Introduction :The Rapid development in information technology has brought out a revolutationary change in the field of library system and services.The new information technology has changed the manual scenario of library to computerized automated libraryThe RFID technology is a latest technology for automatic identification method.
What is RFID systemRFID is an acronym for Radio Frequency Identification. Briefly the RF stand for “radio-frequency” and ID means “identifier” that allows an item, for instance a library book, to be identified, accessed, stored, reprogrammed and communicated by using radio waves
History of RFID : In 1946 Leon Theremin Invented an espionage tool for the soviet Union which retransmitted incident radio waves with audio Information The RFID first used in World War –II differentiate between friendly enemy aircraft
RFID IN LIBRARIES The concept of RFID can be simplified to that of an electronic barcode and can be used to identify track short or detect library holdings at the circulation desk and in the daily stock maintenance. This system consisting of short RFID labels , hardware ,software provides library more effective way of managing their collection while providing grater customer services to their patrons.
RFID Architecture Backend Database Firstly items-tag are scanned by reader; Secondly in backend transmitted data coming through antenna (RF-wave) are being recognized by Tags Reader Application RFID-based system PC. It acts as a middleware Gateway communication gateway among items, reader and system database; Scanned And at the end it filters out and store data in RFID- Database databases for checking the data fault and relevant User operation. Interface Fig.2. A General Overview of RFID Architecture
Key Components READER SELF CHECK- OUT/IN INVENTORY READER BOOK DROP READER MIDDLEWARE (PC) SECURITY GATE LABEL PRINTER
READERHandle reader is basically using for shelf order checking shelf reading searching inventory scanning in the library kind of environment .
SELF CHECK-OUT/IN Self check-In/Self Check-Out primarily for self issue and return of books in library . With its inbuilt screen & printer ,patrons can view& printer transaction related information such as number of books issued ,out standing , fine etc. Customized information can also be printed on the transaction slip.
INVENTORY READER Reader play multiprotocal antenna reader for circulation desk application
BOOK DROP READER The drop box used for returningthe books It helps better circulation & gives timeFlexibility to patrons for returning of library materials issued by them
SECURITY GATE The gate detection System capable of detecting un authorized tagging items passing through it. It has inbuilt audio visual alert facility for theft detection and minimum read range of 36 inches.
Passive Tag RFID passive H F tag working on 13.56 MHZ Frequency . The tags available various types and forms factors these are used for tagging library materials to uniquely identify particular tagged items using the RFID base automated library management system Cost : Rs. 10 - 30
Active Tags : Active tags are able to transmit data using their own battery power. Read ranges are more for active tags than for passive tags but are costlier for their extra capability. Therefore active tags are used for high value items and for longer reading distance.
Standards : RFID STANDARD USED FOR LIBRARY: Standard : ISO-15693 Frequency: 13.56 MHZ Dimension : 400mm X 200mm X 120mm Housing : Metal Data Interface: RS 232 Protocol : SIP and/or API (presently using STX/ETX communication protocol) Indicator : Tag Data LED and Power LED Voltage : 230 Volt Certification : CE and Radio Approval
Who are the users of RFID Most Installations are found in America & European libraries .In India : Pune university Library I I T Madras Library , Chennai NIT Silchar Library , Assam Punjabi university Library , Chandighar S R M University Chennai
Campus Management RFID technology can fully automate various transactions happening within a Campus. Students, teachers and staff can be provided with RFID smart cards for their attendance and access to various labs and library. Library systems can also be automated by using RFID which can include issuing of books, security gates, searching of books, etc. Assets like computers, electronic equipment and mechanical tools which are constantly on the go for student experiments can be tracked to improve their usage by various departments. Hostel can also be better managed with access control system installed for students.
Advantages / Benefits Implementing RFID will considerably reduce the amount of time required to issue , receive ,transport ,sort & shelving library material Library staff is alerted immediately un authorized issues of books The RFID book drop system provides provision to return books during off hours of the library Tag cost decreasing of day by day
Disadvantages The cost of involved for initially investment and recurring expenditure for tagging , maintenance is very high More chances for Physically damage /tearing of tags There is possibility to return damaged books in drop box
Conclusion : The RFID Technology is more popular latest technology in India with more development in coming days in academic libraries and different sectorswww.rfid-library.com/en/system-flash-demo.html
