The first barcode was introduced on June 26, 1974. A 10-pack of Wrigley’s Juicy Fruit chewing gum was scanned at 8:01 am at a Marsh supermarket in Troy, Ohio. Since then, the use of barcodes has exploded and can be found almost anywhere and on virtually any product. As barcodes have evolved, so has the hardware used to scan barcodes. In this article, we will help simplify the task of choosing a mobile computer (also known as barcode scanners and mobile devices) to scan barcodes.
If you’ve ever looked closely at a mobile computer datasheet, you’ll likely see up to 40 different specifications listed. Forget those, for now. Here is what you should focus on:
Five Primary Decision Factors
- Scan Range
- Form Factor
1. Ruggedness: In what type of environment will the device be used?
In what type of environment are you working? Is the environment dusty? Wet or humid? Cold? Is there potential for the device to be dropped from 4 feet? 10 feet?
Based on the environment, there are two main factors to consider:
Drop resistance: Nearly all mobile devices will have a drop spec. The higher the drop spec, the more rugged the device. For someone working in a clean, retail environment with carpet flooring, a 4′ drop spec may suffice. A busy warehouse with forklifts and ladders to reach pallet racking, a 10′ drop spec may be more suitable.
IP rating: The IP rating, or Ingress Protection Code, is a standard that rates the degree of protection a mobile device case provides. If you’re working in a clean, non-rugged environment, an IP rating likely will not be a factor. In cases where dust, moisture, freezing temperatures, and other elements are present, you’ll want to consider the IP rating. Some of the common IP ratings include:
- IP54: Partially protected against dust and splashing water
- IP65: Protected against dust and water spray
- IP67: Protected against dust and water immersion for a limited time
- IP68: Protected against dust and water immersion for continuous submersion
2. Scan Range: How far away is the barcode you need to scan?
Depending on the manufacturer of a mobile computer, the scan range terminology may vary. There are three primary ranges when it comes to scanning:
- Standard-range: The scanner will scan a barcode close to a few inches and up to 30 inches away.
- Mid-range: A mid-range scanner will scan up to three or 15 feet away, depending on the model. These types of scanners are sometimes referred to as flex-range.
- Long-range: A long-range scanner can scan as far as 50 to 70 feet. These types of scanners are sometimes referred to as extended-range.
The scan range you require will, again, depend on your environment. If you are on a forklift and scanning boxes placed high up on pallet racking, then a long-range scanner may be required. If you’re working retail where everything is within close range, then a standard-range scanner may suffice.
Keep in mind that while the ability to scan at different distances is dependent on the scan engine of a device, the size of the barcode also plays a factor. You should not expect to scan a 1″ square 2D barcode placed 70 feet away with a long-range scanner. The size and lighting conditions of a barcode will play a factor.
3. Camera: Do you need to take pictures?
Often when a mobile device is used in shipping and receiving, a built-in camera comes in handy for documenting damaged shipments, packages ready for shipping as well as documents. Not all devices offer a camera option, and so if a camera is essential to you, you’ll want to begin filtering on devices that provide a camera option.
4. Form Factor: What style of device best suits your needs?
When we talk about “form factor,” we refer to a mobile device’s physical properties. For example, “form factor” may be a physical keypad, a built-in pistol-grip, or a wearable device that can strap to your wrist. There are several options available; however, the most common options are:
- Physical keypad: A physical keypad, versus an on-screen keyboard, is more glove-friendly. Often physical keypads will come in different layouts, for example, a 29-key numeric, 38-key numeric/function, or 47-key alphanumeric.
- Pistol-Grip or Handheld: For non-stop, daily scanning, a device equipped with a pistol grip, or gun, tends to be more ergonomic. For more casual scanning, users may prefer a handheld version. Handhelds are also referred to as bricks or straight-shooters. Not all mobile devices offer a pistol grip. For those devices that offer a pistol grip, the handle may be built-in, where others offer a bolt-on or slip-on option.
5. Price: How much do you want to spend?
When it comes to mobile computers, typically, you get what you pay for. The more rugged the device, the more features it has, the higher the price. Be willing to pay for the features you need. Getting a proper device will make a difference versus buying a cheaper device lacking the options you need. If you don’t need specific options, don’t get them, and the price will reflect that.
Secondary Decision Factors
So, we have covered off the five primary factors when choosing a mobile device. There are some secondary factors to consider as well, and these are:
- 1D (Linear) or 2D (Data Matrix) Barcodes: Do you need to scan 1D, 2D, or both 1D and 2D barcodes? Check the specs of the device you choose to ensure the scan engine can handle the type of barcode you need to scan.
- Mobile Data Support: Will wifi communication suffice, or do you need mobile data support? Some mobile computers offer SIM card options. If this is important, check the device specifications to ensure mobile data is supported.
- Accessories: Available accessories will vary based on device models. Accessories may include holsters, extended batteries, multi-device charging stations, forklift mounts, rubber boots, and more. Check to see what is available for the device you are considering.
- CPU/Memory/Storage: The performance specifications of a device typically isn’t something to worry about too much. Most devices today offer plenty of CPU horsepower, ram, and storage memory. Unless you have specific requirements, performance specifications will meet 99% of the user’s needs.
- Charging Accessories: A method to charge a mobile device typically needs to be purchased separately. For some mobile computers, charging accessories are limited, so the choice is simple. There can be several options for other models, including single or multi-battery chargers, single-unit docking stations, multi-unit docking stations, and more. Furthermore, charging stations will need a power supply and cables, which are often sold separately. Make sure you select all pieces required when choosing a charging option for your mobile device.
A Word About Operating Systems
In 2018 Microsoft announced the end-of-life of their Windows operating system for mobile devices. Therefore, the Microsoft Windows CE and Embedded Handheld options are slowly phasing out and is being replaced by Android. Unless you are already running Windows devices and want to continue so that all devices are the same, there is no good reason to go with Microsoft Windows. Choosing Android will help future-proof your investment in mobile devices. As for Apple iOS, the operating system doesn’t exist for mainstream, commercial mobile devices.
What is Mobile Device Management (MDM)?
Mobile Device Management, known as MDM, enables IT administrators to control, secure, and enforce policies across mobile devices by using software. There are many MDM options available, both available from device manufacturers and third parties. An in-depth discussion is out of scope for this article. MDM is not for everyone. For those looking to lock down devices to prevent users from performing specific actions, there are third-party apps like SureLock and SureFox available.
Should you Consider a Comprehensive Service Plan?
Major mobile device manufacturers offer extended service plans for the devices you purchase. While devices typically come with some warranty, driving over a device with a forklift or dropping it in a bucket of chemicals isn’t covered. Depending on the ruggedness of your environment, an extended service plan can be a good idea. Depending on the service plan, damaged devices are replaced, worn batteries are replaced, and damage is repaired. Common extended service plans range from three to five years, and turnaround times vary from the next day to up to five days or more.
Don’t instantly dismiss an extended service plan when buying a device. While the cost for a service plan can add 15% to 25% to the cost of a device, it can help reduce the overall total cost of ownership.
Who are the manufacturers?
There are a lot of mobile computers on the market. The three big manufacturers are Datalogic, Honeywell (Intermec), and Zebra (Motorola & Symbol). Each manufacturer offers several different models of mobile devices, with each model available with different options.
The choices can be overwhelming, hence the purpose of this article. While you can reach out to vendors for assistance, you must do your homework and know the features you need and how the device will be used. A vendor can provide guidance, but the onus is on you to decide what will work best for you.
Why not just use a consumer-grade smartphone?
Why not wear running shoes to climb Mount Everest? Matching the proper tool to the task at hand typically yields the best results. Consumer-grade smartphones don’t use scan engines. Instead, the built-in camera is used to read barcodes. Smartphone cameras are not efficient when it comes to reading barcodes. The cameras can be slow compared to a scan engine, users typically need to be within about 12 inches to read a barcode, and reading off-axis, dirty, or damaged barcodes becomes a challenge.
Smartphones will not be as rugged as a purpose-built mobile device, and this can often end in a higher total cost of ownership when devices get damaged and need replacement.
For those that need to scan all day long, the ergonomics and scanning performance of a mobile device will out-perform a consumer-grade smartphone – hands down.
