There has been a lot of innovation in technology related to transportation, entertainment, communication and computer in the present times. With all this development and high technology developments there is an increasing need for better security and safety.  This requirement has also been noticed by technology and this has resulted in the development of scanners and barcode tags.

A barcode basically represents information which can be read by the device known as the scanner. Typically the barcode can be seen printed on a paper piece known as the tags. Most often dark ink is used for printing the barcodes on a white background. The reason behind it is have a high and low reflectance which allows the scanner to translate the code into binary language. It makes it easier for the scanner to read the code. Earlier barcodes were only made in regions of paralleled lines but with the development of technology, it has become possible to store all the data in various patterns and shapes.

Barcodes have started playing a significant role in our life and are being used in business fields as different as telecommunication and transportation. Businessmen are finding barcodes as a very cost-effective way of management and business.

Barcode with the scanning system make use of different symbols to convert the bar codes into a language which the computer can read which in turn makes it possible for the scanners to be able to read the code. There are some well known symbols like code 39 which presently is used for data security. It is a very effective method of securing data as it comes with a self-checking ability. When 70 million characters are scanned, it has shown just one error. Another common symbol is the UPC, which is commonly seen in non-food goods which are available in the stores. This allows more competent and simpler price look up without requiring any increase in the cost of printing. 2of 5 Code has also been developed for handling warehouse inventory and airline ticketing.

As different symbols for barcodes developed there was development in the scanners or the barcode readers. The information which is transmitted by the barcodes is based on the spaces and bars arranged in the code. It is the responsibility of the barcode scanners to scan and read the information and then convert it into the binary language for the computer to be able to read it. Various kinds of scanners and readable machines have been designed to make scanning more accurate and efficient.
