Radio frequency identification (RFID)
Radio frequency identification (RFID) is a technique of using radio frequency (RF) electromagnetic waves to identify objects that carry identifying transponders. Radio frequency identification (RFID) allows identification data to be transferred remotely which provides a significant advantage in identifying persons, articles, parcels, and others. Radio frequency identification (RFID) systems generally consist of a reader, also known as an interrogator, and a remote tag, also known as a transponder. The RFID reader includes a transmitter that may provide energy or information to the tags, and a receiver to receive identity and other information from the tags. The reader transmits high voltage excitation signals into the surrounding space, which are received by a transponder proximal to the reader and which provide operational electrical power for the internal electronics of the recipient transponder. Once the transponder is powered up, it communicates information to the reader in a contactless manner. The interrogator includes a receiver that receives the response signal and processes the information it contains. This information is then recorded by a data management system for access by the end user. Radio frequency identification tags have the capability to store information related to a product on an integrated circuit. The information is retrieved through an RFID interrogation device. RFID tags with a power storage device are known as active tags. Advances in semiconductor technology have miniaturized the electronics so much that an RFID tag can be powered by the RF signal it receives enough to be operated. Such RFID tags do not include a power storage device, and are called passive tags. Passive RFID tags usually include an analog circuit that detects and decodes the interrogating RF signal and that provides power from the RF field to a digital circuit in the tag. The digital circuit generally executes all of the data functions of the RFID tag, such as retrieving stored data from memory and causing the analog circuit to modulate to the RF signal to transmit the retrieved data. Radio frequency identification (RFID) systems are used in a wide variety of applications, and provide convenient mechanisms for the tracking, identification, and authentication of persons or objects. Radio frequency identification technology has become widely used in virtually every industry, including transportation, manufacturing, waste management, postal tracking, airline baggage reconciliation, and highway toll management.
