PRESENTATION OUTLINE
1. About RFID
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
AN RFID TAG
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 objectTag are
Active Tag Passive TagPower –Battery Power-No(get from reader
through mutual inductance)
Signal –stronger Signal –WeakerRange-100 feet Range-upto 30 feet
NOTE :- These cards are known as proximity card
AN RFID READERAn 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
OPERATING PRINCIPLE
Transfer of energy from one circuit[READER] to another[CARD] by mean of electromagnetic
waves at Radio frequency through mutual inductance
GSM MODULEINTRODUCTION
GSM is a 2nd generation[2-G] cellular standard developed to cater voice services and data delivery
using time division multiplication access[TDMA]
GSM SERVICESTele 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.
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

COMPLETE BLOCK DIAGRAM OF CAS
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.
RFID BAR CODELine 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 onlyTechnology 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)
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 system7.)Apparel tracking
8.)Laptop tracking
PROS AND CONSPROS 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
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
