market, always ensure that you purchase the best scanner for the application. Several types of scanners fit different working environments. Pick the barcode scanner based on your needs and industry.
