Background
CE 1.1) RFID (Radio frequencyIdentification) technology is one of the most evolved technique in our
contemporary time with huge potential ranging from applications as simple as
implementation a gate security system to as complex and exigent as automatic
money transfer system. The project for designing and implementing a RFID system
for libraries employs the broader use of radio frequency technique along with
PLCs in algorithm for security control, access control and tracking system of
the library.
CE 1.2) RFID technique is an upgrade
from bar-code technique which has been previously employed for realizing the
same task. The bar-code consist of images of lines affixed with varying spacing
against which there is information stored for the particular product to which
the specific barcode has been assigned. Unlike RFID, bar-code technique uses
light transmission for communication between the ‘reader’ and the bar-code. The
reader in this case gather the information from the barcode and converts it
into digital data for practical use.
