The document discusses the applications of radio frequency identification (RFID) technology, particularly in automation at tollgates and library systems. It highlights the advantages of RFID tags, such as low power requirements and small size, along with their growing use for asset tracking and other industries. However, it also notes some limitations of RFID, including high costs and security concerns.

2.  Radio frequency identification(RFID)
technology using at various application by
using radio frequency ranges.
 It is especially used at tollgates. For automation
of gate control.
 It can also used at library systems.

3.  RFID tags
 Reader
 The RFID tags and reader that communicate
with each others.
 This makes it easy and cheap to apply tags to
all identifying or tracking area.

4.  RFID tags are so small.
 Its required so little power that do not need a
battery to store information and exchange the
data with reader.
 Its read the relevant data from the reader.
 Its also known as Transponder.

5.  Its also known as Interrogator.
 Interrogation means wireless. The distance
between transmitter and receiver is so small.
 A reader consist of RF module, which act as
both transmitter and receiver of radio
frequency signal.

6.  RFID use is increasing rapidly with capability
to tags for the communication purpose between
tags and reader.
 Endless chain management to asset tracking to
authentication of frequency counterfeited.

7.  Retail application
 Homemade chocolates
 Spare parts for surgery
 Sport goods
 Document tracking

8.  Reliability
 Eliminating the human error
 Has read/write memory compared to barcodes
 Less sensitivity
 Automatic reading facility.

9.  High cost
 Collision
 Limited frequency range
 Less security.
