Laser Barcode Scanners aren't the only option in a Rugged PDA

Laser Barcode Scanners aren't the only option in a Rugged PDA

Today we move onto the bar code scanner section of our Understanding the Rugged PDA Series.

If you want to learn about bar code scanners then we have a great series right here, this blog however takes a more layman’s view on your choices when buying with a Rugged PDA.

So where do we start?  The most frustrating thing for me personally (And I know I get a bee in my bonnet about this!) is customers who come to us pinching the pennies on margin but with no clue about bar codes whatsoever!  The latter will cost them way-way more as they fumble their way through their solution every day.  The first thing to consider is what bar codes you are scanning and if you need a 1D or 2D scanner.  Now as you might have read from the post link above, things aren’t so clean-cut these days so i’m going to make some bold statements in this blog!

1D or 2D

Most Rugged PDA’s have the choice, some have dropped their 1D all together with 2D scanners now rivalling 1D ones for performance and cost.  However a 2D option is always going to cost you more so if you are definitely not going to need it, go for 1D.

Laser or Linear

Linear has all but caught laser up in terms of speed, efficiency and performance.  It’s also cheaper, smaller, lighter, easier on the battery and has no moving parts unlike the mirrors required in Laser bar code scanners.  Having said that in a PDA if you;re breaking the scanner then you really are probably abusing the device!  If you want to save a bit of money then we’re finding Rugged PDA’s with a budget linear imager option are often more than enough for those considering it.

Bar code scanner manufacturer

Again this is really getting tough to decide between who has the best scanner these days and personally, as long as the scanner manufacturer is from a well-known brand, you;re fine.  Cipherlab, Motorola, Honeywell make the best in our opinion.  Intermec are also very good and found in a lot of kit, Opticon 1D lasers are probably the best on the market, Motorola’s Blockbuster 2D engine is probably the best 2D scanner on the market but unless you really are scanning vigorously, you’re not really going to know.

configuration and setup

What does matter is your scanning environment.  Lighting, being indoors or outdoors, the way colour is affected and where the bar codes are situated all usually require some configuration of the scanner.  How much and how well you can do this can be the difference so we always steer people with specific and unusual needs to certain technology.  Motorola and Intermec scanners for instance are all not only very highly configurable with different light settings and all kinds of tricks to use but they also setup software to give you access to this.

Scanner types

If you need to scan a bar code from 3 metres away then you need a long-range scanner a normal one won’t do!  There are also 2D scanners that can scan near and far and there are also scanners suited to high density bar codes too.  Always let us know what you’re scanning so we can help.

No Scanner Option

Yes we’re going to end this blog about bar code scanners, with a note about not buying one!  As rugged and mobile solutions become more mainstream there are lots more customers who don;t want a bar code scanner.  There are also more and more RUgged PDA’s that give you a “no scanner” option and one that we can install them in later!  This can have serious cost reduction on the PDA so it’s no longer the case that you have to buy scanner features that you’re never going to use.

OK, told you it would be layman’s terms, Monday we’ll be looking at RFID Readers, have a good weekend everyone!

Happy Rugged New Year 2012!

1 01 2012

So, 2012, the future is here already!

We wanted to thank everyoine here for heloing us grow our blog hugely throughout 2011 and also to wish all our readers a very special happy new year.  Here’s hoping amidts all the doom and gloom, that we can continue to shine a ray of sunshine…..well into data capture at least!! ;-)

We’re going to see some trends push on this year, thats for certain and we’ll be seeing some fantastic new technologies, products and innovations this year too.  Some we can talk about, some we can’t but we’re bursting at the seams when it comes to this so watch this space, come back often and of course let us know if there’s anything you want us to talk about here.

We’re going to kick off 2012 with a series of “whats next in Data Capture” blogs to tee us up nicely for a technology packed exciting time for anything mobile or data capture.

We’ll be back tomorrow with more…

Selecting the right Barcode Scanner

Barcode Scanners Come in all shapes, sizes and price too.

Barcode Scanners Come in all shapes, sizes and price too.

Up to this point then we’ve talked about everything you need to think about when creating a barcode scanning solution and this blog sets us up to talk about the barcode scanner hardware you can use.

Barcode Scanners

You can talk about barcode scanners in many different ways, for the purposes of his series of blogs i’m going to start off looking at them form a “budgetary” perspective.  In a nutshell you can buy barcode scanners from about £30 upwards from reputable and decent manufacturers and in fact you can pay over £500 for a fully rugged, wireless one too, so whats the difference?

Firstly the £30 budget barcode scanners are really quite good if you can learn to live with some of their compromises.  These scanners come with a low power, CCD Barcode Scanner which gives you about 0 to 3 or 4 cm range when scanning barcodes.  They tend to not have an efficient ergonomic design but most of them can be set up to scan automatically and give you a basic, inexpensive scanning solution that can hold its own in a small shop, office or even more scenarios.

Next up are the mid-range scanners which take the budget from £45 to £60/70.  These start to have better, but not perfect ergonomics, they still tend to use CCD technology but with a far better range and they also tend to scan more symbologies too with better scan engine performing the scanning deciphering.  Most come with cradles and start to give you decent retail options and the scan rates are a lot faster so they are starting to become quite efficient.  You also start to see some laser scanners in this category from brands like Zebex and Cipherlab which give far better scan rates, are better at handling range and give better flexibility when scanning.  More on that below.

Top of the range scanners push the budget up to about £70 to £150 and this is where the Motorola ls4208 as seen on most self-service scanning counters you use such as Ikea and B&Q.  These tend to be highly efficient in design with micro switch triggers, great ergonomics and fast, accurate laser scanning technology.  Accessory ranges become larger as do the number of leads to connect them to more than PC’s or USB based Kiosks.  IBM, Nixdorf ec tills can be connected to and these scanners really are the top of the range when it comes to scanning.

The difference between CCD and Laser barcode scanning technology

It used to be that CCD was simply a cheaper technology and that’s exactly what you got in the end product.  However CCD technology has come on so far in the past few years that it is now surpassing Laser technology when it comes to barcode scanning.  Motorola in fact have already announced plans to replace some Laser models with pure CCD scan engines and Intermec have also just release the SG10T which is also a budget CCD scanner.  The benefits of CCD are that it’s cheaper, lighter technology to start with so barcode scanners can be priced at a lower point.  They have no moving parts so are inherently more rugged than Laser scanners that use moving mirrors to generate the “Red Line” and they are in fact including scan engines now that seem to be able to read certain barcodes more efficiently than Laser scanners.  We’re seeing that from every day tests we perform here anyway.

laser scanners are still more efficient, and perhaps their main asset is that they still perform better in different lighting conditions as the laser is less susceptible to light and they give a bit better flexibility when scanning but it’s getting close these days

Rugged Scanners

Most Barcode scanners have a degree of “dropability” when it comes to ruggedness but you still need a rugged scanner if in a dusty or wet environment or indeed you need something that can be dropped from higher than 5ft.  Wireless scanners also demand a higher degree of ruggedness too so you often see the rugged scanners also coming wireless flavours.

2D Scanners

As 2D barcodes hit their tipping point we’re seeing more 2D barcode scanners hitting the market.  The technology is inherently more expensive but we’re still seeing mid-range ones appear such as the Cipherlab 1500 series.  The 2D scanning technology in these scanners is almost up there with the best laser scanners too these days.

Wireless barcode Scanners

Wireless scanners come in a range of flavours, Firstly we have the retail designed barcode scanners which come with a charger/cradle that connects them to the till.  These tend to use Bluetooth to communicate with the cradle which in turn connects to the host hardware.  You can also get WiFi based scanners that can talk through your local Network and these are used where scanning can be made to communicate directly with servers or PC’s that are stored at a greater distance.

The fastest growing bunch of wireless scanners though has to be the HID or VCOM compatible ones, much like the Cipherlab 1660 series.  These are basically Barcode Scanners that will scan direct to any Bluetooth enable host device without any cradles in between and are the type that iPAD, Andrpidn and PDA users can use to scan directly into their barcode Scanning Solution.  We’re starting to see retail style scanners now come out with this type of technology which will open up the EPOS market somewhat.

Thats Scanners in a nutshell then.  We’ll talk a lot more about these categoreies in our series on the technology next week.

Assessing your Barcode Information and ID Needs

9 12 2011
 
Barcode Data Structure is very importanmt to your barcode solution
Barcode Data Structure is very importanmt to your barcode solution

As part of our barcode solution guide we’re looking at how you assess your barcode information and Barcode technology ID needs.  This is a simple look at what you’re using your barcode for and what kind of data you will want to store in it.  It’s usually a trade-off between size of barcode and complexity of data but there’s a little more than meets the eye too!!

Tip 1 - Is your barcode going to be simple code that will be used to ID an assess for use in your software application or does it need to store more than this, offering more complex data up to the user.  Addresses are stored in parcel barcodes, web links in many QR code marketing barcodes and even sub codes that are also designed to be “People readable” as well as machine readable.  Airline tickets use a code that airline staff can easily read information our of like the gate and flight numbers for instance

Tip 2 - What kind of data will need to be held.  If storing numeric only then you can choose good robust barcode symbologies that will be small and efficient.  Add letters and other characters and your choices become more restricted.

Tip 3 - How do you check for mis-reads or invalid barcodes.  This is essential as all barcodes mis-read from time to time.  A good data structure behind your barcode solution will mean you can provide a robust response to any misreads.

Tip 4 - Is the data or ID being used robust enough for future usage.  What if your solution grows, will the barcode and data structure used be robust enough to cope with this growth.  Your barcode will grow, especially if you can’t use numbers and letters.

Barcodes usually grow as your solution grows!

Barcodes usually grow as your solution grows!

Tip 5 – Will you need to store lots of data, but are restricted to using 1D barcodes?  Well there are a range of High Density barcodes that can be used to store larger amounts of data.  They’re nowhere near as good at 2D barcodes doing this and you might need a better barcode scanner to read them but it is possible.

Tip 6 – Is 2D an option?  They are far more flexible, more robust and they are the future of barcode scanning.  However they’re also more complicated to manage and generate and they need more expensive 2D barcode scanners to read them which adds up to a small cost increase but they will make for a more future proofed solution.

Tip 7 – Doube check that what you have come up with is as flexible as possible.  We always ask clients to take a best case scenario for their solution and business, double it and see if the solution still works for them.  Changing ID’s in barcodes can be a very costly and complex thing to do half way through so it’s worth getting it right first time.

Tomorrow we’ll continue by looking at Barcode Label Selection.

Barcodes and Barcode Scanners comin all shapes and size - We're here to help!

Barcodes and Barcode Scanners comin all shapes and size - We're here to help!

Morning everyone, it’s a miserable chilly day here this morning in Liverpool, we’ve had rain, sleet, hail and thunder here in all in the past 12 hours, but we’ve got barcode scanners, rugged PDA and data capture to keep us going!!

We’re putting down the PDA and turning our attention to Barcode scanners this week as it’s time to update all our info on barcodes and barcode scanners with so many changes happening in the past 12 months.  I thought it would be great idea to sum this all up in 1 big barcode scanner guide!

We”ll take a look at barcodes first, explain what the heck are they, what kinds can you use  and why there are so many different versions.  Then we’ll talk abotu the kit used to scan them which should take us through a quick neat guide to barcode scanning technology.  I’ve laid out the contents here as we go along so it’ll create one big guide at the end.

The guide will be layman’s terms, aimed at helping the typical user that’s probably got better to do all day than learn about barcodes! but the aim here is to keep it simple and full of information to get you going and keep you running.

We’ll also keep coming back to the guide in order to keep it fresh and new.
