David Key of California: The Effects of Fax Transmission on Bar Code Decoding

David Key, Irvine CA, the bar coding technology expert explains about the effects of Fax transmission on bar code decoding, he says as per the faxed documents of bar coding symbols, it has been ascertained that the quality of bar code symbols have been degraded. All the documents are scanned by the fax machines in accord to the standard resolution sampled as per 98 vertical dots per inch and 204 horizontal dots per inch.

Afterwards, each and every sample point is translated into a black or white value, a procedure known as binarization. According to this process, the straight lines of the bar code symbols are converted into ragged ones, altering the width of spaces and bars. Every additional fax cycle extends to delineate the quality of a bar code. In fact, at a certain point, the symbol is not able to get decoded by the bar code decoding software.

David Key, Irvine CA tells two symbologies in order to explain Effects of Fax Transmission:-

1. (1D) Linear symbologies – Two most popular linear symbologies were analyzed and tested – Code 39 and Code 128. Code 39 uses two bar and space widths to convert the information whereas Code 128 uses four. Afterwards, thirteen most belittled module sizes varying from 12.5 to 32.5 mil of every symbol form were encoded and printed on a sheet. The sheet was beamed and sent via fax at standard resolution for ten cycles. The resulting eleven pages were scanned via scanner at approx. 300 samples per inch and were represented to a bar code decode software. Both bar code symbologies were able to successfully decode for 3 faxes at 2.6 samples per module, whereas the same codes having 6.6 samples per module were able to read even after 10 faxes. There is one thing to consider i.e. the greater the size of the module of linear code is, the more horizontal it will be to encode the same amount of data, but the larger module sizes can improvise the read rate.

2. (2D) Matrix symbologies – This process renders better information about the accuracy and density as the information gets encoded in both vertical as well as horizontal directions. The data matrix used was a 12*12 module square symbol, and 2D symbols can be printed with much greater size module symbols, as compared to linear symbols encoding the same information.

In a nutshell, if the documents comprising varied bar code symbols are faxed multiple numbers of times, then the bar code symbols get printed with a greater sized module to be successfully decoded.

David Key of California Reveals QR Codes: What is Behind All Those Dots?

David Key of Irvine Calfornia, has specialized in bar code technology since he graduated from college. Back then the latest technology was bar code 39 which is still an industry standard in many applications. Key explains that the new bar code today is QR Code which is an optical representation of data that can be read easily by the scanning device instrumentation and mobile devices, which in turn gets translated by the special software. Prior to QR Code, bar codes were available as specified parallel lines usually in black color, known vastly as one-dimensional or linear bar codes. Though, in these days, bar coding devices are able to read all kinds of patterns including hexagon, square, dots and other geometric patterns, known widely as two dimensional matrix codes. All such symbols are not bars, but still referred and pertained as bar codes. The new applications for QR Codes are endless due to their wide variety of applications in today’s mobile and Intenet markets. David Key specializes in QR Code applications in today’s commercial and retail enviroments. The QR Code in the upper left can be scanned with any smart phone and it so happens to take you to this article!

Everyday mobile devices can now scan QR Codes

Today QR coding is being employed and used in retail sectors, to automate their checkout procedure and point of sales system in addition to consumer habits and service usage. Since then, bar code systems are vastly used all over the world in several other industries and applications. Moreover, varied forms of bar codes as well as bar scanning devices are available in the market nowadays at affordable prices. There are distinctive components including QR bar code readers and optical scanners that read the codes scanned from an image integrating special software to interpret, which is very similar to the software employed in Smart phone platforms. In addition, other bar code equipment constituents includes screen displays, CPU’s (Central Processing Units) and bar code printers, which are very flexible and compact to get fitted in any space or location.

The most appealing and acknowledged component of bar coding system involves a bar code scanner, which you have for sure ascertained as a red light that seems to appear every time a bar code is scanned. Comprising no as such moving elements, bar code scanners are used as hand held devices and permanent fixed bar code instrumentations. Becoming an indispensable part of our daily lives, bar coding systems can even scan damaged or low quality bar codes with utmost accuracy and preciseness. All the components of bar coding system were especially designed as light weighted, compact and mobile, considering space management purposes in mind. In short, bar coding equipment’s and bar coding scanners have changed the entire world procedure, leading it towards more accurate and speedy transactions, saving a lot of time of people.

What’s amazing is that today’s QR Codes can be seen on T-shirts, retail store windows, even baseball gloves at a sporting goods store. You name it, a QR Code is probably attached to it. Today’s smart phones can easily scan a QR Code to see how much the product costs to searching for a better price at other stores. But using the QR Codes to test and monitor buying behaviors is the latest crave for this high tech square of dots known as QR Codes.

Advantages of Barcoding Technology – David Key of California

Upon graduating from College, David was hired as a national sales rep for a third party barcode technology company (ICC). Here are some reasons barcode is this industrty continues to thrive:

1. Barcoding process lowers labor costs as well as optimum time. Eliminating the need for manual labor, helps with efficiency and accuracy. It’s an incredible tool for tracking products and even services.

2. The collection of data and information is much fast. A scanner can record the type of data approx. 7 times quicker as compared to a skilled and proficient typist working manually. The accuracy and precision gets improvised up to 10,000 times better with the help of a scanner.

3. Availability of an easy and rapid access to information and other details about inventory, products and services. Along with keeping a full control and hold on inventory management system, it assists in prompt decisive making. Real time data can make the difference in millions of dollars for companies regardless of their products.

More Uses of barcode Technology

1. One of the most common applications is the point of sale, where the products we buy as users gets scanned at the cash point. It really saves time and as a result it’s help keep the cost of products down.

2. Can be used for production organizations and firms to keep a track of the different stages of work being completed on a project, barcodes aid in keeping detailed and thorough information about each and every step of the manufacturing procedure.

3. Scanning process fully controls and ascertains the inventory management. At regular intervals of time, data can be uploaded from a hand-held scanner to company’s system, lowering your time as well as effort.

4. Today it’s also used for security practices; barcodes provide an easy access to the employees to their destined and intended work arenas.

5. In the packaging and warehouse environments, barcode printers plays a vital role by providing assistance in identifying parts and numbers for shipping products.

6. Medical and dental clinics make use barcodes as a means to keep patient records sieved more easily and conveniently.

In short, David Key of Irvine Orange County/ pointed that the origination of barcodes has changed the way firms handle time and money in a more cost effective manner.
