Understanding RFID Tags: How RFID Tags Work and Their Uses
Introduction to RFID Tags Radio Frequency Identification (RFID) tags are small devices that use radio waves to transmit data to an RFID reader. These tags are integral to RFID systems, which track and identify objects wirelessly. RFID tags are commonly used in various industries, including retail, healthcare, logistics, and more, to streamline operations, enhance security, and improve inventory management. How RFID Tags Work RFID systems comprise three main components: the RFID tag, the RFID reader, and the antenna. RFID Tag : This small device contains a microchip and an antenna. The microchip stores a unique identifier and other data, while the antenna transmits this information to the RFID reader. RFID tags are differentiated by their radio frequencies: low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). LF systems operate within the 30-300 KHz range and can read up to 10 cm, commonly used for access control and livestock monitoring. HF systems op
