This document provides an overview of radio-frequency identification (RFID) technology. It discusses the history and components of RFID, including tags, readers, software, and communication networks. It then outlines several applications of RFID such as supply chain management, retail, and security/access control. Both advantages, like automatic identification without line of sight, and disadvantages, including cost and need for regulations, are mentioned. The document concludes by summarizing observations on using RFID in healthcare, gaming, and human activity detection.

 Components Of RFID
 Applications of RFID
 Advantages of RFID

 Conclusion

3. Radio-frequency identification
(RFID) is the wireless non-contact
use of radio-frequency
electromagnetic fields to transfer
data, for the purposes of
automatically identifying and
tracking tags attached to objects.
J.F.McCarthy et al. (2003)

4.  Invented in 1948 by Harry Stockman.
H.Stockman, 1948
 The first application of RFID was during
World War II when it was used in conjunction
with rader technology for Friend and Enemy
identification
K.Dittmer,2004
 Came into commercial use only in 1990s.
J.Landt ,2005

5. RFID system consists of four
components:
 The tag (transponder )
 The reader
 The RFID software and
 The communication network

6. A tag is a transponder which receives
a radio signal and in response to it
sends out a radio signal.
Tag can be programmed at
manufacturing or on installation

7. There are three types of tag
(transponder ):
1. Passive tag.
2. Active tag.
3. Semi-passive tag.

8.  Passive tags do not carry on-board power
i.e; these are operated without battery.
 Derive power from the field generated
by the reader to enable reading and
writing on tag
 Less expensive .
 Unlimited life.
 Subject to noise.
 Require more powerful reader.

9.  Powered by an external battery
 Finite lifetime (because of battery)
 Greater range
 Better noise immunity
 Higher data transmission rates

10. RFID tags are divided into three frequency
regions:
 Low frequency (LF, 30-50 kHz)
 High frequency ( HF, 10-15 MHz)
 Ultra high frequency ( UHF, 850-950 MHz)
Low frequency tags are cheaper than all high
frequency tags. These tags are less influenced by
the presence of fluids or metals and disadvantage
of their low transmission speed.
[M.Ward et al.,2006]

11. High frequency tags have higher
transmission speed but they are expensive
than LF tags.
Ultra high frequency tags have the
highest rank of all tags.Their transmission
speed is extremely high .But these are
expensive than other high frequency and
low frequency tags
[M.Ward et al., 2006]

12. RFID reader is a device that is used to
interrogate an RFID tag. The reader has an
antenna that emits radio waves ; the tag
responds by sending back its data.
[ Wisner et al.,]

13. Two main types of readers are:
1. Portable reader.
2. Fixed reader.
Portable readers can read or
write data almost anywhere and are
mobile.
Fixed readers are installed at
one place eg., in the doors for the for the
identification of people,goods or vehicles.

14.  RFID Software is the most critical piece
of an RFID application. It determines
what kind of hardware is required to
complete your system. Whether you are
tracking assets,preventing theft or
conducting inventory, we have the RFID
Software to meet your needs.

15.  Communication network is necessary to
allow companies to interact with each
other. It also helps to solve problems
with security and authentication.

17.  Identification of the instance
 Location identification
 Monitoring of resources
 Management of the supply chain
 Retail trade
 Production
 Security and access control

18.  The tag does not need to be in line of sight with
the receiver to be read.
[Shepard ,2004 , p.58.]
 RFID tags can store a lot of information.
 Labour reduction . [Keith et al.,2002]
 Asset tracking and Returnable items.
[Luke et al.,2005]

19.  Active RFID can be expensive because of
batteries.
 There still needs regulations about RFID
guidelines.
 It takes a lengthy time to program
RFID devices.

20.  After examining the three fields Health
care, Games and Human Activity
Detection with
regard to the usage of RFID technology
we will now try to present the overall
observations and draw some
conclusions.
 Above all there is the need for small tags
but especially for smaller readers.
