RFID Labels

RFID is a method of identifying unique items using radio waves. Typically, a reader communicates with a microchip embedded in a label which holds digital information. How Does RFID Work? Think of RFID as a system of several key components. These components are: a microchip with an antenna, a label that "carries" the microchip and a reader with an antenna that receives the microchip's signal. The reader sends out electromagnetic waves. The microchip's antenna is tuned to receive these waves. The chip then modulates the waves that the antenna sends back to the reader and the reader converts the new waves into digital data.
