RFID Technology

RFID (Radio Frequency Identification) is an advanced automatic identification (Auto ID) technology that uses radio
frequency signals to identify tagged items. An RFID tag contains a circuit that can store data. This data may be
pre-encoded or can be encoded in the field. The tags come in a variety of shapes and sizes.
A typical RFID system consists of transponders (called tags), readers, and antennas. To read a tag the reader
sends out radio frequency waves (using attached antennas). This RF field powers and charges the tags, which are
tuned to receive radio waves. The tags use this power to modulate the carrier signal. The reader interprets the
modulated signal and converts the data to a format for computer storage. The computer application translates the
data into an understandable format.
