Wireless Barcode Scanners
There are more than 400 international barcode brands currently in use today. When influential the right symbology for your business, it is best to use a universal influential supported by most manufacturers. The other factors to consider are the type and amount of data to be encoded and the cost of the associated scanning and printing equipment.
Generally, each character in a bar code is represented by a series of bars and spaces. The code includes a quiet zone, start code, data, stop code and trailing quiet zone. Some codes support check digits to ensure data integrity. The check digits are usually located before the stop code.
The compactness of a barcode is defined by the narrowest element (in this case width when displayed horizontally) of the barcode. There are three standard densities or resolutions:
• High density/resolution - less than.009 inches (.23mm)
• Medium density/resolution - between.009 inches (.23mm) and.020 inches (.50mm)
• Low density/resolution - greater than.020 inches (.50mm)
For the most effective scanning, despite of the type of input device, you should use the lowest density possible that will print on the area available on your application. In a nutshell, the lower the density, the larger the graphic and a larger depth of field for the scanner to recognize the symbols.
The low density symbols can be printed on any dot matrix, inkjet or laser printer thus reducing the cost of high density printing and scanning equipment. As we said earlier, the key to selection is the space available on the your application, e.g. shipping labels, price tags, etc. Many buyers purchase high cost printing equipment when their standard office printer will suffice.
The symbologies are defined by four criteria:
• Character Set - alphanumeric or numeric
• Number of ASCII Characters - the standard symbologies range from 10 to 128
• Maximum Characters per inch - the standard symbologies range from 9.4 to 24.2
• Variable Length - barcodes are either variable length or not.
The above is only intended as an preliminary primer to the barcode technologies. The objective is to provide a growing knowledge base for businesses to use in making purchase decisions. The uninformed will pay more for equipment and systems they do not need.
The next articles in this series will continue to describe and inform on barcode technologies. Specifically, the next article will be on the nine symbologies most accepted by the international industrial community.

Wireless Barcode Scanner - The History of Barcode Scanner
Wireless Barcode Scanner
A laser barcode scanner is the most ordinary type of barcode scanner. They are generally easy to use and do not have to be in real close nearness to a barcode in order to read the barcode.
The idea of the modern barcode can be traced back to 1948 when a graduate student at Drexel Institute in Philadelphia approached a teacher and told him about a conversation regarding a way to quickly and accurately capture product data at the check out counter. The idea intrigued the teacher and he worked on a product for the next two years and finally invented the first barcode by using Morse code.
The student and the teacher applied for a patent. IBM wanted to develop the technology but the teacher and student held out for a price that more closely reflected the potential of the technology and sold the patent to Philco in the early 1960s, and Philco went on to sell the patent to RCA.
Other companies were just beginning systems as well, knowing that the grocery business, in particular, would benefit from an easier way to keep track of items sold and when to re-order items. It was not until 1974 that the first product was actually logged in using a barcode system - the product was a 10 pack of Wrigley's chewing gum.
Next came industrial companies wanting to use a barcode system and then libraries got into the act. Throughout the 1970s became affordable and practical. The use of laser barcode scanners made the entire process much easier.
There are many laser barcode scanners to choose from and manufacturers include Wasp, Motorola, Honeywell and DataLogic to name a few. These scanners can read a barcode from about six inches all the way up to about thirty feet depending on the scanner you wish to purchase. A laser barcode scanner can cost as little as one hundred fifty dollars and as much as two thousand dollars.
The Honeywell 4820 scanner is great for light industrial mobile barcode reading applications. It features Bluetooth v1.2 radio wireless communications for freedom of movement in retail, warehouse and distribution. It offers movement of up to thirty-three feet from the base. This laser barcode scanner is priced at just about six hundred dollars.
The Wasp WLS9500 series laser barcode scanner is a high performance scanner. It is ideal for healthcare, retail and warehouse use. It will even read damaged or scantily printed barcodes and can scan barcodes up to poorly thirty feet away. It is designed to withstand constant, rigorous use in office to warehouse environments. It is priced at just around three hundred dollars.
The Motorola Symbol LS2280 laser barcode scanner is unimportant but will give you maximum productivity. It will work from near contact to approximately seventeen inches away. It is ideal for hospitals, retail stores, education and government settings. It is very strong and offers a scratch resistant tempered glass exit window. It is priced at approximately one hundred sixty dollars.
These are only three examples of many great laser barcode scanners that are available. You can often find great deals online and it is also very easy to do a comparison of quality to ensure that you are purchasing the barcode scanner that will meet all of your needs.
