HOW DOES A BARCODE WORK?
Each character is represented by a pattern of wide and narrow bars. A barcode reader uses a photosensor to convert the barcode into an electrical signal as it moves across a barcode. The scanner then measures the relative widths of the bars and spaces, translates the different patterns back into regular characters, and sends them on to a computer or portable terminal.
Every barcode begins with a special start character and ends with a special stop character. These codes help the reader detect the barcode and figure out whether it is being scanned forward or backward.
A checksum is calculated when the barcode is printed using the characters in the barcode. The reader performs the same calculation and compares its answer to the checksum it read at the end of the barcode. If the two don't match, the reader assumes that something is wrong, throws out the data, and tries again.
There are different barcode symbologies, each with its own particular pattern of bars. The UPC code used on retail products is an all-numeric code; so is the Interleaved 2 of 5 Code. Code 39 includes upper case letters, digits, and a few symbols. Code 128 includes every printable and unprintable ASCII character code.

And once you've chosen the printer that's right for you, you can customise it with a variety of useful options. Add a verifier and practically any label stock you can imagine, and you've got a bar coding system that will serve you well for years to come.
Barcode software is a relatively recent development, yet barcodes are now such a familiar part of everyday life that it is almost difficult to remember a time without them. Today, almost every product you buy, almost every package you receive, has a barcode—whether it’s a familiar one-dimensional (1D) barcode with alternating black and white bars, or a more recent two-dimensional (2D) barcodes such as a QR code.
Barcode labeling has obvious advantages in a business setting: It increases efficiency, reduces costs and errors, and helps meet regulatory requirements. But these benefits are only achieved if the barcode software used to create those barcodes can be trusted to encode the required information quickly and correctly and print it consistently and accurately. It’s not enough to use an online barcode generator.
We can supply a number of barcode software solutions. BarTender by Seagull is an easy to use entry level soware package.
