What is 2D barcode (two-dimensional barcode)? – Definition from WhatIs.com

A 2D (two-dimensional) barcode is a graphical image that stores information both horizontally — as one-dimensional bar codes do — and vertically. As a result of that construction, 2D codes can store up to 7,089 characters, significantly greater storage than is possible with the 20-character capacity of a unidimensional barcode.
