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 goods can be monitored for temperature, problem areas identified and alarms raised. Some developments and uses The US military has used RFID technology since the early 1990s with the first deployment to Bosnia in the mid 1990s. The United Kingdom armed forces adopted RFID in 2021 and negotiations are in progress with NATO partners. The US Department of Defense and WalMart require their major suppliers to implement RFID technology in their supply chains by 1 January 2021. All cartons and pallets must be equipped with RFID tags. This will provide a major impetus for the widespread adoption of the technology in the US. UK39。s port operation have agreed to deploy RFID tags to track the 17,000 containers that arrive at US ports daily. Star City Casino in Sydney has placed RFID tags in 80,000 employee uniforms in an attempt to curb the theft of the uniforms. The new Wynn Las Vegas casino has incorporated RFID into betting chips to curb the use of fake chips, misuse of credit facilities and late placement of bets. Michelin is planning to build RFID tags into its types. The tag will store a unique number for each type, associated with the vehicle39。s most counterfeited currency. However, with the growth of
