1 Types of barcodes
The international article number IAN, also known as the European Article Number EAN, which technically refers to EAN-13.
The Universal Product Code UPC, is a bar code symbology (that is, a specific type of bar code) that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, and other countries for tracking commercial items in stores.
Code 39 is a barcode capable of representing capital letters, numbers and some special characters, such as space.
|interleaved 2 of 5||
Interleave 2 of 5 ITF, is a two-width continuum of the digit code symbology barcode.
PDF417 is a linear stacking barcode symbol format that is used in a variety of applications, primarily transportation, identification cards and inventory management.
A QR code (Quick Response code) is a module for storing information in a dot matrix or in a two-dimensional barcode.
The Serial Shipping Container Code (SSCC) is an 18-digit number that is used to identify logistics units.
UCC / EAN-128 uses normal Code 128 barcodes, but formats the data in a standardized manner to identify the type of information contained in the barcode.
Smart barcode mail (IM barcode) is a 65-bar barcode for use in mail in the United States. The term "Intelligent Mail" refers to the services offered by the United States Postal Service for the delivery of internal mail.
UCC/EAN-128 uses normal Code 128 barcodes, but formats the data in a standardized manner to identify the type of information contained in the barcode.
The Universal Product Code (UPC) is a bar code symbology (that is, a specific type of bar code) that is widely used in the United States, Canada, United Kingdom, Australia, New Zealand, and other countries for tracking commercial items in stores.
The Bookland EAN barcode is used internationally to identify books, as well as video and audio tapes and software.
Standard 2 of 5 is a low density numerical symbology that has been with us since the 1960s. It has been used in the photo finishing and sorting industries, as well as air tickets sequential numbering.
Code 39 is a barcode capable of representing capital letters, numbers and some special characters, such as space. Possibly, the most serious drawback of this code is its low information density because more space is required to encode data in Code 39 than, for example, in Code 128.
Code 39 (also known as Alpha39, Code 3 of 9, Code 3/9, Type 39, Code 39 USS, or USD-3) is a variable length, discrete bar code symbology. The specification defines 43 characters, consisting of uppercase letters (A to Z), numeric digits (0 to 9) and a series of special characters (-,., $, /, +,%, And in space). An additional character (denoted "*") is used both to start and stop delimiters. Each character is composed of nine elements: five bars and four spaces. Three of the nine elements in each character are wide (binary value 1), and six elements are narrow (binary value 0). The ratio between narrow and wide width is not critical, and can be chosen between 1: 2 and 1: 3.
Codabar is a linear bar code symbology developed in 1972 by Pitney Bowes Corp. (). And its variants are also known as Codeabar, Ames Code, NW-7, Monarch, Code 2 of 7, Streamlined Codabar, ANSI / AIM BC3-1995 or USD-4.
From the Codebar family.
One of the binary level barcodes, developed at the relatively early stage of Monarch Marking Inc., in 1972. Name it by its composition of two types of bars, N arrow and W ide, and make a figure with seven black/white bars of them. Generally called CODABAR
From the Codebar family.
The POSTNET and PLANET barcodes are used by the United States Postal Service. POSTNET barcodes have a variable length of 32 to 62 bars, and the PLANET is 62 or 72 bars. They are modulated in height (vertical bars are different lengths) and 2-state (there are two different types of bars, low and high). Each digit of coded data is represented by a group of five bars. POSTNET barcodes have exactly two height bars in each group of five, while the PLANET barcodes have three.
