<h2>Introduction to UHF Tags</h2>

Ultra-High Frequency (UHF) tags represent a significant advancement in the field of Radio Frequency Identification (RFID) technology. These tags operate within the frequency range of 860 MHz to 960 MHz, enabling efficient and long-range communication with RFID readers. Unlike their Low-Frequency (LF) and High-Frequency (HF) counterparts, which are often used in access control or payment systems (like NFC), UHF tags are designed for applications requiring bulk reading and extended read ranges. The core functionality of UHF tags lies in their ability to store and transmit data wirelessly, making them indispensable in modern supply chain management, inventory tracking, and asset monitoring. As industries increasingly adopt automation and IoT solutions, the demand for UHF tags continues to grow, driven by their cost-effectiveness, scalability, and performance.

<h2>How UHF Tags Work</h2>


UHF tags consist of an integrated circuit (IC) and an antenna, encapsulated in a protective material such as plastic or paper. The IC stores unique identification data and other relevant information, while the antenna facilitates communication with RFID readers via electromagnetic waves. When a UHF reader emits a radio signal within the appropriate frequency band, the tag's antenna captures this energy, powering the IC to transmit its stored data back to the reader. This process, known as backscattering, allows for passive UHF tags to operate without an internal battery, relying solely on the reader's energy. Active UHF tags, which include a battery for extended range and functionality, are also available but less common due to higher costs. The read range for passive UHF tags can vary from a few meters to over 10 meters under optimal conditions, depending on factors like tag design, reader power, and environmental interference.
