What is a 2D barcode? A 2D (two-dimensional) barcode is a graphical image that stores information horizontally as one-dimensional barcodes do, as well as vertically. As a result, the storage capacity for 2D barcodes is much higher than 1D codes.

2D codes come in two types: stack and matrix. The selection of which type to use depends on factors such as the amount of information to manage, the marking area, and the reading method. This page introduces the characteristics of these two types of 2D codes.

Two-dimensional barcodes, known as 2D codes, store information both horizontally and vertically. This allows them to hold more data compared to traditional linear barcodes or “1D codes,” which are the typical barcodes found on retail products, comprised of black and white stripes. 2D codes can contain up to 3000 characters, while 1D ...

Mar 11, 2025 · 2D barcodes are a more advanced type of barcode that stores data both horizontally and vertically. This two-dimensional structure allows 2D barcodes to hold much more information without increasing in size. They can be scanned from any direction using imaging scanners or smartphone cameras.

This page provides an overview of 2D codes such as QR codes and DataMatrix. The “Barcode Information & Tips” site offers information on the standards, basic principles, and reading know-how related to barcodes and 2D codes.

Finder Pattern: 90° “L” shape pattern that makes up (2) sides of the code. This is used by the camera to locate the code and can be marked as a solid or dotted line. Encrypted Code: This is the body of the UID/Matrix2d and contains all of the information.

2D barcodes are divided into matrix codes, such as QR, Data Matrix, Aztec, Code One, as well as dot codes, such as Dot Code A and stacked codes, such as PDF 417, Coda Block and Code 16K.

Jan 12, 2025 · What is a 2DBarcode? A 2D Bar code is a two-dimensional way to represent information. The history of QR codes shows how 2D barcodes were created to address the limitations of plain 1D barcodes. It is similar to a linear 1D …

Two-dimensional (2D) barcodes are a type of barcode that encode data in both horizontal and vertical dimensions, allowing for a greater amount of information to be stored compared to traditional one-dimensional (1D) barcodes.

2D stands for two-dimensional and a 2D barcode contains information in both the horizontal and the vertical, unlike traditional barcodes which are vertical black and white lines and contain a lot less data. A 2D barcode also physically looks different compared to …
