The tag is typically more expensive, often costing $20 or more each The long-term maintenance costs for an active RFID tag can be greater than those of a passive tag if the batteries are replaced. Battery outages in an active tag can result in expensive misreads.RFID: Passive, How it WorksDiagram SourceRFID: Passive, AdvantagesThe tag functions without a battery; these tags have a useful life of twenty years or more. The tag is typically much less expensive to manufacture The tag is much smaller (some tags are the size of a grain of rice). These tags have almost unlimited applications in consumer goods and other areas.RFID: Passive, DisadvantagesThe tag can be read only at very short distances, typically a few feet at most. It may not be possible to include sensors that can use electricity for power. The tag remains readable for a very long time, even after the product to which the tag is attached has been sold and is no longer being tracked.Common Applicationshttp://youtube.com/watch?v=llnUJkH0MlcCommon ApplicationsPassportsTransport (toll) paymentProduct trackingAnimal IDCommon ApplicationsAutomotiveInventory systemsHuman implantsLibraryCurrent Business ExampleBenettonMicrochip transmitters have been attached to pieces of clothing in Benetton stores -- a technological leap the Italian retailer said will help it track apparel from factory to sales floor to cash register http://www.sfgate.com/cgi-bin/article.cgi?file=/chronicle/archive/2003/03/12/BU161909.DTL&type=businessWhat do you Think?What are potential applications?Potential ApplicationsReplacing barcodesPatient IDLaundry (smart)Toll boothCredit cardsFelony scannerOthers?Ethical IssuesPrivacyHuman implantation
