Example of Industrial 2 of 5 barcode. Industrial 2 of 5. [1] (also known as Standard 2 of 5 [2] [3] [4]) is a variable length, discrete, two width symbology. Industrial 2 of 5 is a subset of two-out-of-five codes. [5] Industrial 2 of 5 is one of the first 1D and oldest barcodes and can encode only digits (0-9).
The Cascading Style Sheets (CSS) specification describes how elements of web pages are displayed by graphical browsers. Section 4 of the CSS1 specification defines a "formatting model" that gives block-level elements—such as p and blockquote—a width and height, and three levels of boxes surrounding it: padding, borders, and margins.

Main finder pattern is used to detect the barcode on image and its corruption can make barcode unrecognizable. Finder pattern has vertical and horizontal size 1-1-3-1-1. Finder sub pattern helps to detect bottom-right corner of the barcode. Finder sub pattern does not have guard zone and has vertical and horizontal size 1-1-1-1-1.
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines.
A UPC barcode. The Universal Product Code (UPC or UPC code) is a barcode symbology that is used worldwide for tracking trade items in stores.. The chosen symbology has bars (or spaces) of exactly 1, 2, 3, or 4 units wide each; each decimal digit to be encoded consists of two bars and two spaces chosen to have a total width of 7 units, in both an "even" and an "odd" parity form, which enables ...

MicroPDF417 barcode was patented in 1996, [1] by Frederick Schuessler, Kevin Hunter, Sundeep Kumar and Cary Chu from Symbol Technologies company. MicroPDF417 is an extension of PDF417 barcode [6] and uses the same principles of data encoding. [2] Before 2006, the standard can be obtained only from AIM store [7] as ITS MicroPDF417 standard. [8]
