Analysis of Applications Principles of Barcode Technology in Product Cost Estimation and Identification

Bar codes are a technology for automatic identification which has found application in many business sectors. As we know that, bar codes have many applications; they have been mostly used in segments of the retail grocery as well as consumer goods industries. They use computers for barcode detection. A bar code has a self-contained message whose information is encoded in the geometry of its printed bars and spaces. When a bar code is read, the patterns of light and dark contained in the bars and spaces are translated into patterns of ones and zeros, which the reading computer interprets as numeric or alphanumeric data. In a simple barcode system, bar codes are read by passing a wand containing a light source and a photo-diode across the code to be read.
