What is RFID?
RFID Tags RFID tags consist of two primary components; a microchip that processes and stores the information/data and an antenna to receive and transmit RFID radio-wave signals. To read information from the tag/label, a two-way radio-receiver called an interrogator (or reader) sends a radio-wave signal to the tag(s) using its antenna. Tags that are within range of the interrogator’s signal will respond with the data stored in its memory. Most RFID tags are passive tags, which use the energy from the interrogator’s signal to relay its stored information. Alternatively, battery-powered RFID tags use
