Choosing the Right Barcode Scanner for Your Retail Store

Barcode scanners have become commonplace important tools in retail. They speed processing time and thus can have an impact on customer experience in your store. But which barcode scanner is the right one for your store or retail business? The biggest factor is the use case. If you have a few small stores like I did, I used them at the POS, but not for inventory. When I ran larger organizations, we used the scanners for physical inventory which saved a lot of time.

 

Scanners are only as good as the connectivity between the device and your POS database. In other words, you can buy the best scanner on the market, but if your POS system is not set to handle it, then it's a moot point. All POS systems will handle scanners for the cash register functions — this is the most common use case. In fact, the most popular POS systems come equipped with the barcode scanner in the box. But when it comes to warehouse or inventory functions, your system may not be ready. So check your current software's functionality before making a decision on which scanner to buy. 

Here are the most common terms and considerations you need to consider as a retailer when deciding which barcode scanner to buy. 

Scanning Engine (Type) 

There are three basic types of scanners. Each one reads different types of barcodes and labels in different ways. 

Laser

The most popular and well-known scanner is the laser.

It reads simple barcodes on a 1 dimension (1D) plane. It can read from two to 12 inches away, but there are some models that can read from 20 or more feet away. In fact, there is a Wasp barcode scanner that can read from over 35 feet away. These scanners are the most common due to their low cost. But they are limited in what they can do.

And the laser diode will often time frustrate the user when trying to scan. 

Linear

These scanners can only read 1D images like the laser versions, but they do it very differently. The laser uses a red light to read the black and white spaces in the label. The linear scanner actually takes a picture and then analyzes the picture. This speeds up the processing and scanning time. And prices for these models have become very similar to laser models. But the accuracy and quality of the scan are better. 

2D

These are the best scanners because they can read any of the barcodes. As it sounds, it can read in a two-dimensional manner. This yields a lot of benefits. First, it allows you to scan in any orientation. With the scanner types, you have to align the scanner on the same plane as the label, but with the 2D scanner, you can read it portrait or landscape it doesn't matter. Some manufacturers will refer to this as omnidirectional. This scanner also takes pictures like the linear models and that's why many companies refer to their scanners as 2D linear scanners. 

Wireless vs Wired

Obviously, wireless is all the rage today. And we all love our mobile "untethered" lives. But there is a big cost difference between the two.

Even though the scanner is categorized as wireless, it still has to be connected to a computer to work. So, the common application is to set a cradle next to the computer that can not only plug into the POS device for ​a connection, but can also serve as a charging station for the scanner. This also means that your POS computer doesn't need any wireless device support. 

There are many scanners that can work through the "cloud" versus directly into the computer. These devices use bluetooth to connect and can be linked to a mobile device as well. The app on the device gathers the information and then sends it to the server where the database for your POS system is stored. Often times, this is an online cloud server and not a "box" physically in the store. 

Some Good Questions to Ask When Choosing a Barcode Scanner:

  • What types of barcodes are you reading? Considering the information shared earlier in this article, the types of barcodes you are dealing with will determine the right scanner for you. In other words, 1D or 2D codes
  • How often will you use the scanner? In my experience, investing in a deluxe model scanner when you only use it for physical inventory is not a good investment.
  • Will it be used indoors or outdoors? This is important if you do shows or other outdoor retail. Scanners are not very durable in general. So, if you are traveling with it or using it outside, invest in one that can handle the elements. In Texas, for example, you need one that can handle the heat. 
  • What's the distance? While not as relevant to most retailers, how far away the barcode scanner can be from the barcode can be an issue. This mostly applies to warehouse applications. In other words, if you can be within one foot of the barcode, don't buy a scanner that can read from 20 feet away — it's not worth the extra money. 
  • Can you be connected directly to a computer? This is a big one. While all scanners have to be connected to a computer or tablet to function, if the scanner can be plugged directly into the computer, you can save yourself a lot of money. This is common with scanners at the POS.
