8.1 Introduction
Radio frequency identi?¬?cation (RFID) is an automatic identi?¬?cation system which consists
of readers and tags. An RFID reader recognizes an object through reading the identi?¬?cation
number (ID) of the RFID tag attached to it [1]. To read tag IDs, the reader sends out a signal
supplying instructions to tags.
