RFID system consists of a tag, which is made up of a microchip whit an antenna, and an interrogator or reader with an antenna.
The reader sends out electromagnetic waves. The tag antenna is tuned to receive these waves .
A passive RFID tag draws power from field created by the reader and uses it to power the microchip's circuits.
The chip then modulates the waves that the tag sends back to readerand the reader converts the new waves into digital data.
