UHFRFID

UHF RFID refers to Ultra High Frequency Radio-Frequency Identification. This technology utilizes radio waves to automatically identify and track tags attached to objects. UHF RFID operates within a frequency range typically between 300 MHz and 3 GHz, with common bands being 860-960 MHz globally. This frequency range allows for longer read ranges and faster data transmission compared to lower frequency RFID systems.

UHF RFID tags are passive or active. Passive tags are powered by the radio waves emitted by the reader, making them less expensive and requiring no internal battery. Active tags have their own power source, enabling them to transmit signals over greater distances and store more data. The core components of a UHF RFID system are the tags themselves, the readers that emit radio waves and receive data, and an antenna to facilitate communication.

Applications for UHF RFID are widespread. They are commonly used in supply chain management for inventory tracking, in retail for point-of-sale systems and anti-theft measures, and in logistics for streamlining warehouse operations. Other uses include asset tracking, toll collection, and even animal identification. The technology's ability to read multiple tags simultaneously and its extended read range make it an efficient solution for managing large numbers of items. However, its performance can be affected by metal and liquid objects, which can absorb or reflect radio waves.
