1.1. What is Barcode ?

A barcode is an optical machine-readable representation of data, which shows certain data on certain products. Originally, barcodes represented data in the widths (lines) and the spacings of parallel lines, and may be referred to as linear or 1D (1 dimensional) barcodes or symbologies. They also come in patterns of squares, dots, hexagons and other geometric patterns within images termed 2D (2 dimensional) matrix codes or symbologies. Although 2D systems use symbols other than bars, th ....etc

Abstract

The microcontroller based Barcode Decoder decodes code 39 .Code 39 was first barcode symbology to encode alphanumeric data strings .It is for this many industrial groups accepted this technology for their labeling requirements .It is widely used as standard for their labeling requirements .It is widely used in variety of applications. Hewlet- Packard's industrial Digital slot Reader is used here.

HP Barcode decoders provide an excellent scanning performance on a wide range of bar-coded cards and badges .When a bar coded card is s ....etc

ABSTRACT
A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port. The hand-held laser scanner does not have to be cl ....etc
