Barcode

used to identify articles, loading aids, storage locations and other objects. The barcode consists of a series of bars and spaces of different widths that can be read by a barcode reader such as a scanner.

There are different types of barcodes, including numeric codes such as the 2-out-of-5 code and alphanumeric codes such as Code 128 or Code 39. The coding is done by varying the width of the bars and spaces. There are one-dimensional barcodes, which use only one line, and two-dimensional barcodes, which have several lines or a matrix structure.

One of the most common coding systems is the EAN system (European Article Numbering), which is used to identify products. The EAN system includes codes such as EAN and EAN 128, which contain information about the article, manufacturer and other details.

Different types of two-dimensional barcodes include stacked barcodes such as PDF417 and matrix codes such as Datamatrix. These allow a larger amount of data to be stored in a smaller space and are used in areas such as logistics, retail, medical labeling and more.

Barcodes play an essential role in automating processes and improving efficiency in various industries by speeding up data capture and reducing errors.
