Types of Barcodes and What They Do


1D Barcodes

A one-dimensional, 1D (linear) barcode is the most commonly used type of barcode today, with all the information in the code organized horizontally from left to right. While simple in structure, there are several versions, with some able to encode only numbers while others can encode any keyboard character. Depending on the specific type of 1D barcode used, you can encode between 20-25 characters. A barcode scanner is required to read 1D barcodes.
