Abstract
RFID technology will be used in the smart cards . Each card will
have RFID and store about 8-16 bit of data regarding the
student . Every student will have such cards of their own. In library
all books will be attached a RFID tag and each will be assigned
unique codes accordingly. Doorway of the library will be
redesigned and will have readers of RFID tags. For , an instance
when a student carrying books and with Smart ID card together
goes through the door with reader both data of book and card are
read, simultaneously books get issued with details stored at
workstation.
In the Lecturer halls and at college main gate readers will be
incorporated maintaining records of the students entering and
leaving the college. This will save time wasted in attendance and
also helps in increasing security.
WORKING PROCESS OF RFID
Host manages Reader(s) and issues Commands
Reader and tag communicate via RF signal
Carrier signal generated by the reader
Carrier signal sent out through the antennas
Carrier signal hits tag(s)
Tag receives and modifies carrier signal -“sends
back” modulated signal (Passive Backscatter – also
referred to as “field disturbance device” )
Antennas receive the modulated signal and send
them to the Reader
Reader decodes the data
Results returned to the host application
SMART CARDS and LABELS IN LIBRARY
Queues for 2-3 Hours- Library of Nit Srinagar has enormous
amount of space for keeping the books. But when the space
provided for issuing is quite compact and catering needs of
about 2500 students becomes inadequate.
Quite cumbersome. During exams time queues for issuing
books lasts for 2-3 hours. Hence, this problem needs to be
sorted out.
Thefts- There has been certain cases of theft been reported
throughout the years and hence, it has lead to decrease in
availability of books pertaining to important topics and hence is
a critical problem library is facing now.
. Problem in Locating of books- There are number of incidences
when books are present in the college but we are unable to
locate where it is present.
