When using Library Management system, each barcode image is programmed to identify the title of book, author name, item number, volume number etc. All this information is shown in one barcode with the help of coding. Now a day’s libraries need new tools that will allow them to increase their productivity and improve user service without adding personnel. Application of Barcode technology in libraries is a way to process client requests from fast to fastest. Barcode technology is mostly used in the circulation system of a library and most successful due to its speed, accuracy, minimising human error to almost zero label and reliability. Barcode technology provides a simple and in expensive method of encoding text information that is easily read by in expensive electronic readers. Barcoding also allows data to be collected rapidly and with extreme accuracy. Barcode technology is to improve library procedures by increasing the efficiency of library transactions, reducing work loads of the library staffs, and improving services for library users.
