4. 1. About RFID

5. KEY COMPONENT TO BE USED FOR CLASS ATTENDANCE
A) An RFID Tag
b) An RFID Antenna
C) An RFID Reader
D)GSM MODULE
e) An RFID Station/PC

6. AN RFID TAG

7. An RFID Tag are made of :-
1)Chip :- Hold information about physical object
2)Antenna :-Transmit signal at radio frequency
3)Package :-encase chips and antenna so that
tag can be attached to physical object
Tag are
Active Tag Passive Tag
Power –Battery Power-No(get from reader
through mutual inductance)
Signal –stronger Signal –Weaker
Range-100 feet Range-upto 30 feet
NOTE :- These cards are known as proximity card

8. AN RFID READER
An RFID Reader is a device used to gather data
information from an rfid tag,which is used to track
individual objects.Radio waves are used to transfer
data to RFID reader from an rfid tag

9. Transfer of energy from one circuit[READER] to
another[CARD] by mean of electromagnetic
waves at Radio frequency through mutual inductance

10. INTRODUCTION
GSM is a 2nd generation[2-G] cellular standard
developed to cater voice services and data delivery
using time division
multiplication access[TDMA]
GSM SERVICES
Tele services :-Includes mobile phones and emergency
calls etc.
data services :-Includes SMS(short messge
service),Fax,voice mail,electronic-mail.
Supplementary service:-I/C&O/G calls,call forwarding,call
holding,call waiting,conference etc.

12. 1.)Communication :-mobile,wireless
communication,support for voice and data services
2.)Total mobility :-International access,chip-card enables use
of access points of different providers
3.)World wide connectivity :-one number,the network
handles every location
4.)High capacity :-better frequency efficient,smaller cells
more,customer per cell
5.)High transmission capacity :-High audio quality and
reliability for wireless,uninterrupted phone calls at higher
sppeds(e.g.,from cars and trains)
ADVANTAGE OF GSM

14. RFID BASED ATTENDANCE SYSTEM

15. FLOW CHART

16. COMPLETE BLOCK DIAGRAM OF CAS

17. 1.)Proxy attendance can be caught.
2.)Hardcopy paper work of attendandacesheet is
reduced
3.)Data can be stored long time compare to attendance
sheets.
ADVANTAGE
RFID V/S BAR CODE COMPARISON
RFID and BAR Codes are similar in that they are both data
collection technologies,meaning they automate the
process of collecting data.

18. Line of sight Not required (In most cases) Required
Read Range Passive UHF RFID :
-upto 40 feet(fixed readers)
-upto 20 feet(handheld readers)
Active RFID :
-upto 100’s feet or more
Several inches upto
several feets.
Read Rate 10’s,100’s,or 1000’s simultaneously Only one at a time
Identification Can uniquely identify each item
/asset tagged
Most barcodes only
identify the type of
item(UPC code)but
not uniquely
Read/Write Many RFID tags are Read/Write Read only
Technology RF(Radio frequency) Optical(LASER)
Interference Like TSA(Transportation security
administration),same RFID
frequencies don’t like metal and
liquids.They can interference with
same RF frequencies
Obstructed barcodes
cannot be read(dirt
covering barcode,torn
barcode,etc).
Automation Most “fixed” readers don’t require
human involvement to collect
data(automated)
Most barcode
scanners require a
human to
operate(labor
intensive)

19. OTHER APPLICATION ARE
1.)people tracking
2.)Document tracking
3.)Health care
4.)Manufacturing
5.)Department of road transportation and
highways
6.)Center for railway information system
7.)Apparel tracking
8.)Laptop tracking

20. PROS AND CONS
PROS CONS
-RFID tags are very simple to
install/inject inside the body of
animal,thus helping to keep tract on
them.
-Expensiveness of technology than Bar
code
-The RFID tags can store data upto 2kb.
-The RFID technology can not be easily
replicated and therefore,it increases
the security of the product.
Collision :
-signals can ‘collide’when multiple
signals are read at once
-Those signals are either lost or read
with errors
-mobility -failure
-Unlimited scope -still evolving
-reduced human intervention

21. CONCLUSION
+RFID Is helpful in tracking assets–human
and machine
+Used in inventory control
+Scope limited by imagination of its
implementation
FUTURE PROSPECTS
+Can be extended to embedded system
Ex:-so the RFID chip can be embedded within the
laptop for tracking
+Application software can be made web based
