PDF417 is a stacked linear barcode format used in a variety of applications such as transport, identification cards, and inventory management. "PDF" stands for Portable Data File. The "417" signifies that each pattern in the code consists of 4 bars and spaces in a pattern that is 17 units (modules) long.
An ITF-14 bar code. The thick rectangular border is the Bearer Bar. ITF is often used for marking product ID numbers or other codes, of various lengths, on item cartons and multi-unit cases. One specific instance of this, standardized by GS1, is the ITF-14 bar code used to mark packages with Global Trade Item Numbers. In these uses, the ITF bar ...
Decoding begins at the corner with three black pixels, and proceeds clockwise to the corners with two, one, and zero black pixels. The variable pixels in the central core encode the size, so it is not necessary to mark the boundary of the code with a blank "quiet zone", although some barcode readers require one.
Code 39 (also known as Alpha39, Code 3 of 9, Code 3/9, Type 39, USS Code 39, or USD-3) is a variable length, discrete barcode symbology defined in ISO/IEC 16388:2007.. The Code 39 specification defines 43 characters, consisting of uppercase letters (A through Z), numeric digits (0 through 9) and a number of special characters (-, ., $, /, +, %, and space).
Python Bar Code 128 – This code appears to draw boxes one pixel wide. It appears it was modified from a short line long line bar code which would have drawn lines. The "Black boxes" should be the same size as the "White Boxes". GenCode128 – Free C# source code implementation of Code128. Almost all features are implemented, but is not 100% ...
GS1 introduced the barcode in 1974. [8] A barcode encodes a product identification number that can be scanned electronically, making it easier for products to be tracked, processed, and stored. Barcodes improve the efficiency, safety, speed and visibility of supply chains across physical and digital channels.
ID-000 specifies a size of 25 by 15 millimetres (1 in × 9 ⁄ 16 in), with one corner slightly (3 mm or 1 ⁄ 8 in) bevelled. The ID-000 size was first defined by ENV 1375–1, Identification card systems — Intersector integrated circuit(s) card additional formats — Part 1: ID-000 card size and physical characteristics.
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).
