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.
