2D barcode

Two-dimensional barcode based on a flat set of rows of encrypted data in the form of bars and spaces, normally in a rectangular or square pattern.

A 2D barcode, also known as a QR code (Quick Response code), is a two-dimensional matrix barcode that can store more information than traditional linear barcodes. Unlike linear barcodes that can only store a limited amount of data in a single dimension, 2D barcodes can store information in two dimensions, allowing for a much larger amount of data to be stored in a compact format. This makes them ideal for use in applications where space is limited, such as product labeling, event tickets, and mobile payments.

A 2D barcode consists of black and white squares arranged in a specific pattern that can be read by a barcode scanner or a smartphone camera equipped with a barcode-reading app. When scanned, the barcode provides information that is encoded in the pattern of the squares. This information can include URLs, text, and other types of data that can be quickly and easily read and processed by the scanning device.
