Can I scan a barcode off a phone/tablet/computer screen?
Yes, but we suggest a scanner with a linear imager or 2D area imager scan engine because it can read barcodes easier & faster than a laser barcode scanner. A laser barcode scanner has to fight with the screen's reflection to read the barcodes while an imager takes a picture to decode the information.
How do I scan 2D barcodes?
You need a barcode scanner with a 2d area imager scan engine. Laser or linear imager barcode scanners will not work.
How does RFID technology work?
Radio frequency identification technology is an automatic way to collect product data quickly and easily. An RFID system comprises a reader (or interrogator), its associated antenna and the transponders (or tags) that carry the data. The reader transmits a low-power radio signal, through its antenna, that the tag receives via its own antenna to power an integrated circuit (chip). Using the energy it gets from the signal when it enters the radio field, the tag will briefly converse with the reader for verification and the exchange of data (or the Electronic Product Code). Once that EPC data is received by the reader it can be sent to a controlling computer for processing and management.
What are the advantages of RFID?
- RFID technology does not require line-of-sight reading.
- RFID tags can hold more data than bar codes.
- RFID tag data can be changed or added to as a tag passes through specific operations.
- RFID tags are more effective in harsh environments where bar code labels have problems.
What exactly is 'Scan Distance'?
Scan distance is the distance from a barcode scanner to the barcode itself.
- Stanadrd scanner ranges from 1" to 12" depending on the environment.
- Some scanners can scan when the barcode scanner is touching the label, known as 'contact' distance.
- Longer scanning distance (6" to 14") is best for industrial environments.
- Some devices have ultra long distance scan engines that can scan from 20+ feet away.
What exactly is a 'Scan Engine'?
One thing to consider when picking out a barcode scanner is the type of scan engine it uses to determine what you really need. The three scan engines are laser, linear imager, and 2D area imager.
Reads barcodes with a red laser.
- Most common type of scan engine.
- Can only read 1D barcodes.
- Most cost effective scan engine.
- Can read barcodes from 1" to 16" depending on laser engine. (Some scanners have extended range readers that can read barcodes up to 30 feet away.)
Takes a picture and decodes 1D barcodes.
- Can only read 1D barcodes.
- Can read barcodes from 1" to 12" depending on linear imager engine.
- Can read damaged or poorly printed barcodes easier than laser.
- Good for applications that requires aggressive scanning.
2D Area Imager
Takes a picture and decodes 1D & 2D barcodes.
- Can read 1D and 2D barcodes.
- Can read barcodes in multiple directions. The barcode can be upside down or sideways and it will still read. (Also known as omni directional)
- Reading results is almost instant compared to laser and linear.
- Can easily read barcodes on phone / tablet / monitor screens.
What is a 1D barcode and a 2D barcode?
- 1D is a category of barcodes with vertical black lines.
- Also known as linear barcodes.
- There are several fonts / languages of 1D barcodes.
- The longer the data, the longer the barcode becomes.
- 1D barcode is generally good for 8-15 characters.
- 1D and 2D barcode scanners can read 1D barcodes.
- Some popular 1D barcodes are: UPC-A, UPC-E, EAN-13, EAN-8, Code 39, & Code 128.
- 2D is a category of barcodes. Usually square or rectangle shaped with black pixels inside.
- Can store up to 2,000 characters. (200% increase over 1D barcodes)
- There are several fonts / languages of 2D barcodes.
- Can only be read with 2d imaging scanners.
- Some popular 2D barcodes are: QR code, PDF417, & Datamatrix.
What is a high density scanner/imager?
Some devices can be equipped with a high density scanner or imager which will allow superior barcode scanning performance on very small linear barcodes (3 mil or 0.003"), plus the versatility to read other common linear symbologies
What is a mobile computer good for?
Mobile computers are basically barcode scanners with a computer attached. They increase productivity and efficiency by increasing the speed, accuracy, and number of tasks completed everyday. To get the best out of a mobile computer, the right application needs to be used. Like a desktop computer or laptop, a wide selection of applications are available to give mobile computers many different purposes. Here are a few application examples that make mobile computers worth it:
Data Collection Applications
The following three applications are considered data collection applications since data is actively collected on the mobile computer to be edited, viewed, or transferred at a later time.
- Inventory / Warehousing - A mobile computer with an inventory application can show orders, current inventory, track shipments, & much more. With an integrated barcode scanner, tasks such as inventory or pick-and-ship are simplified since employees can walk around, scan products, and display accurate information on their mobile computer's screen.
- Fixed Asset - A fixed asset application can allow fast and simple tracking of assets in any business. Scan a barcode, view the asset on the screen, take a photo (if the mobile computer is equipped with a camera), view/edit the data, and moving on to the next asset can be done in minutes from a mobile computer.
- Check In / Check Out - Much like a fixed asset application but with the function to check in / check out items. Record the time an item was taken out, returned, who took it, add notes, and much more. Perfect for libraries and businesses that rent equipment internally and externally.
The following applications may or may not collect data on the mobile computer depending on its intended purpose. These applications require the power of a mobile computer with an integrated barcode scanner which grants efficient work flow.
- Verification - A verification application checks data on the mobile computer to make sure the data exists. For example, a spreadsheet of data is transferred on a mobile computer and when an employee scans a barcode, the application will check the spreadsheet to make sure the information exists. Additional features may include data lookup which pulls all the information associated with the barcode on the screen for viewing/editing.
- Data Building - A data building application can easily append prefix or suffix data to existing data. This is good for anyone looking to rebuild existing barcode data.
Custom applications can be created for any scenario with the right programming knowledge. Please contact us for any custom application requirements and we'll do our best to help.
What is drop rating?
Drop rating is a rating that manufactures give to their device to indicate how rugged a device is against a drop on concrete/ hard surfaces. Tests are performed by dropping the device at a consistent height on concrete. The rating does not mean the device will be damage proof but does mean that the device will be highly resistant to catastrophic damage.
Example: A device that has a drop rating of 4 feet means it can be dropped on concrete up to 4 feet. A device dropped at 4 feet may receive scratches but will be highly resistant against a complete failure. A complete failure is still possible but unlikely if it was dropped at 4 feet. If the device is dropped at a height higher than 4 feet then the potential of catastrophic damage increases.
4-6 feet is the standard height for walking with a device since most drops happen at waist height. If a device has no or a low drop rating then the device is suited best for permanently staying on top of a large desk or counter.
What is IP ratings?
Ingress Protection (IP) ratings is the standard rating for sealing electrical devices against dust and moisture. You will see most IP ratings as IP65, IP54, etc. Each number has a specific meaning. The first number indicates the degree of protection from moving parts (fingers, tools, wires, etc.) and dust — ranges from 0 to 6. The second number indicates the protection level against moisture — ranges from 0 to 8.
|IP Rated Enclosures|
|First Digit (intrusion protection)|
|0||No special protection|
|1||Protection from a large part of the body such as a hand (but no protection from deliberate access); from solid objects greater than 50mm in diameter.|
|2||Protection against fingers or other object not greater than 80mm in length and 12mm in diameter.|
|3||Protection from entry by tools, wires etc, with a diameter of 2.5 mm or more.|
|4||Protection against solid bodies larger than 1mm (eg fine tools/small etc).|
|5||Protected against dust that may harm equipment.|
|6||Totally dust tight.|
|Second Digit (moisture protection)|
|1||Protection against condensation.|
|2||Protection against water droplets deflected up to 15° from vertical|
|3||Protected against spray up to 60° from vertical.|
|4||Protected against water spray from all directions.|
|5||Protection against low pressure water jets (all directions)|
|6||Protection against string water jets and waves.|
|7||Protected against temporary immersion.|
|8||Protected against prolonged effects of immersion under pressure.|
IP Ratings look like this: IP65, IP45, IP54, etc.
Example: An IP65 rating means it is totally dust tight and is protected from low pressure water jets.
A device with no IP rating means it is not intended to work around heavy dust and moisture.
What is the difference between 'Batch' & 'Live' data collection?
If you are using a mobile computer to collect data then there are two methods to collect data: batch and live.
Batch - Batch means the data is stored on the device and will upload to a system / computer when the user authorizes it. Authorization means plugging it into a computer to transfer the data or going through the functions on a device to send data. Some mobile computers require software to transfer data. Batch devices will not communicate with each other (Example: If you have two batch devices, data will not be shared with each other). Good for simple inventory management and asset tracking.
Live - Live means data is transferred to a system, server, and other live devices in real time. Live devices require more time to set-up but is perfect for a high volume inventory management or asset tracking system that requires consistent accuracy and data management.
Most live devices can also do batch but batch devices can not do live.
What makes a device 'healthcare certified'?
Healthcare certified means the device has been covered in an antimicrobial plastic that can effectively prevent the build-up and spread of threatening bacteria and microbes. This includes the scan window, display surfaces, stylus, screws, wires, and plastic.
To be certified, each product is approved in a test lab to meet antimicrobial requirements. Antimicrobial surfaces provide effective protection but standard healthcare cleaning and disinfection procedures should still be followed. Healthcare certified devices are designed to withstand constant cleaning.
What Operating System (OS) should I use?
All mobile computer function with an Operating System (OS) — similar to an operating system on a computer (Windows, OS X, Linux, etc.) or smart phone (Apple, Android, etc.).
The functionality and applications available depends on what operating system you choose.
Windows Mobile / Embedded CE
This is the most flexible and feature-filled OS. Many third party applications are available from inventory, point of sale, banking, healthcare, and much more.
Windows Mobile is more common and can be found more in applications using cellular communication. Windows Embedded CE is lightweight & is preferred by developers making their own applications.
This OS is not the same as Windows on a computer which means applications that work on Windows 7 or 10 will not work on this OS.
This OS is the same OS found on consumer grade cell phones and tablets. Android is becoming a more and more viable option as an enterprise solution. For developers and users familiar with the Android OS, this can be a very cost-effective system to deploy. Depending on your application needs and your level of comfort with Android’s frequent updates, the OS presents some appealing cost and training advantages over competing platforms.
DOS / Propriety
Mobile computers with this OS can be found on basic mobile computers and will have very limited features. Available applications are limited to the manufacturer's library of applications or can be custom programmed with visual basic, C++, or propriety software. This OS is perfect for simple data collection or applications with simple functions.
This OS used to be the standard in mobile computers. There are still a few manufacturers that use this OS but applications are limitted. If you have Palm OS with a working application, this can be a cost effective solution.
What types of mobile computers are available?
An important consideration when buying a mobile computer is the type of mobile computer that you want to use. Here are a few types of mobile computers each with its own advantages depending on your required usage.
Basic mobile computers contain the most basic features for entry level applications (simple inventory, verification, etc.). Basic mobile computers collect data in batches.
