RFID

Definition

RFID, or Radio Frequency Identification, is a technology that uses radio waves to automatically identify and track tags attached to objects. This technology allows for the wireless transmission of data between a reader and an RFID tag, making it useful in various applications, including monitoring and detecting events like forest fires and natural disasters. By enabling real-time data collection and tracking, RFID plays a critical role in enhancing the efficiency and effectiveness of disaster management systems.
