Identification is pervasive nowadays in daily life due to many complicated activities such as
bank and library card reading, asset tracking, TOLL collecting, restricted access to sensitive data
and procedures and target identification. This kind of task can be realized by passwords, bio-
metric data such as fingerprints, barcode, optical character recognition, smart cards and radar.

It is a contactless, usually short distance, wireless data transmission and reception technique
for identification of objects. An RFID system consists of two components: the tag (also called
transponder) and the reader (also called interrogator).

Radio frequency identification (RFID) is a type of automatic identification systems
which has gained popularity in recent years for being fast and reliable in keeping
track of the individual objects. In RFID systems, contactless object identification
is achieved using radio signals without the need for physical contact as the case
with other existing identification technologies such as barcodes. Therefore, a huge
number of items can be identified in a short amount of time with high reliability
and low cost which makes the RFID technology very attractive for a wide range of
applications such as supply chain management, e-health, monitoring humans, pets,
animals, and many other objects, TOLL control, and electrical tagging. Furthermore,
RFID technology eliminates the human error and reduces the total cost of the
products.
