GOPAL BHARGAV VINAY KUMAR • Introduction • RFID Tag and Reader • Working of RFID • RFID in campus Lecture Wise Attendance Management Library Transaction Management Human Tracking System • Advantages and Disadvantages • what to expect? • Conclusion RFID … Is an automatic way to collect information or data on: Products Places Times Transactions Is identification performed in milliseconds: No line of sight required Contactless Works in a harsh environment No human error involved RFID COMPONENTS RFID TAG RFID READER RFID TAG The RFID tag is a microchip combined with an antenna in a compact package. Data is transmitted from, or written to the tag or label when it is exposed to radio waves of the correct frequency and with the correct communications protocols. RFID tags do not contain onboard intelligence TYPES OF RFID TAGS PASSIVE RFID TAGS ACTIVE RFID TAG ATTRIBUTES Passive RFID Active RFID Tag Power Source Energy transferred using Internal to tag RF from reader Tag Battery No Yes Availability of power Only in field of reader Continuous Required signal strength Very High Very Low to Tag Range Up to 3-5m, usually less Up to 100m Multi-tag reading Few hundred within 3m 1000’s of tags recognized of reader – up to 100mph Data Storage 128 bytes of read/write Up to 128Kb or read/write with sophisticated search and access RFID READER Readers are radio frequency devices that: Transmit and receive RF signals. Contain a control unit to execute commands. Receives commands from a host computer. The reader has three main functions: Energizing Demodulating Decoding WORKING OF RFID WHAT IS RFID USED FOR? Supply Chain Management. Real Time Location. People Tracking. Baggage Tracking. Drugs Authentication. Vehicle ID. Electronics Locks and Seals. Livestock. CAMPUS MANAGEMENT SUITE USING RFID.… CAMPUS MANAGEMENT SUITE This uses contact less automatic identification technology for identification of students. Almost 15% of a lecture time in a college is taken up by an inevitable part i.e., ”ATTENDANCE”. RFID card will be used to automate attendance, managing and hence reduce the time required to take attendance and a lot of clerical work. This aims at recording the entry and exit of all cardholders. This system will enable any authentic user to find the approximate location of any card holder at a particular moment. LIST OF FUNCTIONALITIES AND MODULES Attendance Management System Library Transaction Management Human Tracking Management ATTENDANCE MANAGEMENT SYSTEM LIBRARY TRANSACTION MANAGEMENT HUMAN TRACKING SYSTEM ADVANTAGES RFID is fast and reliable. RFID does not require line of sight or contact between reader and the tagged item unlike barcodes . RFID can read hundreds of tags virtually simultaneously. RFID can read “out of sight” items. DISADVANTAGES Expensive compared with Bar code. Bulky Antennas. Prone to physical/electrical damage due to environmental conditions. Privacy. Interference with other wireless. WHAT TO EXPECT…? Larger memory capacities. Wider reading ranges. Faster processing. It is highly unlikely that this technology will ultimately replace BARCODES. RFID will continue to grow its established niches where other optical technologies like barcodes are not effective. CONCLUSION Our campus management suite will automate various manual processes like attendance recording and management, library management. This in turn will lead to saving of time, reduce number of human errors and will hence reduce the physical efforts of the concerned people. In short it is a data acquisition, maintenance and management. THANK YOU… QUERIES……?
