Barcode • It is an automatic identification technology. • It is predefined format of dark bars and white spaces. • Structured to contain a piece of information. • It allows real time data to be collected accurately and rapidly. • Combination of barcode technology with computer and application software improves performance, productivity and profitability.

Why Barcode? • In the early 1970 s, common barcodes started appearing on grocery shelves. • When barcodes are used in the business process, procedures are automated to increase productivity and reduce human error. • Whenever there is a need to accurately identify or track something, bar-coding should be used. For example, in a data entry work environment, workers may be required to enter an enormous amount of data into a customer database system. • Instead of manually typing a customer identification number into a database, if the information is contained in a barcode, a data entry operator may scan in it.

Barcode Types 1. Linear barcodes 2. 2 D barcodes

How it works. A Barcode is simply machine readable language. The barcode is a set of lines and spaces that represents a set of characters. These characters can be alphabetic or numeric depending on the type of barcode used. Below are some individual letters and characters.

Applications of Barcode • Hospitals • Retails • Office • Health • Travel • Libraries

Advantages • Represent unique identity of a product • Accuracy of data input • Cost efficient • Real time data collection • Labor savings by avoiding manual system

Disadvantages • System Failure may cost more delays • Scratched or crumpled barcodes may cause problems • Data must be coded in the barcode • In laser scanning, durability and cost are the two disadvantages
