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

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

   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.

   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.
