![]() Low-power, embedded non-volatile memory plays an important role in every RFID system. There are also semi-passive RFID tags, meaning a battery runs the circuitry while communication is powered by the RFID reader. A passive RFID tag receives its power from the reading antenna, whose electromagnetic wave induces a current in the RFID tag's antenna. ![]() An active RFID tag has its own power source, often a battery. The part of an RFID tag that encodes identifying information is called the RFID inlay. RFID tags are made up of an integrated circuit (IC), an antenna and a substrate. Tags that have a stronger power source also have a longer read range. The read range for RFID tags varies based on factors including the type of tag, type of reader, RFID frequency and interference in the surrounding environment or from other RFID tags and readers. The transponder is in the RFID tag itself. ![]() Once activated, the tag sends a wave back to the antenna, where it is translated into data. It uses radio waves to transmit signals that activate the tag. The RFID reader is a network-connected device that can be portable or permanently attached. There are two types of RFID readers - fixed readers and mobile readers. When the scanning antenna and transceiver are combined, they are referred to as an RFID reader or interrogator. How does RFID work?Įvery RFID system consists of three components: a scanning antenna, a transceiver and a transponder.
