What Is Barcode Symbology? Size of Barcodes.

A barcode is an optical, machine-readable representation of data. Barcode symbology is the method of encoding data with dots, spaced lines, or squares. 

Once those barcode symbols are scanned by a barcode scanner, they are decoded, recorded, and analyzed to extract data for various applications.

When inspecting a barcode, you may find that some appear different from others.

In fact, there are two types of bar code symbology: discrete and continuous.

Discrete barcode symbology

The discrete type of symbology merely means that each character on the barcode may be decoded independently without relying on the other characters on the same barcode.

In other words, the scanner or equivalent gadget decodes each individual character.

Continuous barcode symbology

On the other hand, continuous barcode symbology requires that every character on a single barcode be read together.
