EAS These are typically 1bit systems used to sense the presence or absence of an object. The most mon use is in retail stores as an antitheft device. Tags are attached to clothing or other items and trigger an alarm if the goods leave the store before the tag is deactivated. These have been in widespread use for some years and are found in a variety of retail stores including clothing, small appliances, electrical goods and book stores. Portable data capture Used with portable devices where data required from the tagged object may vary. Some devices incorporate sensors to record, for example, temperature, movement (seismic) and radiation. Data can be stored on the portable device for later download and processing. Networked systems These systems are characterized by fixed position readers and used to track the movement of tagged objects. Usually directly connected to an enterprise system, this is a typical inventory application of the technology. Positioning systems These systems are used where objects (vehicles, animals or even people) are tagged and provides automatic location and navigational support. Applications Used mainly in transportation, logistics, manufacturing, processing and security, typical applications of RFID include Animal tagging Road toll collection Animal husbandry EAS Toxic and medical waste management Access control Postal tracking Time and attendance Airline baggage management Manufacturing processes with robotics Paper money anticounterfeiting Monitoring of offenders Anticounterfeiting in the drug industry Passports Vehicle immobilizers and alarms RFID standards The lack of standardization and the lack of harmonization of frequency allocation are hampering growth in this industry. There is a proliferation of inpatible standards with major RFID vendors offering proprietary systems. ANSI and ISO have been working to develop RFID standards and some have been adopted for such applications as animal tracking (ISO 11784 and 11785) and supply chain goods tracking (ISO 180003 and ISO 180006). Advantages The principal advantages of RFID system are the noncontact, nonlineofsight characteristics of the technology. Tags can be read through a variety of visually and environmentally challenging conditions such as snow, ice, fog, paint, grime, inside containers and vehicles and while in storage. With a response time of less than 100 ms, an RFID reader can read many (several hundred) tags virtually instantaneously. Tags coupled with sensors can provide important information on the state of the goods. For example, refrigerated
