BARCODE

Graphic information in the form of a sequence of lines varying in thickness and (or) rectangular geometric figures. This information is intended to be read by special devices. A barcode may have security features (UV luminescence, magnetic ink, etc.).

Depending on the encoding method, the following types of barcodes are distinguished:

※a linear barcode is encoded and read in one direction;

※a two-dimensional barcode is encoded and read not only horizontally but also vertically.
