UHF RFID tags enable contactless identification at greater distances than NFC and, depending on the application, allow multiple tagged items to be identified quickly. Rigid UHF tags are used for assets, equipment, containers, returnable packaging, materials and other objects in warehousing, logistics and manufacturing.
Compared with NFC tags, UHF RFID is particularly useful when the reader should not need to be brought directly next to each individual tag. A properly designed system can identify items from a greater distance and improve processes such as inventory checks, goods receiving, dispatch and material tracking.
Rigid UHF RFID tags have a more durable construction than standard RFID labels and, depending on the design, can be suitable for long-term identification of equipment, tools, containers, pallets and other assets. Tags differ in dimensions, mounting method, chip and antenna characteristics.
Important selection criteria include required read range, material of the tagged object, tag dimensions, installation position, mounting method and operating environment. Applications on metal or near liquids require particular attention because these materials can significantly affect RFID performance.
Actual read performance does not depend on the tag alone. It is also influenced by the RFID reader, RFID antenna, system configuration, tag orientation and surrounding environment. For demanding applications, the complete solution should therefore be tested under real operating conditions.
UHF RFID is suitable for longer-range reading and, depending on the application, fast identification of multiple tags. NFC is primarily designed for targeted interaction with one tag at very short range.
Read range is not determined by the tag alone. It depends on tag design, reader and antenna performance, orientation, material of the tagged object and surrounding environment. The complete RFID system therefore needs to be considered.
Yes, but a tag specifically designed for use on metal should be selected. Standard RFID tags may not operate correctly on metal because the surface significantly affects the tag antenna.
Yes. One of the key advantages of UHF RFID is fast identification of multiple tags within the reader field. Actual performance depends on the reader, antennas, number and position of tags and the operating environment.
