Radio-frequency identification (RFID) is a technology that uses communicating via radio waves to exchange data between an electronic label and a reader attached to an object, with the aim of identification and tracking. Some labels may be read away and beyond the reader's line of sight. The application of mass reading enables a nearly parallel reading of tags.
Radio-frequency identification involves interrogators (also known as readers), and tags (also referred to as to labels).
One is an integrated circuit for processing and storing information, modulating and demodulating a radio-frequency (RF) signal, and other functions that are specialized.
Two-way radio transmitter-receivers called interrogators read its response and or readers send a signal to the tag.
RFID labels may be either passive, active or battery-assisted passive. An active tag has an onboard battery and periodically conducts its ID sign. A battery-assisted passive (BAP) has a small battery on board and is activated when in the existence of an RFID reader. A passive tag is smaller and not more expensive because it doesn't have any battery the label uses the radio energy transmitted by the reader. However, to control a passive tag, it has to be illuminated using a power level around a thousand times stronger than for signal transmission. That makes a difference in exposure as well as in hindrance to radiation.
