10. Muhammad Wasim Raad10 Why use RFID ? To determine authentication of a package To provide automated traceability of an item

11. Muhammad Wasim Raad11 Motivation of using RFID Generate Revenue Reduce operating costs

12. Muhammad Wasim Raad12 The RFID Reader Anti- collision protocol

13. Muhammad Wasim Raad13 What is RFID? -- The Tags Tags can be read-only or read-write Tag memory can be factory or field programmed, partitionable, and optionally permanently locked Bytes left unlocked can be rewritten over more than 100,000 times

14. Muhammad Wasim Raad14 Tags can be attached to almost anything: –pallets or cases of product –vehicles –company assets or personnel –items such as apparel, luggage, laundry –people, livestock, or pets –high value electronics such as computers, TVs, camcorders What is RFID? -- The Tags

15. Muhammad Wasim Raad15 Are All Tags The Same? Basic Types: Active Tag transmits radio signal Battery powered memory, radio & circuitry High Read Range (300 feet) Passive Tag reflects radio signal from reader Reader powered Shorter Read Range (4 inches - 15 feet)

16. Muhammad Wasim Raad16 Variations: –Memory Size (16 bits - 512KBytes +) Read-Only, Read/Write or WORM Type: EEProm, Antifuse, FeRam –Arbitration (Anti-collision) Ability to read/write one or many tags at a time –Frequency 125KHz - 5.8 GHz –Physical Dimensions Thumbnail to Brick sizes –Price ($0.50 to $250) Are All Tags The Same?

17. Muhammad Wasim Raad17 Types of Tags - Memory Segmentation  Read Only (Factory Programmed)  WORM - Write Once, Read Many times  Reprogrammable (Field Programmable)  Read/Write (In-Use Programmable)

18. Muhammad Wasim Raad18 What are chipless tags? No IC Use RF fibers or materials reflect reader’s signal producing unique serial no Cost: 10-25 cents each Tolerates wide range temperature Less sensitive RF

19. Muhammad Wasim Raad19 Chipless tags 2.5% of RFID market Expected to become 30% in 2010 Chipless RFID smart labels have a range of 10 meters

20. Muhammad Wasim Raad20 What is RFID? -- The Readers Readers (interrogators) can be at a fixed point such as –Entrance/exit –Point of sale –Warehouse Readers can also be mobile -- tethered, hand-held, or wireless

21. Muhammad Wasim Raad21 Advantages Uses normal CMOS processing — basic and ubiquitous Relative freedom from regulatory limitations Well suited for applications requiring reading small amounts of data at slow speeds and minimal distances Penetrates materials well (water, tissue, wood, aluminum) <150 kHz (125 kHz & 134 kHz )

22. Muhammad Wasim Raad22 Disadvantages: Does not penetrate or transmit around metals (iron, steel) Handles only small amounts of data Slow read speeds Large Antennas -- compared to higher frequencies Minimal Range <150 kHz (125 kHz & 134 kHz )

23. Muhammad Wasim Raad23 Disadvantages: Tag construction: 4 is thicker (than 13.56 MHz) 4 is more expensive (than 13.56 MHz) 4 more complex (requires more turns of the induction coil) <150 kHz (125 kHz & 134 kHz )

24. Muhammad Wasim Raad24 13.56 MHz Advantages Uses normal CMOS processing--basic and ubiquitous Well suited for applications requiring reading small amounts of data and minimal distances Penetrates water/tissue well Simpler antenna design (fewer turns of the coil); lower costs to build Higher data rate (than 125 kHz--but slower than higher MHz systems) Thinner tag construction (than 125 kHz)

25. Muhammad Wasim Raad25 Disadvantages Government regulated frequency (U.S. versus Europe) Does not penetrate or transmit around metals (unless very thick) Large Antennas (compared to higher frequencies) Larger tag size than higher frequencies Tag construction: requires more than one surface to complete a circuit Minimal Range 13.56 MHz

26. Muhammad Wasim Raad26 Bar Codes vs. RFID

27. Muhammad Wasim Raad27 RFID Applications Petrol Service Stations –In Singapore, the Mobil petrol service stations has already introduced RFID technology to implement their Speed Pass system to enable drivers to fill up the petrol and drive away. All information will be gathered automatically through RFID smart tags and customers’ bills can be settled through the net.

28. Muhammad Wasim Raad28 RFID Application in Petrol Service Station

29. Muhammad Wasim Raad29 RFID Application in a Factory Canteen it is very interesting to notice that in the factory canteen’s environment, RFID tags are attached at the bottom of the plates to identify the cooked food and its price. The staff of the factory need only to pick up the food on the tray and place the tray on top of a RFID reader. The RFID reader will identify the products and its price. The staff need only to place the cash card to pay for the food.
