Advantages and Disadvantages of Handheld 2D Barcode Scanners By Neil T Jones

There are two main sub-types of handheld 2D Barcode Scanners:
2D and 1D. The sales of 2D Barcode Scanners are increasing at an
astonishing speed. On the other hand, those of the 1D scanner
remain stagnant year after year. Potential users of 2D Barcode
Scanners would most definitely desire to learn about the
advantages that they offer. Read on to find out the many
advantages of 2D Barcode Scanners. The article also points out
some disadvantages of using the same, as both advantages and
disadvantages need to be taken into account before deciding on a
device.

Advantages

The foremost advantage of using a 2D barcode scanner is its
capability to read and decode 2D barcodes. Among the 2d barcodes
currently in use, some are Data Matrix, Aztec, QR Code and Han
Xin. It is possible to store a larger volume of data with 2D
barcodes than with 1D barcodes, in the same or even less
physical area. It is also possible for product manufacturers to
squeeze in thousands of characters in a single 2D barcode.
Moreover, 2D barcodes have the added capability of reading
barcodes omni-directionally. Handheld 2D barcode scanners are
characterized by an image sensor which is used to capture an
image from a particular barcode. Following this, the image is
run through a software decoder program installed inside the
scanner's firmware. This software decoder program is capable of
locating the barcode on the basis of a particular barcode's
unique attributes, irrespective of its orientation.

This unique feature eliminates the need for changing the
position of the scanner with the different positions of the
barcodes. It is not necessary for the barcode scanner to ensure
orientation with the barcode it is to read. This considerably
reduces total reading time and user fatigue.

The technology that runs the image sensor is the same as that
behind the modern digital camera. One major difference between
the two, however, is that 2D barcode scanners deploy a greyscale
imager as opposed to the color imager used in digital cameras.
Owing to the fact that it is an imager, a lot of scanners are
capable of clicking a picture and transmitting it to the
connected computer. There are a lot of uses of this wonderful
feature, including taking snapshots of signatures for delivery
proof, damaged packages, recognizing forms and processing off
scanner images.

2D barcode scanners are the last word in reliability. A 2D
barcode scanner possesses only a single moving part. That is the
trigger switch.

Trigger switches used by scanners are rated at as many as
millions of activations. Failure for this to function is very
rare. This translates to a potential for zero down time for
customers. This leads in turn to improved efficiencies, reduced
level of frustration and decreased cost of ownership. This is
not an all-exhaustive list of advantages offered by 2D barcode
scanners vs. 1D barcode scanners. There are other advantages.
However, 2D barcode scanners are not exactly without
disadvantages. Though the pros clearly outweigh the cons, the
user must be educated about the disadvantages while making a
purchase decision.

Disadvantages

The first disadvantage of 2D barcode scanners is their price.
These scanners deploy the latest technology and are continuously
being modified according to modern technology. Image sensors
with increased number of pixels are being installed, decoding of
algorithms at a higher speed is being made possible,
illumination and aiming patterns are being modified and improved
upon. As a huge amount of investment goes into the 2D barcode
scanners, their prices are a bit higher than 1d barcode
scanners. However, with time, the gap between the prices of the
two types of scanners is decreasing. The prices of all scanners
are such that they are considered to be commodities.

Another drawback of 2D barcode scanners is their working range.
‘Working range' means the point farthest from which a scanner
can read a barcode minus the closest point from which the
scanner can read a barcode. For example, if a scanner can read a
UPC, a barcode, from the closest distance of 2 inches, and it
can read the barcode at the farthest distance of 10 inches. Then
the working range of this particular scanner would then be; 10
in – 2 in = 8 in. On the other hand, a 1d barcode scanner would
be capable of reading the same barcode from the farthest
distance of 18 inches and the closest distance of 1 inch. The
decreased working range of a 2d barcode scanner might prove to
be a hindrance in certain applications.

Individual Health Insurance Tips By Zane Madisson

When it comes to health insurance many people put off making a
decision because they think it costs too much. As a matter of
fact, a great portion of Texans are walking around tempting fate
without health insurance. This is unfortunate because you might
be surprised at the many available health insurance options.

You already have the abilities to choose a great health
insurance plan. If you have ever had to analyze a purchase

great to have a private hospital room, it may not be necessary.
On the other hand, if you have great value for your privacy and
you have the extra funds now, go ahead and get it, because it is
a whole lot more expensive to pay for it out of pocket.

There are a whole lot of money terms when it comes to insurance
policies. You have probably heard about them at one time or
another. Terms like co-insurance or co-payment. These mean there
is a portion (usually a percentage) of the total cost above a
deductible that you will be responsible for. Speaking of
deductible, this is the amount you are responsible for in full
before insurance starts paying its share of the total cost.

You want to consider your health insurance in the long run
also. Let’s face it, none of us are getting younger, and your
health needs are going to get greater the older you get. Take a
look at the insurance policy you are most interested in and
examine it for long term health care options.

What types of illness run in your family? You might not get
them, but you are at higher risk for it so why not invest in
insurance that covers this possible eventuality.

With medical costs today, you might find yourself in a
situation where you require serious medical attention. With that
comes extensive, hard to pay, sometimes lifelong bills. Do you
really want to put your finances in this kind of situation? How
about your family, you don’t want to have them need to help you
with your bills.

So get a free quote today and you will be buying yourself some
reassurance that you are going to be ok when you end up in the

The SD Card For Digital Cameras

With the world of technology booming, sometimes it’s hard to keep up with all of the new things out there. Advancements in every technological field seem to come out on a daily basis. One such advancement has actually been out for awhile. The SD card is a handy little device that has the capability to improve your life and make it easier. What exactly is an SD card and what is it used for? Let’s look at the facts.

An SD card stands for a secure digital card. SD is a non-volatile form of memory. This means that even when it doesn’t have power going to it, it can still store your files. This makes the card very flexible and it can be used in a variety of ways. SD cards were first marketed in 1999 by Sandisk, Panasonic, and Toshiba. These industry giants agreed to adopt this technology and make it available to the masses. The SD card became very popular and many people have used one over the years.

The most popular use for an SD card is in cameras. They make sharing photos on a digital camera extremely easy. With most SD cards you can store hundreds of photos before you have to clean it off. The great thing about SD cards is that you can simply take it out of your camera and stick it directly into your computer. You can then remove the pictures and store them on your computer or on a CD. This makes your photo storage capacity virtually limitless. You no longer have to get film developed in order to keep a picture. Just take it off of the SD card and put in onto your hard drive. This opened up a world of possibilities for photo enthusiasts and made things more flexible to deal with.

After the SD card took the world by storm, it has experienced a few growing pains along the way. With the popularity, an increase in options has presented itself. More companies make multiple sizes of the SD card. While it may increase performance and memory, it also has managed to confuse many customers. The cards look the same and are the same shape. However, they might actually be a different size than you need for your camera. This has created compatibility issues from device to device. This means that before you invest in an SD card, make sure it is the one you need. Don’t buy one that isn’t going to fit your device. If you do, you might end up becoming frustrated like many others who have purchased the wrong size of SD card.

Overall, SD cards have revolutionized the industry. You can store a lot of information on a tiny little card that will easily fit in your pocket. This allows you to take vast amounts of information and photos with you on the go. Regardless of where you’re at, you never have to worry about leaving your photos at home. Just pick out the right SD card for you.

The Financial Crisis and Emotional Intelligence – What it Teaches us About Our Romantic Relationships

You may be wondering why I am discussing the financial crisis in a newsletter about relationships! Don’t worry, I have not lost the plot… what is happening at the moment in the world of banking can be related back to some fundamental emotional problems and the way that we try to compensate for these through materialism. We can therefore learn a great deal about our relationships and how to avoid the equivalent to the credit crunch in our personal lives.

The problems we have seen in the financial world have affected us all. We will all pay a price for the imbalances that have been allowed to develop around excessive amounts of unsecured borrowing. In short we have been living way beyond our means and the system has caught up with us. Somehow we thought that wealth and material success would make us happy. Perhaps we thought that a bigger and better house or flashier car would be the answer. We haven’t notice it, but the developing word has been paying a price for our greed for many years and now we must also face up to reality.

We can use the Psychology of Vision model to understand what has gone wrong – in fact it has been predicting the sort of problems we are facing now for years. We can understand them as an example of Independence. As individuals we become Independent to avoid being Dependent on other people for our success and happiness. Underlying this is a subconscious decision to never rely on another person again so that we cannot be let down and hurt as we were in the past. This fear of dependence comes from our earliest experiences in our original families whenever bonding is disrupted. In such situations we often take on guilt and develop low self-esteem for having failed significant people in the family – usually our parents and siblings.

Rather than feel our guilt and sense of failure we decide to avoid such close relationships with people and at the same time suppress our emotions so that we can never feel that dependent again. In work and life we will begin to replace the intimacy and love within close relationships with money and material goods. We try to control others to bring us the material success that we want and to make sure that our fear and guilt is never triggered through failure. Everything we do to achieve success involves things outside us rather than trying to find contentment within – this is the crux of the problem and has led to the credit crunch.

Any early successes as an Independent just encourages us to greater Independence – it seems to be the strategy for happiness. The more we get, in terms of money, power and influence, the happier we conclude that we will be. This is what has happened in a collective way in our society. We have used our material wealth to distract us from the inner quest – both emotionally and spiritually. We have assumed that we can succeed without emotionally meaningful, intimate relationships and have used materialism to distract us from the need to heal our fears and insecurities. The economic growth in the last 10-15 years has allowed us to maintain the illusion that we can borrow and spend our way to happiness.

This Independence has created some very unpleasant behaviours. Our Independent ego’s can be terribly selfish and greedy. We may criticise the bankers for their obscene bonuses, but the truth is that many of us have invested in what was a burgeoning housing market or searched out the most lucrative investment returns. I have had to eat humble pie myself as I find my savings frozen in an Icelandic bank! The reason we can act in such a greedy way is because Independence destroys empathy. With our emotions suppressed we stop feeling the consequences of our selfish behaviour and actions. We stop caring about other people and just look after number one. This is how the banking industry took such ridiculous risks – they had become blind to the consequences of their actions and in any case knew that somebody else would bail them out if it all went wrong. Of course for every winner in a commercial deal there is always a loser. Most of us would rather not think about the people who suffer. Even the plant has taken a hit - our rampant industrialisation may have made our lives more comfortable but the environment is picking up the bill.

So what does this teach us about our relationships? Independence always creates problems for us. As we separate and create an emotional distance in our relationships we stop feeling the full range of our emotions and when we do this we lose empathy. The worst thing of all is that we become blind to the people around us and their problems – we may not notice that our partner is hurting and needs our help. Instead we will make everything about us. We will look for external gratification and seek every more exciting rewards at work and in our personal life – but fail to address the growing problems in our relationships.

Ultimately though we cannot continue with such Independent behaviour forever – it catches up with us with stress and burn-out or the mid-life crisis catches up with us. In the Psychology of Vision model we reach the Dead Zone. Our relationships begin to fail and we are thrust back into our feelings of Dependence that we had defended so vigourously. The parallel in the financial and commercial world is exactly what we are seeing now. The pack of cards that is built around Independent corporations comes crashing down and we stare failure in the face. The very fear that drove us into Independence is now realised. This is the problem with an Independent strategy – it brings about the very thing that it is supposed to protect us from. In our relationships we become afraid of intimacy and the full expression of our emotions - both positive and negative. At best, we end up living half a life and cannot feel the joy and freedom that true partnership can bring. At worst we see a credit crunch in our relationships – not this time about money, but about a bankruptcy of love.

Let us hope that the current problems in the financial world are an opportunity to move to more Partnership and cooperation. Everything that happens to us both good and bad can be seen as a learning opportunity. We can re-build the banking sector as an industry that is emotionally intelligent and really cares about people. It would be in service to the people of the world rather than in competition with it. Perhaps this is somewhat idealistic give the egotistical track record of man, but at least we can choose to live in Partnership within our personal relationships. We can recognise the dangers of Independence and move towards people with open hearts. By feeling our emotions and communicating and healing our fears we can form much better, sustainable relationships, which then become a model for the people around us and for business.

Most of us are facing financial worries with the credit crunch. This article discusses the causes of these problems and compares them to our romantic relationships. By making parallels it provides us with some pointers to how we might improve our relationships.
