PRESENTATION OUTLINEIntroductionWorkingApplicationsAdvantagesDisadvantagesFuture usesConclusion
What is RFID?RFID stands for Radio-frequency
identification(RFID) an Auto data collection system surveillance, using RF waves for Identifying, Tracking and doing Management of material flow.
It is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product for the purpose of identification using radio waves.
• Is fast and does not require physical sight or contact between reader/scanner and the tagged item.
• Basic concept behind RFID is same as “Mirror-Sunlight-Reflection theory.
• Invented and used from early 1940’s but Commercial operation begun from 1960’s.

Data Processing Subsystem
Transponder• Consists of silicon based microchip that stores data and
antenna. Tags can be classified in three different ways : Active, Passive, Semi active (semi passive)• Active transponders have on-tag batteries and also known
as beacons (broadcast its own signal).• Passive transponders obtain all power from the RF
interrogation signal of reader.• Active and passive only communicate when interrogated by
transceiver. Tags can also be classified on the basis of:• Read-only (RO)• Write once, read many (WORM)• Read-write (RW)
SMART LABELS (tags)Typical Frequency: 13.56 MHz-HF system uses passive
tags - a worldwide standardized frequencyLibraries use high frequency passive tagsIn our library we paste these tags on the preface page
of the book Presently four main frequency bands used in RFID
systems
Low Frequency band: 125/134 KHz
High Frequency band: 13.56 MHz
Ultra High Frequency band: 800-900 MHz
Microwave band: 2.4-5.8 GHz
READER• A device that is used to interrogate an Tag.
Basic components are:
A scanning Antenna
A transceiver with a decoder to interpret data
helps in personalize & read data.

How does RFID work?
working
A radio device called a tag is attached to the object that needs to be identified.
When this tagged object is presented in front of a suitable RFID reader, the tag transmits this data to the reader (via the reader antenna).
The reader then reads the data and has the capability to forward it over suitable communication channels.
This application can then use this unique data to identify the object presented to the reader.
It can then perform a variety of actions
RFID tags - Active vs. Passive
Active RFID Passive RFIDTag Power Source Internal to tag Energy transferred using
RF from reader
Tag Battery Yes No
Availability of power Continuous Only in field of reader
Required signal strength to read tag
Very Low Very High
Range Up to 100 meters Up to 3-5m, usually less
Multi-tag reading 1000’s of tags recognized – speeds up to 100 miles/hour.
Few hundred within 3m of reader
Data Storage Up to 1Mb of read/write with sophisticated search and access
128 bytes of read/write

Access Control Hand Implants ID badges
Payment Systems The American Express Blue Card, a feature they call Express
Pay Exxon Mobile Speed Pass Airline baggage tracking Cell phones are including RFID tags built in Electronic payment – credit card companies moving to RFID-
enabled cards to increase efficiency and reduce time at point-of-sale for customer, merchant, and card issuer.
Commercially for truck and trailer tracking in shipping yards Long range access control for vehicles

Smart groceries
• Add an RFID tag to all items in the grocery.
• As the cart leaves the store, it passes through an RFID transceiver.
• The cart is rung up in seconds.
Smart groceries enhanced
• Track products through their entire lifetime.

RFID Implants
Before After implant surgery
RFID animal tracking systemCattle and farm animals are being tagged to
improve tracking and monitoring of health.
AdvantagesContactless. An RFID tag can be read without any
physical contact between the tag and the reader.Writable data. The data of a read-write (RW) RFID tag
can be rewritten a large number of times.Absence of line of sight. A line of sight is generally
not required for an RFID reader to read an RFID tag.Variety of read ranges. Wide data-capacity range. Support for multiple tag reads. Perform smart tasks. Better collection managementImproved productivity and services.
Inventory ManagementRead/Write
- Ability to add information directly to tags enables each unique asset to carry its own unique history
Non-contact Reads - Ability to read tags at a distance, under a
variety of environmental conditions, without physical manipulation of the asset
Fast Read - Ability to simultaneously read large numbers
(1000-1750 tags/sec) of itemsAutomation
- Requires less human interventionAuthenticity - Each RFID chip is unique and can not be
replicated
Inventory ReaderA compact and light weight hand held device
Comfortable to use
High storage capacity
Multi functional (such as shelving,
sorting, searching, weeding and
reading)
Enhanced security
DisadvantagesPoor performance with RF-opaque and RF-
absorbent objects. Impacted by environmental factors.
Impacted by hardware interference.
Cost factors: Implementation and on going system cost.
