Radio-frequency identification (RFID) systems operate via radio waves in many different frequency ranges, with some of the most common being low-frequency (LF), high-frequency (HF), ultrahigh-frequency (UHF), and microwave. The frequency helps determine such things as range and method of communication (for example, between transmitter and receiver). In its simplest form, as shown in Fig. 1, an RFID system consists of a tag (attached to the product to be identified), an interrogator (reader), and one or more antennas attached to the reader. The reader must be connected to a computer either directly or through a network to provide control for the reader and to capture the data.
