Passive ultra-high frequency (UHF) RFID technology is widely used in various industries for tracking and identifying items. Some common applications of passive UHF RFID technology include: Inventory management: Passive UHF RFID tags are used to track inventory in retail stores, warehouses, and distribution centers. Supply chain management: Passive UHF RFID technology is used to track goods as they move through the supply chain, from manufacturers to distributors to retailers. Asset tracking: Passive UHF RFID tags can be attached to equipment, vehicles, and other assets to monitor their location and status. Healthcare: Passive UHF RFID tags can be used to track medical equipment, supplies, and patients in hospitals and other healthcare settings. Access control: Passive UHF RFID tags can be used for access control, such as tracking employee badges or allowing access to secure areas. There are two main frequency ranges used for passive UHF RFID technology globally, based on the standards set by the Federal Communications Commission (FCC) in the United States and the European Telecommunications Standards Institute (ETSI) in Europe. These are: ESTI -: 865–868MHz: This frequency range is used in Europe, Africa, and Asia. FCC -: 902-928MHz: This frequency range is used in the USA & Canada and south America and Asia. In addition to these global standards, there are also regional variations in frequency ranges used for passive UHF RFID technology, such as the 950-956MHz range used in Japan.
