The barcode language is actually quite simple. All barcodes contain specific symbols which equal a series of bars. These bars are made up of short and long bars, along with varying spacing between the bars. Every part of the series denotes a number of characters, depending upon the date originally entered into the barcode software.

In other words, barcode software is the beginning point for all barcodes and barcode scanning systems. It is what makes the system work. Programmer are able to use barcode software to inventory their products by inputting the product’s name and assigning it a barcode generated by the computer.

This is all accomplished by using a sophisticated database system, where data from each product is stored. This makes keeping track of the inventory easy and it also helps to speed up the updating of pricing. New information about products is entered into the database. Then whenever the barcode scanner reads a barcode that identifies a specific product it is connected directly to the database where it finds the most current information about the product.

The barcode scanner itself uses technology that “reads” the barcode label. It does this with photo sensors located within the barcode scanner that have the ability to read and decipher each barcode as it is scanned. All of these photo sensors work together to recognize spacing, length, and alignment of different bars, then match them with corresponding product information found in the database. This ingenious technology is really quite simple when you understand how it works.
