Bar codes can be found on any product you buy today at supermarkets or shopping malls. Everything, from the biggest TV to a package of gum, has this unique code that distinguishes it from all other products.

The unique symbols that each barcode contains is determined by the height, width and spacing of the bars. The choice of bar used will determine the type of information contained in the code, either numeric data, alphanumeric data or character data.

Photo sensors in the bar code scanners convert the bars into electric signals which can then be “read”.

Each product gives a unique signal since each bar code is unique, and this signal is converted into readable characters by special software that accurately measures the height, width and spacing.

In a matter of seconds, the information is gathered by the software and sent on to the main computer.

The critical tool is the decoder, which is capable of accepting upwards of 250 scans per scanning rate without making a mistake. Scanners also come equipped with an automatic discrimination feature that allows the scanner to identify what type of code is being scanned.

There are many other important pieces to a bar code scanner, but what are all these pieces for?

If you look at all the items on the shelves of a grocery store, you’ll notice almost all of them have a UPC (Universal Price Code) sticker. The scanner reads the bars of the UPC and adds that to your account.

Not only that but bar codes can make compiling inventory reports much easier. Scanning products can reduce errors by clerks, either in calculating sales or recording them, as well as providing faster service to clients.

No one wants to wait in line, watching the cashier try to ring someone up manually, and scanners help everyone from a gas-and-go to departments stores tend to their customers quickly and efficiently.

All products in the market are bar coded these days. Even the smallest retail items, like chocolates or pencils, have a unique bar code to identify them accurately. Bar codes have specific symbology that is defined in the height and width of the bars as well as the spacing between them. Each of these bars might represent only numeric data, alphanumeric data or character data, depending on the type of symbology being used.

Bar code printing software is used to print bar codes on labels. They are small, convenient to use and can design labels as necessary. Although there are manually operated printers, present trends show a change in this kind of printing. Many are using software suites that guide the printer to print the labels with minimal human help. The user needs to specify the design and the software takes care of the whole printing process at a much faster rate. These software suites are accurate, and print the labels with minimal wastage in the process.

Software suites usually give additional software linking facilities so that it can link to a document or database containing the design for the label. The software would then recognize it and print it as per user instructions. All bar code printing software is compatible with popular operating systems such as Windows, Macintosh, and DOS. Also available are variations that work on operating systems such as Unix, ASP and Linux.

As is the case with all designing software suites, bar code printing software comes with some excellent sample designs. Colors, designs and fonts can be designed as per the users requirements. They would be compatible with spreadsheets, databases such as Microsoft Access, etc., and can print directly from these files or reports.

Printers normally store these fonts, which can be used as and when needed. Even newer fonts can be downloaded and stored for specific uses. One command would be sufficient for the printer to start printing the bar codes on the documents. Individuals having proficiency in software development and programming can also take help of the libraries, ActiveX controls, and other linkable procedures to create unique bar codes using graphic characters and fonts.

Bar code printing must be accurate, as an individual cannot understand the output unless the same is scanned. Before printing the bar code, the user must ensure that the font, size and other details are correct, to get an error-free set of labels.

All products are labeled with bar codes today. Even the smallest retail items, like chocolates or pencils, have a unique bar code to identify them accurately. Bar codes have specific symbology that is defined in the height and width of the bars as well as the spacing between them. Each of these bars might represent numeric data, alphanumeric data or character data, depending on the type of symbology being used by the user.

Each bar code has a start bar and an end bar to allow the scanner to read the data precisely. Some bar codes have another bar before the end bar, known as the checksum bar code. After the scanner calculates the sum, it is verified with the value of the checksum bar code for accuracy. This ensures exact calculation with minimal errors.

Bar codes help during data collection, inventory tracking, and other asset tracking. They keep accurate records of all the items scanned and so are a big help while taking care of the inventory.

Any company or manufacturer has fixed assets. These must be kept on record. All manufacturing equipment, tools, and various other assets come under the category of fixed assets. Earlier, keeping track of all these assets was done manually and workers had to put in long hours to have all the details on record.

With the advent of bar codes, even the tracking system has been made easy. All fixed assets can be bar-coded and kept track of using bar-code fixed-assets tracking software. In schools and colleges where students are provided with laptops, these are noted in the database as loaned. This also holds true for companies that provide employees with laptops and other work-related paraphernalia. Even the smallest items are tracked using bar codes. Fixed assets tracking software is a big help in such areas where a company needs to have an idea of where assets are located.

Company-related files, documents and important notes could also be considered fixed assets and noted in the database of their whereabouts. This is especially important in medical and legal fields.

Fixed assets tracking software is essential in all major companies, schools, offices, hospitals and other big places where one person keeping track of all the assets is an impossibility. Bar code tracking software can be of immense help in such areas, and would ease problems related to records.

With all the facilities and extra utilities provided by the bar code software suites, they are expensive. Not everyone can afford to buy this software. Small-scale manufacturers and retailers would have a tough time investing in the bar code printing software if their budget is limited.

Available online are free bar code software programs that can either be downloaded or used online to design a bar code. This design can later be saved onto the computer and printed as required. The user needs to log in to the website and provide basic details relating to the bar code, such as the bar code symbology, height of the bar code, resolution, density of the bar code, and output format. Most of the websites are user-friendly, and the application for the bar code is extremely simple to understand.

Some websites allow the customer to provide details in depth, such as if they would like the checksum facility. This is for customers who have in-depth knowledge of they need. Otherwise the customers can just ask the website to generate a bar code that can be saved onto their computer and used at a later stage. Since the websites are free, customers can log in at any time and request a bar code generation. The whole process would take not more than five minutes, and is very simple and easy to understand and use.
