Tips to Choose the Right Barcode Scanner

Modern point of sale (POS) systems require robust hardware components to function seamlessly including a point of sale (POS) terminals, monitors, barcode scanners, cash drawers, payment processors, and receipt printers. These devices need to be compatible with each other and can be integrated with the point of sale (POS) software you use. Barcodes and barcode scanners are an integral component of modern-day point of sale (POS) systems that help perform multiple business operations like tracking and managing inventory which helps minimise manual efforts, saving overall time.

The exponential use of barcodes over the past several years is no secret. Different businesses implement barcode technologies to meet their business&#;s unique needs. Although barcodes were initially used by larger businesses that have a large volume of products in their inventory, nowadays, businesses of all sizes use barcodes. Almost every commodity in today&#;s world comes with a barcode label attached that contains product-related information encoded within it. To read and decode these barcodes, a robust device known as a barcode scanner is used. Depending on their performance and portability, there are different types of barcode scanners available.

This blog discusses the different types of barcode scanners and the tips to pick the right device for your barcode scanning needs.

What are Barcodes?

Barcodes are systematically arranged patterns of lines and numbers in different widths that when put together form a scannable code. These lines and patterns are arranged in a parallel form with a single barcode representing large amounts of data regarding a certain product. With about 100 billion variations of barcodes available, barcodes can be customised as per your business needs.

Based on the concept of symbiology, barcode scanners read the symbols, identify them, and convert them to useful information such as the type of items, price, origin, and location.

What are the Types of Barcodes?

Essentially, there are two distinct types of barcodes:

• One-dimensional (1D) Barcodes: One-dimensional barcodes are the most common types of barcodes that come in vertical lines of different widths with gaps in between. These combinations of lines and gaps represent the code that the scanner will read. The barcode scanners read one-dimensional barcodes horizontally. Usually, there are 12 digits on one-dimensional (1D) barcodes, corresponding to UPC numbers. The first 6 digits of these barcodes are the identification number of the manufacturer, the next 5 digits contain product-related information, and the last digit is to verify if the rest of the code has been read correctly. One-dimensional (1D) barcodes are designed to store up to 8-25 characters of data. Adding extra bars and spaces to the barcodes to extend the information-carrying capacity of a barcode is called stacking. One-dimensional (1D) barcodes are usually smaller in size making them easily printable. Adding more information on a barcode increases its complexity.

• Two-dimensional (2D) Barcodes: Unlike one-dimensional (1D) barcodes, two-dimensional (2D) barcodes are designed to store more information. Other than simple characters, two-dimensional (2D) barcodes can contain information like images, website addresses, pricing, and more. Usually shaped in square and rectangular forms, the two-dimensional (2D) barcodes can be read both vertically and horizontally. Additionally, two-dimensional (2D) barcodes can encode data in the forms of dots, squares, hexagons, and other shapes. Although capable of storing up to characters and digits of data, these barcodes are small in size. These barcodes can be read from any angle and the slightest damage also ensures 100% readability. Unlike one-dimensional (1D) barcode scanners, two-dimensional (2D) barcode scanners can be scanned using smartphones too.

NOTE: QR codes and data matrix codes are the perfect examples of two-dimensional (2D) barcodes that can be read perfectly using a two-dimensional (2D) barcode scanner.

What are Barcode Scanners?

Often referred to as a barcode reader, barcode scanners are optical devices that are designed specifically to read and decode data encoded within a printed barcode. Once the scanner scans the data, it transmits the information from the barcode to the attached computer via the output port of the scanner. Barcode scanners comes with a light source, a light sensor, and a lens that converts optical impulses to electrical signals for computers to catch. You can integrate your barcode scanners with your computer using a USB cable. Bluetooth, or wireless networks.

What are the Types of Barcode Scanners?

There are 4 different types of barcode scanners depending on the technology used, interface, design, and capabilities.

• Pen-type Barcode Scanners: As the name suggests, these barcode scanners are shaped like a pen or a small wand, hence the name. The tip of pen-type barcode scanners come with an LED light and a photodiode. On passing the tip of the barcode scanner over a barcode, the LED light that gets emitted highlights the black and white bars of the one-dimensional (1D) barcodes. The photodiode measures the light that reflects back, indicating the size of the bars, and decoding the barcodes. The barcode scanner then transmits the captured information to the connected computer. Known for their durability, affordability, and fast barcode scanning speed, the pen-type barcode scanners yet require some practice for effective handling.

• Laser Barcode Scanners: More advanced than pen-type barcode scanners, laser scanners are the most popular type of barcode scanners. In these scanners, the laser beam is usually directed at a mirror within the scanner, When the mirror reflects the laser rays across the barcode, the light gets reflected back, showing the areas of the barcodes that are darkened. This reflection converts the decoded information and transmits the data to the connected computer. Used primarily in retail setups, the laser scanners can be used as a fixed countertop devices or used as a handheld barcode scanners. The biggest USP of the laser scanner is that they can scan barcodes from a distance of 6 to 24 inches and the long-range barcode scanners can read from a distance of 2 to 8 feet.

• CCD Scanners: Charge-coupled devices (CCD) barcode scanners are also known as LED barcode scanners and are comparatively expensive devices. These barcode scanners come with hundreds of small LED lights arranged in a single row. When all the lights are directed at the barcode, the sensor fitted within the scanner measures the intensity of the light in front of every bulb, generating a voltage pattern identical to the barcode. The scans from these barcode scanners are usually 100% accurate as they function on the basis of voltage and not reflection.

• 2D Camera Barcode Scanners: Designed primarily to scan two-dimensional (2D) barcodes, these barcode scanners can scan vertically. A two-dimensional (2D) barcode scanner comes with hundreds of tiny lights like CCD barcode scanners but the lights are positioned in multiple rows. When all the lights are flashed at a barcode, a digital image of the barcode is created which is then transmitted to the connected computer. Regardless of how you place the two-dimensional (2D) barcode scanner, it can scan, read, and decode data accurately.

Tips to Choose the Right Barcode Scanner

As already discussed, barcodes are created using dedicated software and barcode scanners are the point of sale (POS) hardware components that are used to scan and read these barcodes. To pick the right barcode scanner, consider the following factors:

1. The Type of Barcode that will be Scanned: The first step to consider while purchasing the right barcode scanner is to determine the type of barcode you would be scanning. Since there are barcode scanners that are capable of reading both one-dimensional and two-dimensional barcodes, you need to pick the one that meets your business requirements the best.

2. Image Quality of the Scanned Barcodes: You need to consider if your barcodes would be susceptible to damage or smudging. In case your barcodes would be exposed to such environments, you need to pick an advanced barcode scanner.

3. Location: Consider where you would be placing your barcode scanner. Whether it would be fixed at a certain location or would you require a mobile device would help you determine the perfect type of device you would require. Pick a corded barcode scanner for a fixed location and a wireless barcode scanner to meet mobile scanning needs.

4. Scanning Environment: You should also consider where you would be using your barcode scanner- outdoor or indoor. Different barcode scanners have different levels of durability. At the same time, there are barcode scanners that can withstand water spray, dust, and high temperatures. However, these devices are comparatively expensive.

5. Scanning Volumes: While purchasing your barcode scanner, you need to consider whether you would be scanning in bulk or individually. You need to pick a barcode scanner with fast speed and adequate battery life in case you have large volumes of printing needs.

6. Light Requirements: There are barcode scanners that are capable of reading in dim lighting and there are other devices that require adequate lighting for quality scanning. Therefore, you need to consider the environment where you would be placing your barcode scanner and check for the lighting in that location.

7. Scanning Distance: Different barcode scanners can scan and read from different distances, ranging from a few inches to several feet. Therefore, it is always recommended to consider the scanning distance while purchasing your barcode scanner.

8. Budget: The most important factor that you need to consider while purchasing your barcode scanner is your budget. Ensure that the device you choose fits your budget while meeting your business requirements perfectly.

Choosing a barcode scanner based on environment

Dust filled work areas requires additional precautions.

&#; Water and Dust &#;
A proper barcode scanner will include an Ingress Protection (IP) rating in their description. Ingress, the act of going in or entering, is an important factor when determining the best choice amount electronic devices. IP ratings are used to designate the encasing protection of any mechanical or electrical products. The higher the rating the more secure and durable the product is against solids, liquids, and pressures (designated K). There are other codes that represent additional protections as well. For situations where there is a lot of dust or watery conditions, higher IP rated barcode scanners which are more resistant to these situations will benefit you in the long run. If your work environment is more on the rougher conditions, try looking for a scanner with IP45 or IP65 for more durability.

&#; Fall damage
Accidents where items fall down and break occur quite often. A highly durable barcode scanner will have more resistances to damages from deliberate contact with solid objects or gravity related situations. Also considering that hard flooring like concrete has a higher chance in breaking items upon impact than carpet, durability will be important. Depending on the environment, looking for a solid scanner is important.

Bright and dark areas in a warehouse can affect barcode scanner capabilities

&#;Lighting is also an important factor to consider when choosing a Barcode scanner. Three prominent methods of scanners are:

&#; Laser Barcode Scanner
Laser scanners function optimally by shooting a laser beam off the barcode&#;s surface which measures the distance between the bars in the barcode and translates it into a number. With single and omnidirectional laser options, laser scanners have proven to be an accurate and reliable choice.

&#; Charged Coupled Device(CCD) Scanner
Using light detectors, the scanner lens takes a picture of the barcode and digitizes the image into a value for the terminal to read.

&#; Linear Image Barcode Scanner
Similar to CCD, the scanner takes a picture and translate the image into characters that represent the barcode. The only difference is the Linear function has a longer range. Since the image can be read easily, the image scanner can translate poorly developed or damaged barcodes.

Choose a barcode based on mobility

Fixed scanners example (Source: ZEBRA)

&#; Fixed scanners
Fixed (or presentation) scanners are mounted or standing scanners that are usually tethered to a point of sales system. Set to maximize scanning ability within a specific area, fixed scanners help in speeding up processing quickly (i.e. lines at a supermarket) and can even read partial and poorly printed barcodes easily. These scanners are attached to terminals and rapidly relay data per barcode to the terminal&#;s display screen.

Portable Batch Scanners example (Source: ZEBRA)

&#; Portable Batch Scanners
These battery-operated scanners transfer data to a computer which gives flexibility to move around and collect data on all your barcoded items. Ranging from various sizes, Portable Batch Scanners can function as a basic input unit or can come with an LCD screen and keypad to identify and adjust values. Typically these scanners store and export the data in a CSV format for ease of access.

Wireless Scanners example (Source: Uniinfo)

&#; Wireless Scanners
Similar to Portable Batch Scanners, these scanners store data in their memory and can free move around without a cord tethering in place. However, one additional feature allows wireless scanners data relay abilities to tethered database systems and gives real-time updates on products. Using Bluetooth, many wireless scanners have a connectivity range of about 30 ft (~10m) if tethered to a terminal. Using an inventory management app like BoxHero can tether Bluetooth to your mobile device (, tablet, laptop) and providing unlimited range around your warehouse.

Choosing Scanners based on Range

From tiny barcodes that can only be read from close range, to far away objects high above in warehouses, various ranges exist between barcode scanners.

&#; High Density Barcode Scanners
Used to read small barcode sizes down to 3mm, these scanners are specific for products that have limited space for placing barcodes.

&#; Standard Range Scanners
Provides a large range of scanner&#;s focal point which can scan barcodes both large and small. Main choice for most locations with standard sized barcodes like retail stores, warehouses, stadiums, etc.

&#; Extended Range Scanners
For specific purposes, these scanners can aim at low density barcodes up to 50 ft (~15m) away. Mainly in a warehouse scenario, where objects can be located high on top of shelves.

Choosing based on Other Features

Barcode scanning in a warehouse is quite useful.

&#; 1D Scanners
Scan function that can only be read horizontally.

&#; 2D Scanners
Scanners which have the capability to read horizontally or vertically. Because their direction does not matter, the position of the barcode also does not matter and can be read easily.

&#; Omnidirectional
As the name implies, projects multiple lasers lines to read barcodes in all directions. Used a lot with fixed or hands-free barcode scanners.

&#; Connectivity
Besides USB-cord connections, many wireless scanners are Bluetooth-enabled for data relay to the main terminal.

&#; Scanning Speed
Barcode scanners can vary in reading speeds and may use a single or continuous scanning function. The unit of measure all vary with different scanners having different methods of processing. Meaning some scanners process 25 frames per second while others have scan speeds of 120 images per second, etc. If fast input and processing is what you need, looking for a scanner with a continuous scan function would be ideal.

&#; Warranty
Like most electronic devices, limited warranties that come with scanners vary between 1-5 years complementary with an option for an extended 10-year warranty. It is a good idea to research into warranties for devices that are constantly being used and located in rough environments.

Barcode scanner technology has been around for many years and made great strides in development for optimal efficiency. Advancements in technology and applications will definitely have a lot more interesting, convenient, and life-changing features in the near future.
