• RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person
• RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFIDreader (also called an interrogator). The reader then converts the radio waves to a more usable form of data.
• A radio-frequency identification system uses tags, or labels attached to the objects to be identified. Two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.RFID tags can be either passive, active or battery-assisted passive.
