The basic types of barcode cards

The barcode card is divided into one-dimensional barcode and two-dimensional barcode. The one-dimensional barcode carries a limited amount of information, such as the barcode on the commodity can only accommodate 13-digit (EAN-13 code) Arabic numerals, and more information can only rely on the support of the commodity database, leaving the pre-established database, this barcode is meaningless, therefore, to a certain extent, it also limits the application scope of barcode. For this reason, ah invented two-dimensional barcodes in the 1990s. In addition to the advantages of one-dimensional barcodes, two-dimensional barcodes also have the advantages of large amount of information, high reliability, confidentiality and anti-counterfeiting. From the day it was born, it has received widespread attention from the international community.

Three-nine code.

The Sanjiu code is a non-continuous type of coding in which both bars and blanks represent information. It can represent 44 characters such as numbers 0-9, letters A-Z and eight control characters (-, space,,, $, +, %, -,) and is mainly used in industry, books and the automated management of tickets.

Codebar codes.

Codebar (Codebar) code is a kind of barcode with non-continuous, variable length, bi-directional self-test that both bars and spaces represent information, which can represent numbers 0-9, letters A-D and special characters (+, -, $, :, -).

Crossed two or five codes

The crossed two-five code is the same as the two-five code, except that the interval between the barcode and the information is used as part of the preparation of a continuous code.
