A barcode is a graphic identifier used to express information by arranging multiple black bars and blanks with different widths according to certain coding rules. Barcodes are the machine-readable code used in trading to identify the products in the world of retail. At present, barcodes include one-dimensional barcodes and two-dimensional codes.

However, since these barcodes are one-dimensional, information is only recorded in the horizontal direction, while the height of the bar does not store information. Therefore, the information storage capacity of the one-dimensional codes is limited.

There are two types of two-dimensional codes: matrix type and stack type, which record infoermation in both horizontal and vertical directions. Therefore, compared with one-dimensional barcodes, the data storage of two-dimensional barcodes are larger, the occupied space is smaller, and the reliability is relatively stronger. At present, the application of two-dimensional code is becoming more and more extensive.
