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

A barcode is an optical machine-readable representation of data relating to the object to which it is attached. Originally barcodes systematically represented data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangles, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanne ....etc
