1 J.J. Faxon Andy Vu Dustin Beck Jessica Bentz Mandi Ellis RFID TECHNOLOGYThe Wave of the FutureJ.J. FaxonAndy VuDustin BeckJessica BentzMandi Ellis
2 Outline History of RFID Types & Systems Current Uses Future ApplicationsControversies
3 What is RFID?A technology that employs a microchip with an antenna that broadcasts its unique identifier and location to receivers.Employs a microchip called a smart tag, broadcasts unique 96-bit identifier to receiver.Receiver relays the data to a computer.
4 RFID vs. Bar CodesDoes not require human to manually pass item over scanner.More accurate inventory count.Can be incorporated into product, person, animal.Can track each individual item.
5 History of RFID 1939 1945 IFF Transponder Used by allies in WWII Leon ThereminEspionage tool for Soviet Union
6 History cont. 1973 1980 Claims U.S. patent was first true ancestor RetailUse of RFID in tracking and access applications appearedPrice, color, date of purchase
7 RFID Tags Contains two main parts: Silicon chipsAntennasComponents enable tags to receive and respond to radio frequencies queries from RFID transceivers.Three types:PassiveSemi-PassiveActive
8 RFID Tags cont. Passive Have no internal power supply Electrical current inducted in antenna by the incoming signal proves power for integrated circuit in tag to power up and transmit responseVery Small, Limited Range, Unlimited LifeSemi PassiveSimilar to passive tags, with the addition of a small batteryBattery powers the integrated circuitBigger, Longer Range, Limited LifeActiveHave their own internal power sourceMany operate at fixed intervalsAlso called beacons (broadcast own signal)Large ( coin), Much larger memories, Longer range
9 RFID System Objects equipped with RFID tag Tag contains transponder with digital memory chip.Interrogator: an antenna packaged with transceiver and decoder.emits signal activating tag.Reader detects activation signal, decodes the data on the tag’s silicon chip.Data passed to host computer.
10 Growing Technology “Line of Sight” Technology RFID superior over BarcodeElements and accidents can disturb or damage barcodesBest Buy, Wal-Mart, And Target began implementationEfficient in ability to track & respond accordingly
11 Current UsesWal-Mart now requires its suppliers to use RFID tags on shipping crates and pallets to improve inventory management in the supply chain.Fed Ex bought RFID-enabled aircraft from Airbus to reduce maintenance time and costs.Cattle and farm animals are being tagged to improve tracking and monitoring of health.
12 Current Uses cont.U.S. Department of Defense – to better track goods along supply chain (logistics and inventory).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.
13 The Future of RFID Household Technology Medical Drug Counterfeiting Smart keysIntelligent washing machinesMonitoring refrigeratorsIntelligent ovens/microwavesMedicalDrug CounterfeitingTracking & TracingMedical “Passports”Foster Care SystemFood Chain PrecautionsShoppingCashier-less check out and payment
14 Controversy Privacy Consumer Rights Tracking of consumers (Profiling) Consumers should be informed if their products have an RFID tag.Tracking of consumers (Profiling)RFID chips withstand dirt and scratches and can be scanned from distances upward of 25 feet.Personal Information Leakage.Drawing the Line – Need for Legislation?Who Should Regulate?
15 Controversy cont. “Killing” of RFID Tags Medical Tracking vs. the washing machineOptions of killing after purchaseMedicalImplants/Personal InformationVerichip is a tiny implantable chip that holds medical recordsBracelets to track infants in medical wards and elderly in nursing homes.Used in animals for tracking.
16 Controversy cont. Medical Religious Health Risks Hard to remove once implanted.Long term effects unknown.ReligiousMark of the Beast, etc.The implanted RFID chip is certain to inflame Christian fundamentalists, some of whom believe that such chips are the Satanic “mark of the Beast” predicted in Revelations 13:16 “And he causeth all, both small and great, rich and poor, free and bond to receive a mark in their right hand, or in their foreheads.”
17 Main Points Slowly becoming an industry standard Speeds up the supply chain processEasier to manage inventoryContinually evolvingControversial technology
18 Questions for you…. Define RFID technology? When was RFID introduced? What are two main reasons RFID is controversial?Name the three types of RFID tags?How are they currently using RFID tags?How is RFID Technology expected to effect households?
