A Introduction to RFID Technology Radio-Frequency Identification (RFID) technology has become increasingly prevalent in modern society, playing a crucial role in various applications, particularly in the realms of personal identification and payment systems. At its core, RFID utilizes electromagnetic fields to automatically identify and track tags attached to objects. These tags, which can be passive or active, contain an integrated circuit and an antenna that facilitate communication with RFID readers through radio waves. The technology operates by sending a signal from the RFID reader, which is then intercepted by the tag. This connection allows the transmission of information stored within the tag to the reader, enabling swift identification and data retrieval without requiring direct line-of-sight. RFID is commonly found in … Continue reading →
