If your barcode scanner has internal storage and you accidentally move out of range, you won’t lose your scans. This fail-safe feature can eliminate a lot of frustration. If you’re doing inventory, the information is stored in the handheld scanner so you can upload it to a computer later. Internal storage: Many barcode scanners have internal storage. In order to operate one of these scanners, you simply move the barcode into the unit’s field and it automatically scans. These models don’t require that the user activate them they’re always ready to scan. FunctionsĪuto-sensing: This feature is typically found on a fixed or desktop unit, such as you might find at a self-service checkout station in a grocery store. Be certain the barcode scanner you’re considering has the range you need in your workplace. When considering a barcode scanner, remember that there are a number of factors, such as walls, other WiFi devices, and stacks of inventory, that can reduce that maximum range.

Range: All wireless technology, whether Bluetooth or WiFi, has a maximum range.

However, in most instances, you’ll need a portable barcode scanner that utilizes either Bluetooth or WiFi technology. If all the items that need to be scanned are brought to you, such as at a checkout register, you can save money by choosing a barcode scanner that plugs directly into your laptop or computer. Unfortunately, that design proved impractical due to the limitations of technology at the time. The initial barcode design was in the shape of a bull’s-eye. Additionally, an image scanner is better at interpreting worn or damaged barcodes, and it can read images off a screen, which is essential for customers who prefer to use coupons on their smartphone instead of printing them. An image scanner can read left to right as well as up and down, so it can interpret a whole image. Since a laser scanner scans from side to side, it can only determine how wide and how far apart the bars are. While that isn’t precisely how it functions, it does focus on why it differs from a laser scanner. The easiest way to explain an image scanner is to think of it as being like the camera on your phone. If your laser scanner isn’t rugged, the first time you drop it could be the last time you use it.
Since the process involves delicate moving parts, these scanners need to be tough and impact resistant. It does this by registering the amount of light reflected back to the unit: white reflects light while black absorbs it. The laser moves from side to side, registering not only the width of the black bars but also the white space between them. Like it sounds, a laser scanner uses a laser along with a reciprocating mirror or rotating prism to scan barcodes. It’s important to understand the difference between the two or you may end up with a scanner that doesn’t work with your barcodes. The problem is they can look exactly the same.
There are basically two types of barcode scanners. If the unit fails to read a barcode, it’s usually the fault of the barcode, the operator, or an environmental condition, not the scanner itself.
Barcode scanners have a high degree of accuracy.
