The emergence of technology in transport, communications, computing and entertainment has long been observed by the population. And with the development of these technologies implemented inventions, the need for safety and security. The technology has also seen the need, the development of bar codes and tags.A barcode is a representation of information. E 'can be read by a computer called a scanner. This is a small piece of paper covered keywords. Bar codes are dark ink, usually with a white background.This happens to think up and down on the scanner allows you to code in binary language. In this way, the scanner code. In the past, the bar code on the premises of parallel lines.

Bar codes for transmission of information and transmission depends on how the local bar and a code.Barcode scanners, and digitizing the information, that these binaries in the transmission of voice, then the computer is. With the light sensor with the scanner, the amount of reflection, then an analog model. Several types of machines to read or the scanner is designed for more efficient and more precise. These scanners are available in a variety of sizes, shapes and prices. Body scanners are more commonly used.Many supermarkets. Light Pen is also one of the most commonly used, since it is portable and inexpensive. Another is the nature of the bar code-Slot Reader is used to move the scan codes.

This is because, less effective, less costly and less effective than manual work.
