So many items in the market are using barcode technology

A Barcode is created with black bars followed by white spaces So barcode is series if 1s and 0s representing numbers and letters Depending on the nature of Information black bars and white spaces will be created by the software

Need for Barcode Technology in Libraries

Check in check out and Renewal of Reading material is a time consuming and laborious process

Arranging tickets in a classified order is time tedious job

Tickets trays occupy space Reservation is a time consuming process To know the status of book

TYPES OF BARCODES

ONE DIMENSIONAL

Consists of black bars and white spaces

Requires ordinary barcode scanners

TWO DIMENSIONAL

Composed of grid of light and dark modules

Requires 2D camera

CONTENT OF A BARCODE

Information of the product will be transmitted into numeric or alphanumeric form with the help of computer software.

The content and size of the bar code will depend on the data message, symbology, dimension, and bar code height.

CONTENT OF A BARCODE

The software will convert the information into black bands and white spaces.

While printing the bar code labels the stationery and environment in which the labels will be used should be taken into consideration

Application of barcode technology for

stock verification

Data capture machine with hand held terminal Dumping data on to the computer Generation database with Accession numbers Comparison with database generated by by the

data of capture machine. The mismatch will reveal the findings of the stock

verification. This will save a lot of time and laborious process in

the stock verification. This can be completed with in few days.

Benefits of barcode applications

ACCURACY: accurate and reliable

Human operator will commit undetected error for every 300 input.

Adopting bar coding technologies will improve input by factor of 10,000 times

ECONOMICS: bar code labels can be produced in volumes,

reducing the cost for user.
