What is a 2D barcode?

A single 2D barcode can hold a significant amount of information and may remain legible even when printed at a small size or etched onto a product. 2D barcodes are used in a wide range of industries, from manufacturing and warehousing to logistics and healthcare.

What is a 1D or linear barcode?

A 1D or linear barcode is a series of parallel lines and spaces of various widths. A 2D symbol is not technically a “barcode” since it is not consistent with the 1D barcode description; it is therefore more accurately called a “symbol” or a “matrix symbol” rather than a “barcode”.

What are the requirements for 1D barcodes?

Quiet Zone 1D barcodes must have a blank space of a certain, minimum size leading and trailing the barcode.

What are the different types of barcodes?

There are two general classes of barcodes: one-dimensional (1D or linear) and two-dimensional (2D). They are used in different types of applications, and in some cases are scanned using different types of technology.

What is industrial 2 of 5 barcode?

Industrial 2 of 5 is a very simple symbol in that all information is encoded in the width of the bars. The spaces in the barcode exist only to separate the bars themselves. A typical Industrial 2 of 5 barcode looks like this: Where is it used?

What is the size of a matrix barcode?

Data Matrix barcodes are adaptable in size. The symbol size can be as small as 2.5mm, which is the smallest among all 2D barcodes. Meanwhile, the size and the encoded data capacity is independent. This allows the choosing of a lot of different matrix sizes.

How many rows are in a PDF417 barcode?

Each PDF417 barcode consists of three to 90 rows, and a single row is essentially the equivalent of a small 1D barcode. PDF417 specifies that each pattern in the code consists of four bars and spaces, and each pattern is to be 17 units long.
