1. LF (Low Frequency) RFID tags: the operating frequency range of 125kHz to 134kHz, characterized by a shorter transmission distance, smaller data storage capacity, suitable for near-field applications.
2. HF (high-frequency) RFID tags: operating frequency range of 13.56MHz, characterized by medium transmission distance, data storage capacity is larger, suitable for far-field applications.
3. UHF (Ultra High Frequency) RFID tags: operating frequency range of 860MHz to 960MHz, characterized by a longer transmission distance, larger data storage capacity, suitable for logistics, supply chain management and other applications.
4. microwave (microwave) RFID tags: operating frequency range above 2GHz. Characterized by fast transmission speed, suitable for high-speed logistics and license plate recognition and other applications.
RFID tags can be applied in the laboratory to realize the tracking, management and security control of items and other functions. For example, the use of low-frequency or high-frequency RFID tags in the laboratory to mark the experimental equipment, reagents, samples and other items, through the RFID reader can be a real-time record of the location and status of the items, to facilitate the laboratory personnel to lend, return and inventory management. In addition, RFID technology can also be applied to laboratory security control, such as the use of RFID tags as access control cards, only carry a valid RFID tag personnel can enter a specific area to ensure the safety of the laboratory.
Expand to add: RFID tags have a wide range of applications. In addition to applications in laboratories, RFID technology can also be used in logistics, retail, healthcare, transportation and other fields. In logistics and supply chain management, RFID tags can be used for tracking and traceability of goods; in the retail industry, RFID tags can be used for inventory management and anti-theft of goods; in the medical field, RFID tags can be used for tracking and proofreading of medicines; in the transportation field, RFID tags can be used for vehicle identification and toll collection systems.
In short, RFID tags are a very useful IoT technology that can improve efficiency, reduce workload, and can play an important role in different fields.
