What is a Barcode Symbology?
Now that you know what a barcode is, how it works and it’s benefits, you need to know how it actually shares the encoded information. Barcode symbology is the language of barcodes. Different bar and space patterns in a barcode represent different characters, sets of these patterns are grouped together to form a barcode’s symbology. It’s this symbology that enables a barcode scanner to read the information accurately from a barcode. There are many types of barcode symbologies and they all have their own special characteristics. In fact, many symbologies were created to meet the needs of a specific industry and they have symbologies that are unique and aren’t interchangeable. Now that you know what barcode symbology is, I will introduce you to the most common symbologies and their uses in my post Types of Barcode Symbologies.
